Method Detail

children

public static java.util.Enumeration children(javax.swing.tree.TreeModel model)

Creates and returns an Enumeration across the direct children of the rootNode in the given TreeModel.

Parameters:

model - the TreeModel which contains parent, must not be null

Returns:

an Enumeration across the direct children of the model's root, the enumeration is empty if the root is null or contains no children

children

public static java.util.Enumeration children(javax.swing.tree.TreeModel model,
                                             java.lang.Object parent)

Creates and returns an Enumeration across the direct children of parentNode in the given TreeModel.

Parameters:

model - the TreeModel which contains parent, must not be null

parent - the parent of the enumerated children

Returns:

an Enumeration across the direct children of parent, the enumeration is empty if the parent is null or contains no children
