Member Function Documentation

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

virtual

Accepts DtEntityListPortDataType.

Implements DtInputPort.

virtual const DtEntityTargetList* DtEntityListMultiInputPort::firstValue ( )

virtual

Sets the interal iterator to the first set of data on the input port, and returns the value.

Retuns NULL if no more data.

virtual

Return the value at the current set of data on the port.

virtual const DtEntityTargetList* DtEntityListMultiInputPort::nextValue ( )

virtual

Advances the iterator to the next set of data on the port.

Retuns NULL if no more data.
