Implementation of the parsing features.

There is a newer version: 3.2

package fr.vergne.parsing.layer.impl;

import fr.vergne.parsing.layer.Layer;

/**
 * A {@link GreedyMode} is a decorator which is added to some specific formats
 * of {@link Layer}s. For instance, for a {@link Layer} equivalent to a regex
 * wildcard like X*, it is possible to optimize the regex computation by making
 * it greedy (default), lazy (add '?') or possessive (add '+'). You can find
 * plenty of information about these different optimizations on the web, so no
 * detail is given here. However, this management was introduced on the fly and
 * should be revised in order to have a clean use of such features.
