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

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 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.
