Class DVSLContext

java.lang.Object

org.apache.velocity.context.AbstractContext

org.apache.velocity.VelocityContext

org.apache.dvsl.DVSLContext

All Implemented Interfaces:

java.lang.Cloneable, org.apache.velocity.context.Context, org.apache.velocity.context.InternalEventContext

 class DVSLContext
extends org.apache.velocity.VelocityContext

Context implementation that handles wrapping several contexts simultaneously. The style context gets special treatment, getting checked first.
