Detailed Description

template<class INTERFACE>
class IlvCOMInterface< INTERFACE >

This class queries for a specific interface from an IUnknown* or from another IlvAbstractCOMInterface.

Library: ilvcom

Constructor & Destructor Documentation

template<class INTERFACE >
IlvCOMInterface< INTERFACE >::IlvCOMInterface ( )

Default constructor.

This constructor initializes the internal data members. It also initializes the COM library if required.

template<class INTERFACE >
IlvCOMInterface< INTERFACE >::IlvCOMInterface ( IlvCOMInterface< INTERFACE > const &  interf)

Copy constructor.

This constructor initializes the internal data members by copying the values of the object other.

template<class INTERFACE>
IlvCOMInterface< INTERFACE >::IlvCOMInterface ( INTERFACE *  interf)

Constructor used to encapsulate a pointer to an INTERFACE.

This lets this class to be used as a shared pointer.

Parameters
interfA pointer to an INTERFACE (type of the template) to be encapsulated into this class.

template<class INTERFACE>
IlvCOMInterface< INTERFACE >::IlvCOMInterface ( IUnknown *  iUnknown,
REFIID  rIID 
)

Constructor from an IUnknown*.

This constructor queries for an interface, described by the REFIID rIID from the IUnknown given as first parameter.

Parameters
iUnknownA pointer to an IUnknown.
rIIDA REFIID that describes the interface to query for.
