public class Sequence

extends CollectionParser

A Sequence object is a collection of parsers, all of which must in turn match against an assembly for this parser to successfully match.

Constructor Summary

Sequence()
Constructs a nameless sequence.

Sequence(java.lang.String name)
Constructs a sequence with the given name.

Method Summary

void	accept(ParserVisitor pv, java.util.Vector visited) Accept a "visitor" and a collection of previously visited parsers.
java.util.Vector	match(java.util.Vector in) Given a set of assemblies, this method matches this sequence against all of them, and returns a new set of the assemblies that result from the matches.
protected java.util.Vector	randomExpansion(int maxDepth, int depth)
protected java.lang.String	toStringSeparator() Helps to textually describe this CollectionParser.

Method Detail

accept

public void accept(ParserVisitor pv,
                   java.util.Vector visited)

Accept a "visitor" and a collection of previously visited parsers.

Overrides:

accept in class Parser

Parameters:

ParserVisitor - the visitor to accept

Vector - a collection of previously visited parsers

match

Overrides:

match in class Parser

Parameters:

Vector - a vector of assemblies to match against

Returns:

a Vector of assemblies that result from matching against a beginning set of assemblies

randomExpansion

                                           int depth)

Overrides:

randomExpansion in class Parser

toStringSeparator

protected java.lang.String toStringSeparator()

Description copied from class: CollectionParser

Helps to textually describe this CollectionParser.

Overrides:

toStringSeparator in class CollectionParser
