Barbarian flight requires foot-hold? Your note totally solved my problem =) I was using two different runtimes, but when I removed the first one (leaving only the v4) it worked :D –Khaled Hassan Feb 28
Use only the v4 runtime (remove import org.antlr.runtime.ANTLRInputStream;) and see what happens. TokenSource A source of tokens must provide a sequence of tokens via TokenSource.nextToken() and also must reveal it's source of characters; CommonToken's text is computed from a CharStream; it only store All rights reserved.

The negative order integer challenge, but it's Prime Time! http://www.antlr.org/api/Java/org/antlr/v4/runtime/ANTLRInputStream.html If such a name is not known, this method returns IntStream.UNKNOWN_SOURCE_NAME. Token A token has properties: text, type, line, character position in the line (so we can ignore tabs), token channel, index, and source from which we obtained this token. LexerInterpreter ListTokenSource Provides an implementation of TokenSource as a wrapper around a list of Token objects.

RuntimeMetaData This class provides access to the current version of the ANTLR 4 runtime library as compile-time and runtime constants, along with methods for checking for matching version numbers and notifying TokenStreamRewriter Useful for rewriting out a buffered input token stream after doing some augmentation or other manipulations on it. This method is guaranteed to succeed if any of the following are true: i>0 i==-1 and index() returns a value greater than the value of index() after the stream was constructed I'm in the process of releasing ANTLRWorks 2.1 which will correct this mismatch." - 280Z28 Answer is Here share|improve this answer answered Oct 23 '13 at 2:07 Another Compiler Error 208214
Parser This is all the parsing support code essentially; most of it is error recovery stuff. int index() Return the current input symbol index 0..n where n indicates the last symbol has been read. Parameters: interval - an interval within the stream Returns: the text of the specified interval Throws: NullPointerException - if interval is null consume(CharStreaminput) protected boolean LexerATNSimulator.evaluatePredicate(CharStreaminput, intruleIndex, intpredIndex, booleanspeculative) Evaluate a predicate specified in the lexer.
LexerNoViableAltException NoViableAltException Indicates that the parser could not decide which of two or more paths to take based upon the remaining input. If a mark is released twice, or if marks are not released in reverse order of the corresponding calls to mark(), the behavior is unspecified.
