Member Function Documentation

assign()

void OutputFUResource::assign ( const int  cycle, MoveNode &  node  )

overridevirtual

There is actually nothing assigned here, only test that the OutputPSocket of given FU can be assigned.

Parameters

cycle	Cycle to assign
node	MoveNode assigned

Reimplemented from FUResource.
