Description copied from interface: WeakExplorerNode

This method is called by ExplorerTreeModel to check if this WeakExplorerNode subsumes another WeakExplorerNode, ie if this node should be preserved rather than adding the other node.

This relation should be reflexive, so that if a is a WeakExplorerNode then a.subsumes(a) == true.

This relation should be symmetric, so that if a and b are WeakExplorerNodes and a.subsumes(b) == true then b.subsumes(a) == true.

This relation should be transitive, so that if a, b and c are WeakExplorerNodes, a.subsumes(b) == true and b.subsumes(c) == true then a.subsumes(c) == true.

Note: While this means that only other WeakExplorerNodes can be subsumed, the argument is still of Object type. This is just since there is no particular point in getting a WeakExplorerNode reference, you would either have to down-cast it further or wouldn't use it more than as an Object pointer.

Specified by:

subsumes in interface WeakExplorerNode

Parameters:

obj - another WeakExplorerNode

Returns:

true if this node subsumes obj, otherwise false.
