Class TheOriginalJDTScannerClass

java.lang.Object

org.aspectj.org.eclipse.jdt.internal.compiler.parser.TheOriginalJDTScannerClass

All Implemented Interfaces:

TerminalTokens

Direct Known Subclasses:

Scanner

public class TheOriginalJDTScannerClass
extends java.lang.Object
implements TerminalTokens

IMPORTANT NOTE: Internal Scanner implementation. It is mirrored in org.aspectj.org.eclipse.jdt.core.compiler public package where it is API. The mirror implementation is using the backward compatible ITerminalSymbols constant definitions (stable with 2.0), whereas the internal implementation uses TerminalTokens which constant values reflect the latest parser generation state.
