类 EmptyContainer

java.lang.Object

cn.crane4j.core.container.EmptyContainer

所有已实现的接口:

Container<Object>, LimitedContainer<Object>

public class EmptyContainer
extends Object
implements LimitedContainer<Object>

An empty data source container for placeholders, it does not provide any data and data registration function itself.
When an assembly operation specifies to use the data source container, it actually means that the operation object itself will be used as the data source object.
