All Implemented Interfaces:

Parameters

public class ParameterSet

extends java.lang.Object

implements Parameters

This class implements Parameters. It supports add and get methods for Param type objects. Once added, a Param object cannot be removed from this ParameterSet. Internally, a Vector stores all the Param and a Hashtable holds pointers to these Param objects for fast retrieval when specific get methods is used.
