public class EvaluateContext
extends ChainedInternalContextAdapter

This is a special, internal-use-only context implementation to be used for the #evaluate directive. We use this context to chain the existing context, preventing any changes from impacting the parent context. By separating this context into a separate class it also allows for the future possibility of changing the context behavior for the #evaluate directive. Note that the context used to store values local to #evaluate() is user defined but defaults to VelocityContext.

Allows callers to explicitly put objects in the local context. Objects added to the context through this method always end up in the top-level context of possible wrapped contexts.

指定者:

localPut 在接口中 InternalWrapperContext

覆盖:

localPut 在类中 ChainedInternalContextAdapter

参数:

key - name of item to set.

value - object to set to key.

返回:
