Package com.ibm.di.server

Class FunctionComponent

java.lang.Object

com.ibm.di.server.AssemblyLineComponent

com.ibm.di.server.FunctionComponent

All Implemented Interfaces:

java.util.Map

public class FunctionComponent
extends AssemblyLineComponent

This is a wrapper class for IBM Tivoli Directory Integrator Function Components. Objects of this class are instantiated by the AssemblyLine, as the AssemblyLine only works with AssemblyLineComponent objects, not Connectors, Functions Components, etc.
