#include <cmodule.h>

Description

This class represents modules in the simulation.

cModule can be used directly for compound modules. Simple module classes need to be subclassed from cSimpleModule, a class that adds more functionality to cModule.

For navigating the module tree, see: getParentModule(), getSubmodule(), cModule::SubmoduleIterator, cModule::getModuleByPath(), cSimulation::getModuleByPath().

Constructor & Destructor Documentation

◆ cModule()

cModule ( )

Constructor. Note that module objects should not be created directly, only via their cModuleType objects. cModuleType::create() will do all housekeeping tasks associated with module creation (assigning an ID to the module, inserting it into the global simulation object (see cSimulation), etc.).

◆ ~cModule()

virtual ~cModule ( )

virtual

Destructor. Note: it is not allowed delete modules directly, only via the deleteModule() method.

Member Function Documentation

◆ forEachChild()

virtual void forEachChild ( cVisitor * v )

overridevirtual

Calls v->visit(this) for each contained object. See cObject for more details.

Reimplemented from cComponent.

Reimplemented in cSimpleModule.

◆ setName()

virtual void setName ( const char * s )

overridevirtual

Sets module's name. If the module is part of a submodule vector, the name change implies relocating the module into another submodule vector (which must already exist, and the same index position in it must be available and empty).

See also: setIndex(), setNameAndIndex()

Reimplemented from cNamedObject.

◆ getFullName()

virtual const char* getFullName ( ) const

overridevirtual

Returns the full name of the module, which is getName() plus the index in square brackets (e.g. "module[4]"). Redefined to add the index.

Reimplemented from cObject.

◆ getFullPath()

virtual std::string getFullPath ( ) const

overridevirtual

Returns the full path name of the module. Example: "net.node[12].gen". The original getFullPath() was redefined in order to hide the global cSimulation instance from the path name.

Reimplemented from cObject.

◆ str()

virtual std::string str ( ) const

overridevirtual

Overridden to add the module ID.

Reimplemented from cSoftOwner.

Reimplemented in cSimpleModule.

◆ setIndex()

virtual void setIndex ( int index )

virtual

Sets the module's index. The module must be part of a submodule vector. The index change implies relocating the module into another slot in the same submodule vector; the destination index position must be available and empty.

◆ setNameAndIndex()

virtual void setNameAndIndex	(	const char *	name,
		int	index = `-1`
	)

virtual

Sets the module's name and index. If index is not -1, the change implies relocating the module into another submodule vector and index position. The destination submodule vector must already exist, and its indexth slot must be available and empty.

◆ addGate()

virtual cGate* addGate	(	const char *	gatename,
		cGate::Type	type
	)

virtual

Adds a scalar gate of the given type to the module. If type is INOUT, two gate objects will be created, "gatename$i" and "gatename$o" (the specified gatename must not contain a "$i" or "$o" suffix itself).

Returns a pointer to the new gate if type is INPUT or OUTPUT, and nullptr if type is INOUT.

◆ addGateVector()

virtual void addGateVector	(	const char *	gatename,
		cGate::Type	type,
		int	size
	)

virtual

Adds a gate vector of the given type and size to the module. If type is INOUT, two gate vectors will be created, "gatename$i[]" and "gatename$o[]" (the specified gatename must not contain a "$i" or "$o" suffix itself).

◆ setGateSize()

virtual void setGateSize	(	const char *	gatename,
		int	size
	)

virtual

Sets gate vector size. The specified gatename must not contain a "$i" or "$o" suffix: it is not possible to set different vector size for the "$i" or "$o" parts of an inout gate. Changing gate vector size is guaranteed NOT to change any gate IDs.

◆ getOrCreateFirstUnconnectedGate()

virtual cGate* getOrCreateFirstUnconnectedGate	(	const char *	gatename,
		char	suffix,
		bool	inside,
		bool	expand
	)

virtual

Helper function for implementing NED's "gate++" syntax. Returns the next unconnected gate from an input or output gate vector, or input/output half of an inout vector. When gatename names an inout gate vector, the suffix parameter should be set to 'i' or 'o' to select "gatename$i" or "gatename$o"; otherwise suffix should be zero. The inside parameter selects whether to use isConnectedInside() or isConnectedOutside() to test if the gate is connected. The expand parameter tells whether the gate vector should be expanded if all its gates are used up.

◆ getOrCreateFirstUnconnectedGatePair()

virtual void getOrCreateFirstUnconnectedGatePair	(	const char *	gatename,
		bool	inside,
		bool	expand,
		cGate *&	gatein,
		cGate *&	gateout
	)

virtual

Helper function to implement NED's "gate++" syntax. This variant accepts inout gates only, and the result is returned in the gatein and gateout parameters. The meaning of the inside and expand parameters is the same as with getOrCreateFirstUnconnectedGate().

◆ finalizeParameters()

virtual void finalizeParameters ( )

overridevirtual

Redefined from cComponent. This method must be called as part of the module creation process, after moduleType->create() and before mod->buildInside(). It finalizes parameter values (e.g. reads the missing ones from omnetpp.ini), and adds gates and gate vectors (whose size may depend on parameter values) to the module.

So the sequence of setting up a module is:

modType->create()
set parameter values
mod->finalizeParameters() – this creates gates too
connect gates (possibly adding new gates via gate++ operations)
mod->buildInside()

The above sequence also explains why finalizeParameters() cannot by merged into either create() or buildInside().

Reimplemented from cComponent.

◆ buildInside()

void buildInside ( )

In compound modules, this method should be called to create submodules and internal connections after module creation.

This method delegates to doBuildInside(), switching the context to this module for the duration of the call (see simulation.setContextModule()).

See also: doBuildInside()

◆ isSimple()

virtual bool isSimple ( ) const

virtual

Returns true if the C++ class of this module is a subclass of cSimpleModule, and false otherwise, i.e. it is equivalent to a dynamic_cast.

In contrast, to check whether this module is a NED compound or simple module (i.e. whether it was declared with the "module" or with the "simple" keyword in NED), use cModuleType::isSimple(): getModuleType()->isSimple().

Reimplemented in cSimpleModule.

◆ getComponentKind()

virtual ComponentKind getComponentKind ( ) const

inlineoverridevirtual

Redefined from cComponent to return KIND_MODULE.

Implements cComponent.

◆ isPlaceholder()

virtual bool isPlaceholder ( ) const

inlinevirtual

Returns true if this module is a placeholder module, i.e. represents a remote module in a parallel simulation run.

◆ getParentModule()

virtual cModule* getParentModule ( ) const

inlineoverridevirtual

Returns the module containing this module. For the system module, it returns nullptr.

Implements cComponent.

◆ getModuleType()

cModuleType* getModuleType ( ) const

inline

Convenience method: casts the return value of getComponentType() to cModuleType.

◆ getProperties()

virtual cProperties* getProperties ( ) const

overridevirtual

Return the properties for this module. Properties cannot be changed at runtime. Redefined from cComponent.

Implements cComponent.

◆ isVector()

bool isVector ( ) const

inline

Returns true if this module is in a module vector.

◆ getIndex()

int getIndex ( ) const

Returns the index of the module in a module vector. If the module is not member of a module vector, an exception is thrown.

◆ getVectorSize()

int getVectorSize ( ) const

Returns the size of the module vector the module is in. If the module is not member of a module vector, an exception is thrown.

◆ hasSubmodules()

virtual bool hasSubmodules ( ) const

virtual

Returns true if the module has submodules, and false otherwise. To enumerate the submodules use SubmoduleIterator.

◆ hasSubmoduleVector()

virtual bool hasSubmoduleVector ( const char * name ) const

virtual

Returns true if the module has a submodule vector (not necessarily of nonzero size) of the given name, and false otherwise.

◆ getSubmoduleVectorNames()

virtual std::vector<std::string> getSubmoduleVectorNames ( ) const

virtual

Returns the names of the module's submodule vectors, including zero-size submodule vectors.

◆ getSubmoduleVectorSize()

virtual int getSubmoduleVectorSize ( const char * name ) const

virtual

Returns the size of the submodule vector of the given name. Throws an error if there is no such submodule vector.

◆ addSubmoduleVector()

virtual void addSubmoduleVector	(	const char *	name,
		int	size
	)

virtual

Adds a blank submodule vector with the given name and size. Throws an error if a submodule vector with the given name already exists.

Important: This operation does NOT actually create any submodules. The slots in the vector will be nullptr, i.e. getSubmodule(name,index) returns nullptr for all indices.

Modules can be added one by one by using cModuleType::create(name, parentModule, index). Deleting a module (via cModule::deleteModule()) which is part of a submodule vector will also remove it from the submodule vector and set its slot to nullptr.

◆ deleteSubmoduleVector()

virtual void deleteSubmoduleVector ( const char * name )

virtual

Deletes the submodule vector with the given name. All submodules in the given vector will be deleted. Throws an error if a submodule vector with the given name does not exist.

◆ setSubmoduleVectorSize()

virtual void setSubmoduleVectorSize	(	const char *	name,
		int	size
	)

virtual

Resizes the given submodule vector, filling new elements with nullptr. A submodule vector can be extended any time; it can be shrunk only if it contains no submodules in the index range which is going to be removed. Throws an error if there is no such submodule vector, or the removed range contains submodules. Modules can be removed from the submodule vector by calling their deleteModule() method.

◆ addSubmodule()

virtual cModule* addSubmodule	(	cModuleType *	type,
		const char *	name,
		int	index = `-1`
	)

virtual

Creates and initializes a submodule. If index is present, then the submodule becomes an element in a submodule vector; the submodule vector of the given name must already exist, have a sufficient size (size>index), and the indexth position must be empty.

Note: This method just delegates to cModuleType::createScheduleInit(). If parameters need to be set or gates need to be connected before building the internal structure (in case type is a compound module) and initializing the module, use cModuleType::create() instead of this method.

See also: cModuleType::createScheduleInit(), cModuleType::create()

◆ hasSubmodule()

virtual bool hasSubmodule	(	const char *	name,
		int	index = `-1`
	)		const

virtual

Returns true if a submodule with the given name (and index) exists, and false otherwise. Index must be specified exactly if the module is member of a module vector.

◆ findSubmodule()

virtual int findSubmodule	(	const char *	name,
		int	index = `-1`
	)		const

virtual

Finds a direct submodule with the given name and index, and returns its module ID. If the submodule was not found, returns -1. Index must be specified exactly if the module is member of a module vector.

◆ getSubmodule()

virtual cModule* getSubmodule	(	const char *	name,
		int	index = `-1`
	)		const

virtual

Finds a direct submodule with the given name and index, and returns its pointer. If the submodule was not found, returns nullptr. Index must be specified exactly if the module is member of a module vector.

◆ getSubmoduleNames()

virtual std::vector<std::string> getSubmoduleNames ( ) const

virtual

Returns the names of the module's submodules and submodule vectors, including zero-size submodule vectors.

◆ containsModule()

virtual bool containsModule ( cModule * module ) const

virtual

Returns true of the given module has this module as an ancestor, and false otherwise.

◆ hasGates()

virtual bool hasGates ( ) const

virtual

Returns true if the module has any gates, and false otherwise. If it does, getGateNames() or GateIterator be used to enumerate them.

◆ gate() [1/4]

virtual cGate* gate	(	const char *	gatename,
		int	index = `-1`
	)

virtual

Looks up a gate by its name and index. Gate names with the "$i" or "$o" suffix are also accepted. Throws an error if the gate does not exist. The presence of the index parameter decides whether a vector or a scalar gate will be looked for.

◆ gate() [2/4]

const cGate* gate	(	const char *	gatename,
		int	index = `-1`
	)		const

inline

Looks up a gate by its name and index. Gate names with the "$i" or "$o" suffix are also accepted. Throws an error if the gate does not exist. The presence of the index parameter decides whether a vector or a scalar gate will be looked for.

◆ gateHalf() [1/2]

virtual cGate* gateHalf	(	const char *	gatename,
		cGate::Type	type,
		int	index = `-1`
	)

virtual

Returns the "$i" or "$o" part of an inout gate, depending on the type parameter. That is, gateHalf("port", cGate::OUTPUT, 3) would return gate "port$o[3]". Throws an error if the gate does not exist. The presence of the index parameter decides whether a vector or a scalar gate will be looked for.

◆ gateHalf() [2/2]

const cGate* gateHalf	(	const char *	gatename,
		cGate::Type	type,
		int	index = `-1`
	)		const

inline

Returns the "$i" or "$o" part of an inout gate, depending on the type parameter. That is, gateHalf("port", cGate::OUTPUT, 3) would return gate "port$o[3]". Throws an error if the gate does not exist. The presence of the index parameter decides whether a vector or a scalar gate will be looked for.

◆ hasGate()

virtual bool hasGate	(	const char *	gatename,
		int	index = `-1`
	)		const

virtual

Checks if a gate exists. When invoked without index, it returns whether gate "gatename" or "gatename[]" exists (no matter if the gate vector size is currently zero). When invoked with an index, it returns whether the concrete "gatename[index]" gate exists (gatename being a vector gate). Gate names with the "$i" or "$o" suffix are also accepted.

◆ findGate()

virtual int findGate	(	const char *	gatename,
		int	index = `-1`
	)		const

virtual

Returns the ID of the gate specified by name and index. Inout gates cannot be specified (since they are actually two gate objects, not one), only with a "$i" or "$o" suffix. Returns -1 if the gate does not exist. The presence of the index parameter decides whether a vector or a scalar gate will be looked for.

◆ gate() [3/4]

virtual cGate* gate ( int id )

virtual

Returns a gate by its ID. It throws an error for invalid (or stale) IDs.

Note: as of OMNeT++ 4.0, gate IDs are no longer small integers and are not suitable for enumerating all gates of a module. Use GateIterator for that purpose.

◆ gate() [4/4]

const cGate* gate ( int id ) const

inline

Returns a gate by its ID. It throws an error for invalid (or stale) IDs.

Note: as of OMNeT++ 4.0, gate IDs are no longer small integers and are not suitable for enumerating all gates of a module. Use GateIterator for that purpose.

References cModule::gate().

Referenced by cModule::gate().

◆ deleteGate()

virtual void deleteGate ( const char * gatename )

virtual

Deletes a gate, gate pair, or gate vector. Note: individual gates in a gate vector and one side of an inout gate (i.e. "foo$i") cannot be deleted. IDs of deleted gates will not be reused later.

◆ getGateNames()

virtual std::vector<std::string> getGateNames ( ) const

virtual

Returns the names of the module's gates. For gate vectors and inout gates, only the base name is returned (without gate index, "[]" or the "$i"/"$o" suffix). Zero-size gate vectors will also be included.

See also: gateType(), isGateVector(), gateSize()

◆ gateType()

virtual cGate::Type gateType ( const char * gatename ) const

virtual

Returns the type of the gate (or gate vector) with the given name. Gate names with the "$i" or "$o" suffix are also accepted. Throws an error if there is no such gate or gate vector.

◆ hasGateVector()

virtual bool hasGateVector ( const char * gatename ) const

virtual

Returns true if there is a gate vector with the given name, and false otherwise. Names with the "$i" and "$o" suffix are also accepted. Zero-size gate vectors will also be included.

◆ isGateVector()

virtual bool isGateVector ( const char * gatename ) const

virtual

Returns whether the given gate is a gate vector. Gate names with the "$i" or "$o" suffix are also accepted. Throws an error if there is no such gate or gate vector.

virtual int gateSize ( const char * gatename ) const

virtual

Returns the size of the gate vector with the given name. Gate names with the "$i" or "$o" suffix are also accepted. Throws an error if there is no such gate, or it is not a gate vector.

See also: cGate::getVectorSize()

◆ gateBaseId()

virtual int gateBaseId ( const char * gatename ) const

virtual

For vector gates, it returns the ID of gate 0 in the vector, even if the gate size is currently zero. All gates in the vector can be accessed by ID = gateBaseId + index. For scalar gates, it returns the ID of the gate. If there is no such gate or gate vector, an error gets thrown.

Note: Gate IDs are guaranteed to be stable, i.e. they do not change if the gate vector gets resized, or other gates get added/removed.

◆ checkInternalConnections()

virtual bool checkInternalConnections ( ) const

virtual

For compound modules, it checks if all gates are connected inside the module (it returns true if they are OK); for simple modules, it returns true. This function is called during network setup.

◆ arrived()

virtual void arrived	(	cMessage *	msg,
		cGate *	ongate,
		const SendOptions &	options,
		simtime_t	t
	)

virtual

This method is invoked as part of a send() call in another module. It is called when the message arrives at a gates in this module which is not further connected, that is, the gate's getNextGate() method returns nullptr. The default, cModule implementation reports an error ("message arrived at a compound module"), and the cSimpleModule implementation inserts the message into the FES after some processing.

Reimplemented in cSimpleModule.

◆ getAncestorPar()

virtual cPar& getAncestorPar ( const char * parname )

virtual

Searches for the parameter in the parent modules, up to the system module. If the parameter is not found, throws cRuntimeError.

◆ getCanvas()

virtual cCanvas* getCanvas ( ) const

virtual

Returns the default canvas for this module, creating it if it hasn't existed before.

◆ getOsgCanvas()

virtual cOsgCanvas* getOsgCanvas ( ) const

virtual

Returns the default 3D (OpenSceneGraph) canvas for this module, creating it if it hasn't existed before.

◆ setBuiltinAnimationsAllowed()

virtual void setBuiltinAnimationsAllowed ( bool enabled )

inlinevirtual

Sets whether built-in animations are requested on this module's graphical inspector.

◆ getBuiltinAnimationsAllowed()

virtual bool getBuiltinAnimationsAllowed ( ) const

inlinevirtual

Returns true if built-in animations are requested on this module's graphical inspector, and false otherwise.

◆ callInitialize() [1/2]

virtual void callInitialize ( )

overridevirtual

Interface for calling initialize() from outside.

Implements cComponent.

◆ callInitialize() [2/2]

virtual bool callInitialize ( int stage )

overridevirtual

Interface for calling initialize() from outside. It does a single stage of initialization, and returns true if more stages are required.

Implements cComponent.

◆ callFinish()

virtual void callFinish ( )

overridevirtual

Interface for calling finish() from outside.

Implements cComponent.

◆ scheduleStart()

virtual void scheduleStart ( simtime_t t )

virtual

Creates a starting message for modules that need it (and recursively for its submodules).

Reimplemented in cSimpleModule.

◆ deleteModule()

virtual void deleteModule ( )

virtual

Deletes the module and recursively all its submodules.

A running module can also delete itself. When an activity()-based simple module deletes itself from within its activity(), the deleteModule() call will not return (it throws an exception which gets caught by the simulation kernel, and the simulation kernel will delete the module).

When a handleMessage()-based module deletes itself, the deleteModule() returns normally – then, of course, the code should not try to access data members or functions of the deleted module, and should return as soon as possible.

It is not allowed to delete the system module. Also, a module cannot be deleted while its initialization is in progress.

◆ changeParentTo()

virtual void changeParentTo ( cModule * mod )

virtual

Moves the module under a new parent module. This functionality may be useful for some (rare) mobility scenarios.

NOTE: THIS METHOD CHANGES THE MODULE ID. To maintain a time-independent moduleId-to-fullPath mapping, this method will cause this module, and all modules under it in the module hierarchy, to be assigned a new ID. This usually causes no problem in the simulation's operation, but if your model stores module IDs somewhere, you'll need to invalidate or update them manually.

This function could bypass several rules which are enforced when you build the model using NED, so you must observe the following:

you cannot insert the module under one of its own submodules. This is checked by this function.
gates of the module cannot be connected when you move it. If you moved a module which is connected to its parent module or to other submodules, you'd create connections that do not obey the module hierarchy, and this is not permitted. This rule is also enforced by the implementation of this function.
it is recommended that the module name be made unique among the submodules of its new parent.
if the module is part of a module vector, the new parent must already have a submodule vector of the same name, with size>index, and the corresponding (indexth) array element being vacant (nullptr).
