Constructor Detail

AbstractTreeNodeVisitor

public AbstractTreeNodeVisitor(java.util.function.Supplier<? extends T> supplier,
                               java.util.function.Predicate<? super javax.swing.tree.TreePath> predicate)

Parameters:

supplier - that provides an element to search in a tree

predicate - that controls visiting children of found node: null to interrupt visiting, true to continue visiting with children, false to continue visiting without children

Method Detail

getElement

public final T getElement()

Returns:

an element to search in a tree or null if it is obsolete

visit

public TreeVisitor.Action visit(javax.swing.tree.TreePath path)

Specified by:

visit in interface TreeVisitor

Parameters:

path - a currently visited path

Returns:

an action that controls visiting a tree

visit

protected TreeVisitor.Action visit(javax.swing.tree.TreePath path,
                                   AbstractTreeNode node,
                                   T element)

Parameters:

path - a currently visited path

node - a node of a tree structure

element - an element to find

Returns:

an action that controls visiting a tree

matches

protected boolean matches(AbstractTreeNode node,
                          T element)

Parameters:

node - a node of a tree structure

                           T element)

Parameters:

node - a node of a tree structure

Returns:

true if the specified node is an ancestor of the given element

getContent

protected T getContent(AbstractTreeNode node)

Parameters:

node - a node of a tree structure

Returns:

a content of the specified tree or null

isAncestor

protected boolean isAncestor(T content,
                             T element)

Parameters:

content - a content of a tree node

element - an element to find

Returns:

true if the specified content is an ancestor of the given element
