Class DVSLNodeContext

  • All Implemented Interfaces:
    java.lang.Cloneable, org.apache.velocity.context.Context, org.apache.velocity.context.InternalEventContext
    class DVSLNodeContext
extends org.apache.velocity.VelocityContext

    Context implementation that is the outer context during the transformation. Holds the node stack and also protects the 'special' context elements like 'node'

    There are special elements like 'node', which is readonly and corresponds to the current node, and 'attrib', which corresponds to a map of attributes for the current node.
