Action

Class Overview

Actions are fired when their subject parser matches. The Callback class is passed the matching portion of the parse text. Note that the Action parser wraps around its subject. It will parse exactly the same text that its subject parser parses. Parser p = Chset.ALPHA.plus().action(new Callback() { public void handle(char[] buf, int start, int end, Object data) { StringBuffer str = (StringBuffer) data; str.delete(0, str.length()); str.append(buf, start, end - start); } }); StringBuffer buf = new StringBuffer(); p.parse("a") -> matches "a", buf == "a" p.parse("abcde") -> matches "abcde", buf == "abcde" p.parse("a0") -> matches "a", buf == "a" p.parse("0") -> no match, buf unchanged

From class com.google.gdata.util.parser.Parser final <U extends T> Parser<U> action(Callback<U> callback) Creates a Action that will fire and call Callback.handle whenever this matches. static <T> Parser<T> alternative(Parser<? super T> left, Parser<? super T> right) Creates an Alternative parser from the left and right sub-parsers. static <T> Parser<T> difference(Parser<? super T> left, Parser<? super T> right) Creates a Difference parser from the left and right sub-parsers. static <T> Parser<T> intersection(Parser<? super T> left, Parser<? super T> right) Creates an Intersection parser from the left and right sub-parsers. final Parser<T> list(Parser<? super T> sep) Creates a Parser that matches a sequence of this parsers separated by sep parsers. final Parser<T> optional() Creates a Repeat parser that matches this either 0 or 1 times. final int parse(String str, T udata) Convenience routine to parse a string. abstract int parse(char[] buf, int start, int end, T udata) The parse interface that subclasses must implement. final int parse(Reader reader, T udata) Convenience routine to parse a java.io.Reader. final int parse(char[] buf, T udata) Convenience routine to parse a character array. final Parser<T> plus() Creates a Repeat parser that matches this 1 or more times. final Parser<T> repeat(int min, int max) Creates a Repeat parser that matches this at least min times and not mroe than max times. final Parser<T> repeat(int count) Creates a Repeat parser that matches this exactly count times. static <T> Parser<T> sequence(Parser<? super T> one, Parser<? super T> two, Parser<? super T> three, Parser<? super T> four) Creates a sequence of four parsers. static <T> Parser<T> sequence(Parser<? super T> one, Parser<? super T> two, Parser<? super T> three, Parser<? super T> four, Parser<? super T> five) Creates a sequence of five parsers. static <T> Parser<T> sequence(Parser<? super T> one, Parser<? super T> two, Parser<? super T> three) Creates a Sequence parser from parsers one, two and three sub-parsers. static <T> Parser<T> sequence(Parser<? super T> left, Parser<? super T> right) Creates a Sequence parser from the left and right sub-parsers. final Parser<T> star() Creates a Repeat parser that matches this 0 or more times.
