gnu.text.SourceMessages

All Implemented Interfaces:

SourceLocator, SourceLocator, Locator

public class SourceMessages
extends SourceLocator.Simple

A collection of (zero or more) SourceErrors. Has a "current line number" which clients can use as the default line number, or clients can explicitly provide a line number. Does not handle localization of messages. Similar functionality as JAVA6's javax.tools.DiagnosticCollector.
