Class DeclNPLFieldProcessor

java.lang.Object

com.nt.udc.ndk.node.DCFieldProcessor

com.nt.udc.ndk.node.DeclNPLFieldProcessor

All Implemented Interfaces:

DataProviderIfc, DataReceiverIfc, FileDataProviderIfc, FileDataReceiverIfc, java.lang.Runnable

Direct Known Subclasses:

AggregatorFieldProcessor, DiscProcFieldProcessor, DupRemoverFieldProcessor, SeqProcFieldProcessor

public abstract class DeclNPLFieldProcessor
extends DCFieldProcessor

This field processor is intended for those nodes that can not use procedural NPL, but still required the declarative configuration elements of NPL. A derived field processor will have access to those configuration elements through the "getNPLConfig()" method. Please refer to the Java documentation for the class "NPLDeclarations" for more information on how to obtain the desired configuration element from the NPL file.
