Class EvaluateContext

java.lang.Object

bboss.org.apache.velocity.context.ChainedInternalContextAdapter

bboss.org.apache.velocity.context.EvaluateContext

All Implemented Interfaces:

Context, InternalContextAdapter, InternalEventContext, InternalWrapperContext

Deprecated.

Will be removed in 2.0

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.

Since:

1.6
