  +--chartworks.es.plugin.nds.ParamInfoFactory

public class ParamInfoFactory

extends java.lang.Object

This Factory knows how to create a suitable ParamInfo instance according the the information passed in. All knowledge of which ParamInfo instance should be used should be contained in this factory. Two methods work in tandem: createParamInfo() creates a ParamInfo to represent a CDL paramenter, based on the param data passed in. createCDLParamWriter() creates the appropriate CDLParamWriter for a given ParamInfo instance. In this way the caller doesn't have to know details about the CDL parameters, nor how to write the CDL. The caller obtains a ParamInfo and later gets a CDLParamWriter that will output suitable CDL for the given ParamInfo and the data.
