Package org.petitparser.tools

Class CompositeParser

java.lang.Object

org.petitparser.parser.Parser

org.petitparser.parser.combinators.DelegateParser

org.petitparser.tools.CompositeParser

@Deprecated
public abstract class CompositeParser
extends DelegateParser

Deprecated.

Helper to compose complex grammars from various primitive parsers.

Note, this class is deprecated in favor of GrammarDefinition that provides a more flexible way to define composite parsers.

To create a new composite grammar subclass CompositeParser. Override the method initialize() and for every production call def(String, org.petitparser.parser.Parser) giving the parsers a name. The start production must be named 'start'.

To refer to other productions use ref(String). To redefine or attach actions to productions use redef(String, Function), redef(String, org.petitparser.parser.Parser) and action(String, Function).

Method Detail

initialize

protected abstract void initialize()

Deprecated.

Automatically called by the framework to initialize the grammar.

ref

public final Parser ref(String name)

Deprecated.

Returns a reference to the production with the given name.

This method works during initialization and after completion of the initialization. During the initialization it returns delegate parsers that are eventually replaced by the real parsers. Afterwards it returns the defined parser (mostly useful for testing).

def

protected final void def(String name,
                         Parser parser)

Deprecated.

Defines a production with a name and a parser. Only call this method during initialization.

redef

protected final void redef(String name,
                           Parser parser)

Deprecated.

Redefines an existing production with a name and a new parser. Only call this method during initialization.

redef

protected final void redef(String name,
                           Function<Parser,Parser> function)

Deprecated.

Redefines an existing production with a name and a function producing a new parser. Only call this method during initialization.

action

protected final <S,T> void action(String name,
                                  Function<S,T> function)

Deprecated.

Attaches an action function to an existing production name. Only call this method during initialization.
