Class NPLDeclarations

java.lang.Object

com.nt.udc.ndk.node.NPLDeclarations

All Implemented Interfaces:

ConfigIfc

public final class NPLDeclarations
extends java.lang.Object
implements ConfigIfc

The main purpose of this class is to provide a clean interface to declarations in an NPL file. The user of this class must provide an NPLProgram object, and then will be able to query the NPLProgram object through the ConfigIfc interface. The query should be constructed according to the "block", "sub-block", and "setting" desired. Consider the following 2 examples. Given a ConfigIfc object "cfgifc", and a NPL declaration as follows, Config { ConfigSetting1 "true"; ConfigSetting2 "false"; } Expose for SomeAttrIDList { in.1; in.2; } then a query for the value of "ConfigSetting1" looks like this, Config.ConfigSetting1 which would return a value of: "true" from the following Java method call: String value = cfgifc.getItem("Config.ConfigSetting1"); and a query for the "SomeAttrIDList" declarations looks like this, Expose.SomeAttrIDList which would return a value of: "1,2" from the following Java method call: String value = cfgifc.getItem("Expose.SomeAttrIDList");
