程序包 org.beetl.core.engine

类 GrammarCreator

java.lang.Object

org.beetl.core.engine.GrammarCreator

所有已实现的接口:

IGrammarConstants

public class GrammarCreator
extends Object
implements IGrammarConstants

语法自定义控制，可以集成这个类实现特定扩展 1） 负责提供语法黑名单，则模板不允许出现特定语法，如java直接调用，或者while循环 2） 负责提供功一系列create方法构造语法树，可以重载这些create方法构造自己的语法树,比如，一个允许最多循环10次的while
