eu.bandm.tscore.base.Translet.HeadParser<A>

Enclosing class:

Translet

public static class Translet.HeadParser<A>
extends Translet.Parser<A>

Accepts a sequence "A,B,..", where only the very first parsing/processing result is stored as result in the Translet.State object, discarding all the tail.

Field Summary

Fields

Modifier and Type	Field and Description
protected Translet.Parser<A>	p1 The hear parser, result of which will become the result of this.
protected List<Translet.Parser<?>>	seps List of following parsers, not contributing to result.

Constructor Summary

Constructors

Constructor and Description
HeadParser(Translet.Parser<A> p1, List<Translet.Parser<?>> seps) Only constructor, setting the first and the following parsers.
HeadParser(Translet.Parser<A> p1, Translet.Parser<?>[] seps) Only constructor, setting the first and the trailing parsers.

Method Summary

Modifier and Type	Method and Description
Format	name(boolean full, Map<Translet.Recursive,String> names) Returns a user-readable text representation.
Set<Translet.State<A>>	parseOneState(Translet.State<?> inState, Set<Translet.Alternative> alternatives) Calculate a set of possible successor states by applying this parser to the incoming state and append all altenatives found underways to the parameter "alternatives".
String	unparse(Object key) Reverse the parsing process (as far as possible) and deliver a string representation which when parsed delivered the parse result.

Method Detail

unparse

public String unparse(Object key)

Description copied from class: Translet.Parser

Reverse the parsing process (as far as possible) and deliver a string representation which when parsed delivered the parse result.

Specified by:

unparse in class Translet.Parser<A>

parseOneState

public Set<Translet.State<A>> parseOneState(Translet.State<?> inState,
                                            Set<Translet.Alternative> alternatives)

Description copied from class: Translet.Parser

Calculate a set of possible successor states by applying this parser to the incoming state and append all altenatives found underways to the parameter "alternatives". This method is specific to and overridden by the subclasses of Parser.

Specified by:

parseOneState in class Translet.Parser<A>

name

public Format name(boolean full,
                   Map<Translet.Recursive,String> names)

Description copied from class: Translet.Parser

Returns a user-readable text representation. This is in most cases, but not always, source text to construct the parser.

Specified by:

name in class Translet.Parser<A>

Parameters:

full - whether storage constructs do appear in the rendering.

names - a map for managing the renderings of recursive calls
