polyglot.frontend
Class ParserlessJLExtensionInfo

java.lang.Object
  polyglot.frontend.AbstractExtensionInfo
      polyglot.frontend.ParserlessJLExtensionInfo

All Implemented Interfaces:

ExtensionInfo

Direct Known Subclasses:

JLExtensionInfo

public abstract class ParserlessJLExtensionInfo
extends AbstractExtensionInfo

This class implements most of the ExtensionInfo for the Java language. It does not include a parser, however. EPL-licensed extensions should extend this class rather than JLExtensionInfo since they should not use the CUP-based grammar.
