Terence Parr 5c69d31e88 CommonTokenFactory now knows how to copy the text out of the character stream buffer before they disappear in unbuffered character strengths; added ctor. 
Lexer now guarantees that the text of the current token is always available to the emit() method even if the character stream is unbuffered.

Added some hooks to see some of the internal data in the unbuffered character stream so that I can test it better.

Updated LexerInterpreter so that it uses the token factory.

Improved/added unit tests for the unbuffered character string.

Updated various comments

Terence Parr abc0e2ef87 add getSpeculativeText(); text matched so far in a lexer rule. Use this in predicates not actions. add unit tests. 2012-06-07 18:31:36 -07:00
Terence Parr b255509e96 fix a bug related to semantic predicates in the lexer and generally cleaned up variable and method names in the simulator. I moved all of the predicates to the right side of lexer rules in the unit tests. Later, we should ensure that predicates only occur on the right edge of lexer rules. We should state that the rule is not been accepted so we can't test things like getText(), we have to use more raw indexes into the character stream. In the lexer simulator, the addDFAState() method now does not try to compute whether there is a predicate in the configurations. That information has already been set into the ATNConfigSet by the getEpsilonTarget() method. [I should also point out that I have not tested the Java parsing in a while and now it hits a landmine on a number of common Java files in jdk :(. I'm not sure where that crept in] 2012-06-07 17:31:18 -07:00
