org.apache.velocity.tools.view.context.ViewContext

Objects implementing this interface are passed to view tools upon initialization by the {@link org.apache.velocity.tools.view.servlet.ServletToolboxManager}.

The interface provides view tools in a servlet environment access to relevant context information, like servlet request, servlet context and the velocity context.
