Class SourceChildren

java.lang.Object
  org.openide.nodes.Children

All Implemented Interfaces:

Cloneable, FilterCookie, Node.Cookie

---

public class SourceChildren
extends Children.Keys
implements FilterCookie

Normal implementation of children for source element nodes.

Ordering and filtering of the children can be customized using SourceElementFilter. FilterCookie is implemented to provide a means for user customization of the filter.

The child list listens to changes in the source element, as well as the filter, and automatically updates itself as appropriate.

A child factory can be used to cause the children list to create non-default child nodes, if desired, both at the time of the creation of the children list, and when new children are added.

The children list may be unattached to any source element temporarily, in which case it will have no children (except possibly an error indicator).

Field Detail

element

protected SourceElement element

The element whose subelements are represented.

---

filter

protected SourceElementFilter filter

Filter for elements. Can be null, in which case modifier filtering is disabled, and ordering may be reset to the default order.

---

factory

protected ElementNodeFactory factory

Factory for obtaining class nodes.

Constructor Detail

SourceChildren

public SourceChildren()

Create a children list with the default factory and no attached source element.

---

SourceChildren

public SourceChildren(SourceElement element)

Create a children list with the default factory.

Parameters:

element - source element to attach to, or null

---

SourceChildren

public SourceChildren(ElementNodeFactory factory)

Create a children list with no attached source element.

Parameters:

factory - a factory for creating children

---

SourceChildren

public SourceChildren(ElementNodeFactory factory,
                      SourceElement element)

Create a children list.

Parameters:

factory - a factory for creating children

element - source element to attach to, or null

Method Detail

getFilterClass

public Class getFilterClass()

Specified by:

getFilterClass in interface FilterCookie

---

getFilter

public Object getFilter()

Specified by:

getFilter in interface FilterCookie

---

setFilter

public void setFilter(Object filter)

Specified by:

setFilter in interface FilterCookie

---

addNotify

protected void addNotify()

Overrides:

addNotify in class Children

---

removeNotify

protected void removeNotify()

Overrides:

removeNotify in class Children

---

createNodes

protected Node[] createNodes(Object key)

Specified by:

createNodes in class Children.Keys

---

getNodes

public Node[] getNodes(boolean initialize)

If `initialize' is true, invokes the parser and waits for it to finish. If false, it just returns whatever nodes are available right now.

Overrides:

getNodes in class Children

Returns:

array of nodes after the Children are fully initialized

---

findChild

public Node findChild(String name)

Overrides:

findChild in class Children

---

getElement

public SourceElement getElement()

Get the currently attached source element.

Returns:

the element, or null if unattached

---

setElement

public void setElement(SourceElement element)

Set a new source element to get information about children from.

Parameters:

element - the new element, or null to detach
