java.lang.Object

cn.crane4j.core.support.aop.MethodArgumentAutoOperateSupport

public class MethodArgumentAutoOperateSupport
extends Object

Support class for completing the operation of data from the method parameters which annotated by AutoOperate before the method is called.

Before the method is called, the method parameters will be resolved to AutoOperateAnnotatedElement array by AutoOperateAnnotatedElementResolver, and then the AutoOperateAnnotatedElement array will be cached.
When the method is called, the AutoOperateAnnotatedElement array will be used to complete the operation of data from the method parameters.

Support expression for AutoOperate.condition(), if the expression is not empty, the expression will be evaluated by MethodBaseExpressionExecuteDelegate, only when the expression returns true or "true", the operation will be applied.
