Interface Parser

All Known Implementing Classes:

ChartParser, ParseDecimal, ParseTree

public interface Parser

Interface for all parsers from text to abstract syntax.

Method Summary

java.lang.String	getName() Get the name of this parser.
java.util.Collection<Tree>	parse(java.lang.String str) Parse a string to zero or more abstract syntax trees the parsers default category.
java.util.Collection<Tree>	parse(java.lang.String str, java.lang.String cat) Parse a string to zero or more abstract syntax trees in the given category.
boolean	tryThisOne() Whether this parser should be used when trying to parse a string with different parsers.

Method Detail

parse

java.util.Collection<Tree> parse(java.lang.String str)

Parse a string to zero or more abstract syntax trees the parsers default category.

parse

java.util.Collection<Tree> parse(java.lang.String str,
                                 java.lang.String cat)

Parse a string to zero or more abstract syntax trees in the given category.

Parameters:

cat - The category to parse in. Note that the category name given here might not be identical to the one in the GF grammar, as the conversion to a context-free grammar can change the category name. Typically, for non-dependent categories, the GF source category "C" is translated to "C{}.s".

getName

java.lang.String getName()

Get the name of this parser.

tryThisOne

boolean tryThisOne()

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.
