类 MethodInvokerContainer

java.lang.Object

cn.crane4j.core.container.MethodInvokerContainer

所有已实现的接口:

Container<Object>

直接已知子类:

MethodInvokerContainer.SingleKey, MethodInvokerContainer.StandardMethodInvokerContainer

public abstract class MethodInvokerContainer
extends Object
implements Container<Object>

Method data source container, specify any method without parameters or the first parameter is Collection type method, and adapt it to a data source container.

This container is generally not created directly by users, but is used in conjunction with MethodInvokerContainerCreator to scan the methods in a large number of specific context objects in the framework according to annotations or specific configurations, automatically adapt them to data source containers and register them.

If only a few known methods need to be used as data sources, you can directly use LambdaContainer.
