Method Detail

children

java.util.Enumeration children()

Returns the children of this node in an Enumeration. If this object does not have children, it should return an empty Enumeration, not null. All objects contained in the Enumeration should implements TMNode.

Returns:

an Enumeration containing childs of this node

isLeaf

boolean isLeaf()

Checks if this node is a leaf or not. A node could have no children and still not be a leaf.

Returns:

true if this node is a leaf; false otherwise

setUpdater

void setUpdater(TMUpdater updater)

Called by the TMUpdater constructor. Gives to this node a reference to a TMUpdater object. This node should use this reference to notify treemap that something has changed. See the differents update methods of the TMUpdater interface.

As this method is called by the constructor of TMUpdater, don't call methods of TMUpdater in this method.

Parameters:

updater - the TMUpdater to be called when something has changed
