Constructor/Destructor Detail

CValue

CValue();

Constructs the value.

The value is assigned type typeVoid .

~CValue

~CValue();

Destroys the value.

If this value is of type typeString or typeWstring , the memory allocated to hold string data is freed; if this value is of type typeInterace , the SOM object associated with this value is released (applying Core::CInterface::Release to that object).

Function Detail

CreateAny

void CreateAny(const CValue &value);

Reinitializes this value, making a copy of another (source) value.

If the source value is of type typeString or typeWstring , the separate block of memory is allocated to hold a copy of string data for this value. If the source value is of type typeInterface , the proper reference counting is performed for the corresponding SOM object. The previous content of this value is destroyed.

Parameters:: value - the source value
