PwkTreeModel

public PwkTreeModel(javax.swing.tree.TreeNode root)

Method Detail

isNameUnique

public static boolean isNameUnique(java.util.Enumeration nodes,
                                   PwkTreeNode currentNode,
                                   java.lang.String name)

Check a node for uniqueness of its name.

Parameters:

nodes - an enumeration of nodes to compare against for uniqueness

currentNode - the current node - this is needed because a node having the same name as itself is considered unique

name - the name to check for uniqueness

Returns:

true if name is unique within nodes (with the exception of currentNode), false if not

getRootNode

public PwkTreeNode getRootNode()

isCategoryNameUnique

public boolean isCategoryNameUnique(PwkTreeNode currentNode,
                                    java.lang.String categoryName)

Checks if the category name is unique.

Parameters:

currentNode - the category node

categoryName - the category name

Returns:

true if the name is unique, false if not

isItemNameUnique

public boolean isItemNameUnique(PwkTreeNode catNode,
                                PwkTreeNode itemNode,
                                java.lang.String itemName)

Checks if the item name is unique within its category.

Parameters:

catNode - the category node

itemNode - the item node

itemName - the item name

Returns:

true if the name is unique within catNode, false if not

sort

public void sort()

Sorts the tree by sorting the children of each node recursively.
