Detailed Description

The interface IZUnknown is used as the basic interface of the framework. It defines methods for memory management in C++. The concept is based on reference counters. Each call of addRef will increase the counter, each call of release() will decrease the counter. If the counter reaches zero, the object will be deleted automatically. When creating an new object, the reference counter is initalized with one and no addRef() must be called.

Member Function Documentation

addRef()

virtual void MQUALIFIER zeus::IZUnknown::addRef ( ) const

pure virtual

This method increases the reference counter of this object. The call is const because it will not change the content of the object, since the reference counter is not an object data. This allows to handle const reference using addRef() and release().

askForInterface()

virtual Retval MQUALIFIER zeus::IZUnknown::askForInterface ( const InterfaceID &  rInterfaceID, IZUnknown *&  rpIface  )

pure virtual

This method is used to cast to different interface types. This is a secure way asking for other implemented interfaces, since C++ does not reject invalid casts.

Parameters

rInterfaceID	: ID of the requested interface
rpIface	: return value of the interface. The pointer contains the address of the requested interface

Return values

RET_NOERROR	: Interface returned
RET_UNKNOWN_INTERFACE	: Interface is not valid or not implemented

release()

virtual void MQUALIFIER zeus::IZUnknown::release ( ) const

pure virtual

This method decreases the reference counter of this object. This call is const as well (like addRef()). The killing of an object is allowed by const method, because the content is not used any more.
