eu.bandm.tscore.base.Translet.Parser<String>

eu.bandm.tscore.base.Translet._REGEX

Enclosing class:

Translet

public static class Translet._REGEX
extends Translet.Parser<String>

Parser for text input following a regular expression. The Java Pattern mechanism is used directly, ie. Matcher.lookingAt(), see there for greedyness, etc. The result is the String consumed.

Field Summary

Fields

Modifier and Type	Field and Description
protected Format	name The pretty-print name of this parser.
protected Pattern	pattern The Java regex pattern compiled from the source text.
protected String	source The source text, standing for a Java regex pattern.

Constructor Summary

Constructors

Constructor and Description
_REGEX(String s) Only constructor with a string used directly as a Java RegEx pattern.

Method Summary

Modifier and Type	Method and Description
boolean	isTerminal() Whether the parser does directly consume character data.
Format	name(boolean full, Map<Translet.Recursive,String> names) Returns a user-readable text representation.
protected Set<Translet.State<String>>	parseOneState(Translet.State<?> st, 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.

_REGEX

public _REGEX(String s)

Only constructor with a string used directly as a Java RegEx pattern.

Method Detail

isTerminal

public boolean isTerminal()

Description copied from class: Translet.Parser

Whether the parser does directly consume character data. (is true for Translet._CONST, Translet._CAT and Translet._REGEX).

Overrides:

isTerminal in class Translet.Parser<String>

Returns:

false

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<String>

parseOneState

protected Set<Translet.State<String>> parseOneState(Translet.State<?> st,
                                                    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<String>

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<String>

Parameters:

full - whether storage constructs do appear in the rendering.

names - a map for managing the renderings of recursive calls
