| Method Summary | |
| public static int[] | computePermutation(Node[] arr1, Node[] arr2)
Compute a permutation between two arrays of nodes. | | static SystemAction[] | createFromNames(String[] arr)
Utility method to remove dependency of this package on
org.openide.actions. | | public static String[] | createPath(Node node, Node parent)
Find a path (by name) from one node to the root or a parent.
Parameters:
node - the node to start in
Parameters:
parent - parent node to stop in (can be null for the root) list of child names--i.e. | | static void | exception(Throwable ex)
Notifies an exception to error manager or prints its it to stderr. | | public static Action[] | findActions(Node[] nodes)
Asks the provided nodes for their actions and those that are common,
to all of them returns. | | public static Node | findChild(Node node, String name)
Look for a node child of given name. | | public static JPopupMenu | findContextMenu(Node[] nodes)
Compute common menu for specified nodes. | | static JPopupMenu | findContextMenuImpl(Node[] nodes, ActionMap actionMap)
Method for finding popup menu for one or more nodes. | | public static Node | findPath(Node start, Enumeration<String> names)
Traverse a path from a parent node down, by an enumeration of names. | | public static Node | findPath(Node start, String[] names)
Traverse a path from a parent node down, by an enumeration of names. | | public static Node | findRoot(Node node)
Find the root for a given node. | | public static Node[] | fromHandles(Node.Handle[] handles)
Takes array of handles and creates array of nodes. | | public static SystemAction[] | getDefaultActions()
Get the default actions for all nodes. | | public static boolean | isSon(Node parent, Node son)
Test whether the second node is a (direct) child of the first one. | | public static void | setDefaultActions(SystemAction[] def)
| | public static Node.Handle[] | toHandles(Node[] nodes)
Takes array of nodes and creates array of handles. | | static void | warning(Throwable ex)
Notifies an exception to error manager or prints its it to stderr. | | public static NodeListener | weakNodeListener(NodeListener l, Object source)
Creates a weak implementation of NodeListener. |
| computePermutation | | public static int[] computePermutation(Node[] arr1, Node[] arr2) throws IllegalArgumentException(Code) | | Compute a permutation between two arrays of nodes. The arrays
must have the same size. The permutation then can be
applied to the first array to create the
second array.
Parameters:
arr1 - first array
Parameters:
arr2 - second array the permutation, or null if the arrays are the same
exception:
IllegalArgumentException - if the arrays cannot be permuted to each other. Eitherthey have different sizes or they do not contain the same elements. |
| createFromNames | | static SystemAction[] createFromNames(String[] arr)(Code) | | Utility method to remove dependency of this package on
org.openide.actions. This method takes names of classes from
that package and creates their instances.
Parameters:
arr - the array of names like "Tools", "Properties", etc. cancontain nulls |
| createPath | | public static String[] createPath(Node node, Node parent)(Code) | | Find a path (by name) from one node to the root or a parent.
Parameters:
node - the node to start in
Parameters:
parent - parent node to stop in (can be null for the root) list of child names--i.e. a path from the parent to the child node
exception:
IllegalArgumentException - if node's getName()method returns null |
| exception | | static void exception(Throwable ex)(Code) | | Notifies an exception to error manager or prints its it to stderr.
Parameters:
ex - exception to notify |
| findActions | | public static Action[] findActions(Node[] nodes)(Code) | | Asks the provided nodes for their actions and those that are common,
to all of them returns.
Parameters:
nodes - array of nodes to compose actions for array of actions for the nodes or empty array if no actionswere found

| findChild | | public static Node findChild(Node node, String name)(Code) | | Look for a node child of given name.
Parameters:
node - node to search in
Parameters:
name - name of child to look for the found child, or null if there is no such child |
| findContextMenu | | public static JPopupMenu findContextMenu(Node[] nodes)(Code) | | Compute common menu for specified nodes.
Provides only those actions supplied by all nodes in the list.
Parameters:
nodes - the nodes the menu for all nodes |
| findContextMenuImpl | | static JPopupMenu findContextMenuImpl(Node[] nodes, ActionMap actionMap)(Code) | | Method for finding popup menu for one or more nodes.
Parameters:
nodes - array of nodes
Parameters:
actionMap - maps keys to actions or null popup menu for this array |
| findPath | | public static Node findPath(Node start, Enumeration<String> names) throws NodeNotFoundException(Code) | | Traverse a path from a parent node down, by an enumeration of names.
Parameters:
start - node to start searching at
Parameters:
names - enumeration of names of nodesalong the path the node with such a path from the start node
exception:
NodeNotFoundException - if the node with such namedoes not exists; the exception contains additional informationabout the failure. |
| findPath | | public static Node findPath(Node start, String[] names) throws NodeNotFoundException(Code) | | Traverse a path from a parent node down, by an enumeration of names.
Parameters:
start - node to start searching at
Parameters:
names - names of nodesalong the path the node with such a path from the start node
exception:
NodeNotFoundException - if the node with such namedoes not exists; the exception contains additional informationabout the failure. |
| findRoot | | public static Node findRoot(Node node)(Code) | | Find the root for a given node.
Parameters:
node - the node its root |
| fromHandles | | public static Node[] fromHandles(Node.Handle[] handles) throws IOException(Code) | | Takes array of handles and creates array of nodes.
Parameters:
handles - array of handles array of nodes
exception:
IOException - if a node cannot be created from the handle |
| getDefaultActions | | public static SystemAction[] getDefaultActions()(Code) | | Get the default actions for all nodes.
array of default actions |
| isSon | | public static boolean isSon(Node parent, Node son)(Code) | | Test whether the second node is a (direct) child of the first one.
Parameters:
parent - parent node
Parameters:
son - son node true if so |
| toHandles | | public static Node.Handle[] toHandles(Node[] nodes)(Code) | | Takes array of nodes and creates array of handles. The nodes that do not
have handles are not included in the resulting array.
Parameters:
nodes - array of nodes array of Node.Handles |
| warning | | static void warning(Throwable ex)(Code) | | Notifies an exception to error manager or prints its it to stderr.
Parameters:
