包路径：groovy.lang.GroovyClassLoader
类名称：GroovyClassLoader
方法名：getTimeStamp

GroovyClassLoader.getTimeStamp介绍

[英]gets the time stamp of a given class. For groovy generated classes this usually means to return the value of the static field __timeStamp. If the parameter doesn't have such a field, then Long.MAX_VALUE is returned
[中]获取给定类的时间戳。对于groovy生成的类，这通常意味着返回静态字段\uuu timeStamp的值。如果参数没有这样的字段，则为Long。返回最大值

/**

 * will try to locate a groovy source file for this class and then compile it again,
 * adding the resulting class as entry to the cache. Giving null as class is like a
 * recompilation, so the method should always return true here. Only classes that are
 * implementing GroovyObject are compilable and only if the timestamp in the class
 * is lower than Long.MAX_VALUE.
 * <p>
 * NOTE: First the parent loaders will be asked and only if they don't return a
 * class the recompilation will happen. Recompilation also only happen if the source
 * file is newer.
 *
 * @param cls the class to be tested. If null the method should return true
 * @return true if the class should be compiled again
