Class ExplorerContext

java.lang.Object
oracle.ide.explorer.ExplorerContext

public final class ExplorerContext

extends java.lang.Object

The ExplorerContext class is a utility class that can be used to get at the extra data the ExplorerWindow stores in the the Context.

This class also contains helpful methods to store and restore the expansion state of nodes in a tree explorer.

Nested Class Summary
