Detailed Description

Contains class declarations for DtObjectIdInputPort, DtObjectIdOutputPort, and DtObjectIdPortData.

Instances of DtObjectIdOutputPort are input ports through which data consumers can receive DtEntityIdentifier data.

Constructor & Destructor Documentation

Member Function Documentation

virtual bool DtObjectIdInputPort::acceptType ( const DtString &  type ) const

virtual

Accepts DtObjectIdPortDataType.

Implements DtInputPort.

virtual void DtObjectIdInputPort::receiveData ( DtPortData *  data )

virtual

Overridden for optimization.

Instead of cloning the port data, it copies the int value to a local port data instance.

virtual const DtEntityIdentifier DtObjectIdInputPort::value ( ) const

virtual

Return the current value.
