Parse4j can parse using ambiguous
grammar and output alternative for ambiguities.
In some case, generally bugged grammar, the number of alternative
is so huge that an "out of memory java heap space" occurs while
parsing. This occurs after à long execution time. To avoid this the
number of alternative is limited. The maximum number of alternative for
ambiguity is fixed to 10 by default, it can be set to other value using
Accepting ambiguity or not can be set when call parser.
If ambiguity is not accepted and ambiguity is found then exception is throw and ambiguous parse nodes are logged.
Avoid ambiguity can be done in two
