org.oddjob.monitor.model.ExplorerContextImpl

All Implemented Interfaces:

ExplorerContext

public class ExplorerContextImpl
extends java.lang.Object
implements ExplorerContext

Explorer Context. Used to pass useful things down the job hierarchy.

A unique context will exist for each node in the hierarchy but where as the model has specific information about the node in the tree - it's children, is it visable etc, the context contains ancillary informaton about the nodes environment.
