Constructor Detail

DataShadow.ShadowNode

public DataShadow.ShadowNode(DataShadow shadow)

Create a shadowing node.

Parameters:

shadow - the shadow

Method Detail

cloneNode

public Node cloneNode()

Description copied from class: FilterNode

Create new filter node for the original. Subclasses do not have to override this, but if they do not, the default implementation will filter the subclass filter, which is not very efficient.

Overrides:

cloneNode in class FilterNode

Following copied from class: org.openide.nodes.FilterNode

Returns:

copy of this node

setName

public void setName(String name)

Description copied from class: Node

Set the system name. Fires a property change event.

Overrides:

setName in class FilterNode

Following copied from class: org.openide.nodes.Node

Parameters:

s - the new name

Throws:

IllegalArgumentException - if the new name cannot represent a valid node name

getName

public String getName()

The name of the shadow.

Overrides:

getName in class FilterNode

Returns:

the name

getDisplayName

public String getDisplayName()

Overrides:

getDisplayName in class FilterNode

getShortDescription

public String getShortDescription()

Overrides:

getShortDescription in class FilterNode

getIcon

public Image getIcon(int type)

Description copied from class: Node

Find an icon for this node (in the closed state).

Overrides:

getIcon in class FilterNode

Following copied from class: org.openide.nodes.Node

Parameters:

type - constant from BeanInfo

Returns:

icon to use to represent the node

getOpenedIcon

public Image getOpenedIcon(int type)

Description copied from class: Node

Find an icon for this node (in the open state). This icon is used when the node may have children and is expanded.

Overrides:

getOpenedIcon in class FilterNode

Following copied from class: org.openide.nodes.Node

Parameters:

type - constant from BeanInfo

Returns:

icon to use to represent the node when open

canDestroy

public boolean canDestroy()

Description copied from class: Node

Test whether this node can be deleted.

Overrides:

canDestroy in class FilterNode

Following copied from class: org.openide.nodes.Node

Returns:

true if can

destroy

public void destroy()
             throws IOException

Description copied from class: Node

Remove the node from its parent and deletes it. The default implementation obtains write access to the children's lock, and removes the node from its parent (if any). Also fires a property change.

This may be overridden by subclasses to do any additional cleanup.

Overrides:

destroy in class FilterNode

Following copied from class: org.openide.nodes.Node

Throws:

IOException - if something fails

canRename

public final boolean canRename()

Description copied from class: Node

Test whether this node can be renamed. If true, one can use FeatureDescriptor.getName() to obtain the current name and Node.setName(java.lang.String) to change it.

Overrides:

canRename in class FilterNode

Returns:

true if shadow can be renamed

canCopy

public final boolean canCopy()

Description copied from class: Node

Test whether this node permits copying.

Overrides:

canCopy in class FilterNode

Following copied from class: org.openide.nodes.Node

Returns:

true if so

canCut

public final boolean canCut()

Description copied from class: Node

Test whether this node permits cutting.

Overrides:

canCut in class FilterNode

Following copied from class: org.openide.nodes.Node

Returns:

true if so

getCookie

public Node.Cookie getCookie(Class cl)

Description copied from class: Node

Get a cookie for this node.

The set of cookies can change. If a node changes its set of cookies, it fires a property change event with Node.PROP_COOKIE.

Overrides:

getCookie in class FilterNode

Following copied from class: org.openide.nodes.Node

Parameters:

type - the representation class of the cookie

Returns:

a cookie assignable to that class, or null if this node has no such cookie

getPropertySets

public Node.PropertySet[] getPropertySets()

Returns modified properties of the original node.

Overrides:

getPropertySets in class FilterNode

Returns:

property sets

clipboardCopy

public Transferable clipboardCopy()
                           throws IOException

Copy this node to the clipboard.

Overrides:

clipboardCopy in class FilterNode

Returns:

ExTransferable.Single with one copy flavor

Throws:

IOException - if it could not copy

See Also:

NodeTransfer

clipboardCut

public Transferable clipboardCut()
                          throws IOException

Cut this node to the clipboard.

Overrides:

clipboardCut in class FilterNode

Returns:

ExTransferable.Single with one cut flavor

Throws:

IOException - if it could not cut

See Also:

NodeTransfer

drag

public Transferable drag()
                  throws IOException

This implementation only calls clipboardCopy supposing that copy to clipboard and copy by d'n'd are similar.

Overrides:

drag in class FilterNode

Returns:

transferable to represent this node during a drag

Throws:

IOException - when the cut cannot be performed

createNodeListener

protected NodeListener createNodeListener()

Creates a node listener that allows listening on the original node and propagating events to the proxy.

Intended for overriding by subclasses, as with FilterNode.createPropertyChangeListener().

Overrides:

createNodeListener in class FilterNode

Returns:

a FilterNode.NodeAdapter in the default implementation

equals

public boolean equals(Object o)

Equal if the o is ShadowNode to the same shadow object.

Overrides:

equals in class FilterNode

Following copied from class: org.openide.nodes.FilterNode

Parameters:

o - something to compare to, presumably a node or FilterNode of one

Returns:

true if this node's original node is the same as the parameter (or original node of parameter)

hashCode

public int hashCode()

Hashcode is computed by the represented shadow.

Overrides:

hashCode in class FilterNode

Following copied from class: org.openide.nodes.FilterNode

Returns:

the delegated hash code
