Get the name of this parser.

getName in interface Parser

tryThisOne

public boolean tryThisOne()

Description copied from interface: Parser

Whether this parser should be used when trying to parse a string with different parsers. This can be used to exclude special parsers from such attempts.

Specified by:

tryThisOne in interface Parser

parseWithAll

public static java.util.Collection<Pair<java.lang.String,Tree>> parseWithAll(Parsers parsers,
                                                                             java.lang.String str)

Try parsing the input with all the available parsers.

Returns:

A list of pairs (language, parse tree)
