接口 Context<K,V>

所有超级接口:

Map<K,V>

所有已知实现类:

ContextMap

public interface Context<K,V>
extends Map<K,V>

执行上下文，用来在不同的Command间传递信息。 Map后面可以考虑使用AttributeMap代替。

retrieve

<T extends V> T retrieve(K key)

That method enhances the Map.get(Object) method that helps users avoid the redundant code of type cast/checking when assignments are already known.

It throws ClassCastException if types are not assignable.

类型参数:

T - the target assignment type

参数:

key - the key whose associated value is to be returned

返回:

the value to which the specified key is mapped, or null if this map contains no mapping for the key
