Method Detail

continueRecoverOnError

public ProcessReturn continueRecoverOnError(Lexer<B> lexer,
                                            ActionProcessor<R> processor)

Description copied from interface: LexerErrorRecoveryPolicy

Called when error recovery was initiated by recover on error, and method LexerErrorRecoveryPolicy.errorRecoveryNeedsContinuation() returns true

Specified by:

continueRecoverOnError in interface LexerErrorRecoveryPolicy<R,B extends LexerBuffer>

Parameters:

lexer - the lexer

processor - the action processor

Returns:

MORE if more characters are needed, ERROR, if error recovery fails and TOKEN if a new token is spawned.

continueRecoverOnUnexpectedEndOfFile

public ProcessReturn continueRecoverOnUnexpectedEndOfFile(Lexer<B> lexer,
                                                          ActionProcessor<R> processor)

Description copied from interface: LexerErrorRecoveryPolicy

Called when error recovery was initiated by recover on error, and method LexerErrorRecoveryPolicy.unexpectedEndOfFileRecoveryNeedsContinuation() returns true

Specified by:

continueRecoverOnUnexpectedEndOfFile in interface LexerErrorRecoveryPolicy<R,B extends LexerBuffer>

processor - the action processor

Returns:

MORE if more characters are needed, ERROR, if error recovery fails and TOKEN if a new token is spawned.

errorRecoveryNeedsContinuation

public boolean errorRecoveryNeedsContinuation()

Description copied from interface: LexerErrorRecoveryPolicy

Indicate if LexerErrorRecoveryPolicy.continueRecoverOnError(fr.umlv.tatoo.runtime.lexer.Lexer, fr.umlv.tatoo.runtime.lexer.rules.ActionProcessor) needs to be called by processor

Specified by:

errorRecoveryNeedsContinuation in interface LexerErrorRecoveryPolicy<R,B extends LexerBuffer>

Returns:

true if LexerErrorRecoveryPolicy.continueRecoverOnError(fr.umlv.tatoo.runtime.lexer.Lexer, fr.umlv.tatoo.runtime.lexer.rules.ActionProcessor) needs to be called by processor

recoverOnError

public void recoverOnError(Lexer<B> lexer,
                           ActionProcessor<R> processor)

Description copied from interface: LexerErrorRecoveryPolicy

Called when the impossible match first occurs. If necessary, LexerErrorRecoveryPolicy.errorRecoveryNeedsContinuation() returns true and LexerErrorRecoveryPolicy.continueRecoverOnError(fr.umlv.tatoo.runtime.lexer.Lexer, fr.umlv.tatoo.runtime.lexer.rules.ActionProcessor) is called
