Interface ExplorerContext

All Known Implementing Classes:

ExplorerContextImpl

public interface 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 visible etc, the context contains ancillary information about the nodes environment.
