Description

Internal class that stores values for cPar objects.

cPar delegates almost all methods to cParImpl. Delegation is used to conserve memory by using shared storage for module parameters that have the same values.

cParImpl is an abstract base class, which supports several data types via subclasses: cIntParImpl, cDoubleParImpl, cBoolParImpl, cStringParImpl, cObjectParImpl, cXMLParImpl.

Note: if the parameter is marked as non-volatile (isVolatile()==false), one should not set an expression as value. This is not enforced by cParImpl though.

Implemented in cStringParImpl, cObjectParImpl, cBoolParImpl, cDoubleParImpl, cIntParImpl, and cXMLParImpl.

◆ boolValue()

virtual bool boolValue ( cComponent * context ) const

pure virtual

Returns value as a boolean. The cParImpl type must be BOOL.

Implemented in cStringParImpl, cObjectParImpl, cBoolParImpl, cDoubleParImpl, cIntParImpl, and cXMLParImpl.

◆ intValue()

virtual intval_t intValue ( cComponent * context ) const

pure virtual

Returns value as an integer. The cParImpl type must be INT. Note: Implicit conversion from DOUBLE is intentionally missing.

◆ doubleValue()

virtual double doubleValue ( cComponent * context ) const

pure virtual

Returns value as a double. The cParImpl type must be DOUBLE. Note: Implicit conversion from INT is intentionally missing.

Implemented in cStringParImpl, cObjectParImpl, cBoolParImpl, cDoubleParImpl, cIntParImpl, and cXMLParImpl.

◆ stringValue()

virtual const char* stringValue ( cComponent * context ) const

pure virtual

Returns value as const char *. The cParImpl type must be STRING. This method may only be invoked when the parameter's value is a string constant and not the result of expression evaluation, otherwise an error is thrown. This practically means this method cannot be used on parameters declared as "volatile string" in NED; they can only be accessed using stdstringValue().

Implemented in cStringParImpl, cObjectParImpl, cBoolParImpl, cDoubleParImpl, cIntParImpl, and cXMLParImpl.

◆ stdstringValue()

virtual std::string stdstringValue ( cComponent * context ) const

pure virtual

◆ objectValue()

virtual cObject* objectValue ( cComponent * context ) const

pure virtual

Returns value as pointer to a cObject. The cParImpl type must be OBJECT.

Implemented in cStringParImpl, cObjectParImpl, cBoolParImpl, cDoubleParImpl, cIntParImpl, and cXMLParImpl.

◆ xmlValue()

virtual cXMLElement* xmlValue ( cComponent * context ) const

pure virtual

Returns value as pointer to cXMLElement. The cParImpl type must be XML.

Implemented in cStringParImpl, cObjectParImpl, cBoolParImpl, cDoubleParImpl, cIntParImpl, and cXMLParImpl.

◆ getExpression()

virtual cExpression* getExpression ( ) const

pure virtual

Returns pointer to the expression stored by the object, or nullptr.

Implemented in cStringParImpl, cObjectParImpl, cBoolParImpl, cDoubleParImpl, cIntParImpl, and cXMLParImpl.

◆ convertToConst()

virtual void convertToConst ( cComponent * context )

pure virtual

If the parameter contains an expression, this method replaces the stored expression with its evaluation. It preserves the stored file/line info, which may or may not be what is intended.

Implemented in cStringParImpl, cObjectParImpl, cBoolParImpl, cDoubleParImpl, cIntParImpl, and cXMLParImpl.

◆ parse()

virtual void parse	(	const char *	text,
		FileLine	loc
	)

pure virtual

Convert the value from string, and store the result. If the text cannot be parsed, an exception is thrown, which can be caught as std::runtime_error& if necessary.

Implemented in cStringParImpl, cObjectParImpl, cBoolParImpl, cDoubleParImpl, cIntParImpl, and cXMLParImpl.

◆ createWithType()

static cParImpl* createWithType ( Type type )

static

Factory method: creates a parameter object representing the given type.

◆ compare()

virtual int compare ( const cParImpl * other ) const

virtual

Compares two cParImpls, including name, type, flags, stored value or expression. Makes it possible to use cParImpl as a key in std::map or std::set.

Reimplemented in cStringParImpl, cObjectParImpl, cBoolParImpl, cDoubleParImpl, cIntParImpl, and cXMLParImpl.

◆ forEachChild() [1/2]

virtual void forEachChild	(	cVisitor *	v,
		cComponent *	context
	)

inlinevirtual

Needed for cPar's forEachChild().

Reimplemented in cObjectParImpl, and cXMLParImpl.

◆ getTotalParImplObjectCount()

static long getTotalParImplObjectCount ( )

inlinestatic

Returns the total number of objects created since the start of the program (or since the last reset). The counter is incremented by cOwnedObject constructor. Counter is signed to make it easier to detect if it overflows during very long simulation runs. May be useful for profiling or debugging memory leaks.

◆ getLiveParImplObjectCount()

static long getLiveParImplObjectCount ( )

inlinestatic

Returns the number of objects that currently exist in the program. The counter is incremented by cOwnedObject constructor and decremented by the destructor. May be useful for profiling or debugging memory leaks.

◆ resetParImplObjectCounters()

static void resetParImplObjectCounters ( )

inlinestatic

Reset counters used by getTotalObjectCount() and getLiveObjectCount(). (Note that getLiveObjectCount() may go negative after a reset call.)

◆ forEachChild() [2/2]

virtual void forEachChild

Enables traversing the object tree, performing some operation on each object. The operation is encapsulated in the particular subclass of cVisitor.

This method should be redefined in every subclass to call v->visit(obj) for every obj object contained.
