de.unihalle.informatik.Alida.operator.ALDOpNodePort
public abstract class ALDOpNodePort
Abstract class for ports residing within opNodes. Derived sub classes are input and output ports. Each port knows the opNode it resides in and its index in the corresponding array of input or output ports in the opNode. The typeName is used only for printing purposes.
Furthermore a ALDOpNodePort may record properties of the ALDData as it is passed into or out of the operator. Specifically, the properties of the data are retrieved an recorded for input data just before the operate method is invoced, and for output data when the operate method returns. Also the explanation from the operator is copied as we may not keep a reference to it to allow garbage collection. Last the canaonical class name of the ALDData bound to the port is recorded, again for input data just before the operate method is invoced, and for output data when the operate method returns.
