Method Detail

invalidate

public void invalidate()

getUniqueID

public java.lang.Object getUniqueID(javax.swing.tree.TreePath path)

Description copied from interface: Identifiable

Returns an unique identifier for the specified path if applicable. This method is usually used to store a tree state on disposing, so we cannot use invoker to calculate it later on a valid thread, and an implementor must be ready to support any thread.

Specified by:

getUniqueID in interface Identifiable

Parameters:

path - a tree path in the current tree model

Returns:

an unique identifier for the specified path, or null if not applicable

getInvoker

public Invoker getInvoker()

Specified by:

getInvoker in interface InvokerSupplier

Returns:

preferable invoker to be used to access the supplier

getRoot

public final java.lang.Object getRoot()

Specified by:

Specified by:

getChild in interface javax.swing.tree.TreeModel

getChildCount

public final int getChildCount(java.lang.Object object)

Specified by:

getChildCount in interface javax.swing.tree.TreeModel

isLeaf
