public interface Parser

The interface for parser objects. The only responsibility of a parser is to return the parsability of input sentences. That is, parsers need only actually be recognizers/acceptors.

Specification of the grammar or model parameters is meant to be done by implementing classes' constructors. If there is no specification of a goal, then this will also be determined by the grammar or implementing class.

Method Detail

parse

boolean parse(List<? extends HasWord> sentence)

Parses the given sentence. For any words in the sentence which implement HasTag, the tag will be believed. The return value will be false if the sentence is not parseable. Acceptance is with respect to some goal category, which may be specified by the grammar, or may be a parser default (for instance, S).

Parameters:

sentence - A List<HasWord> to be parsed

Returns:

true iff the sentence is recognized

Throws:

UnsupportedOperationException - This will be thrown if for any reason the parser can't complete parsing this sentence, for example if the sentence is too long
