cValueMap Class Reference

Description

Key-value container class based on std::map<std::string,cValue>.

The added value is ownership handling of object values (cObject* pointers) contained in cValue objects. Guidelines: owned objects are those that subclass from cOwnedObject and getOwner() returns this object, and all cObjects that are non-cOwnedObject.

Constructor & Destructor Documentation

cValueMap() [1/2]

cValueMap ( const cValueMap &  other )

inline

Copy constructor. Contained objects will be duplicated so that the new cValueArray will have its own copy of them.

Note that this behavior is different from most other container classes in the simulation library like cQueue, which only duplicate the objects they own, and leave externally owned objects alone.

cValueMap() [2/2]

cValueMap ( const char *  name = nullptr )

inlineexplicit

Constructor.

~cValueMap()

virtual ~cValueMap ( )

virtual

Destructor. The contained objects that were owned by the container will be deleted.

Member Function Documentation

operator=()

cValueMap& operator=

(

const cValueMap &

other

)

Assignment operator. The name member is not copied; see cNamedObject::operator=() for details. Contained objects that are owned by cValueMap will be duplicated so that the new cValueMap will have its own copy of them.

dup()

virtual cValueMap* dup ( ) const

inlineoverridevirtual

Creates and returns an exact copy of this object. Contained objects will be duplicated so that the new cValueMap will have its own copy of them.

Note that this behavior is different from most other container classes in the simulation library like cQueue, which only duplicate the objects they own, and leave externally owned objects alone.

Reimplemented from cObject.

str()

virtual std::string str ( ) const

overridevirtual

Produces a one-line description of the object's contents. See cObject for more details.

Reimplemented from cObject.

forEachChild()

virtual void forEachChild ( cVisitor *  v )

overridevirtual

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

Reimplemented from cObject.

size()

virtual int size ( ) const

inlinevirtual

Returns the number of entries in the map.

clear()

virtual void clear ( )

virtual

Makes the container empty.

set()

virtual void set ( const char *  key, const cValue &  value  )

virtual

Adds or overwrites an entry in the map.

containsKey()

virtual bool containsKey ( const char *  key ) const

virtual

Returns true if the given key is present in the map.

get()

virtual const cValue& get ( const char *  key ) const

virtual

Returns the value with the given key.

operator[]()

const cValue& operator[] ( const char *  key ) const

inline

Equivalent to get(const char *) const.

erase()

virtual void erase ( const char *  key )

virtual

Erases the entry with the given key.

getFields()

const std::map<std::string,cValue>& getFields ( ) const

inline

Provides readonly access to the underlying std::map.
