Constructor Detail

ClassChildren

public ClassChildren(ClassElement element)

Create class children with the default factory. The children are initially unfiltered.

Parameters:

element - attached class element (non-null)

ClassChildren

public ClassChildren(ElementNodeFactory factory,
                     ClassElement element)

Create class children. The children are initially unfiltered.

Parameters:

factory - the factory to use to create new children

element - attached class element (non-null)

Method Detail

getFilterClass

public Class getFilterClass()

Implementation of filter cookie

Specified by:

getFilterClass in interface FilterCookie

Following copied from interface: org.openide.cookies.FilterCookie

Returns:

the class, or may be null if no filter is currently in use

getFilter

public Object getFilter()

Description copied from interface: FilterCookie

Get the current filter.

Specified by:

getFilter in interface FilterCookie

Following copied from interface: org.openide.cookies.FilterCookie

Returns:

the filter, or null if none is currently in use

setFilter

public void setFilter(Object filter)

Description copied from interface: FilterCookie

Set the current filter.

Specified by:

setFilter in interface FilterCookie

Following copied from interface: org.openide.cookies.FilterCookie

Parameters:

filter - the filter, or null if none should be used

addNotify

protected void addNotify()

Description copied from class: Children

Called when children are first asked for nodes. Typical implementations at this time calculate their node list (or keys for Children.Keys etc.).

Overrides:

addNotify in class Children

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

See Also:

Children.isInitialized()

removeNotify

protected void removeNotify()

Description copied from class: Children

Called when the list of nodes for this children object is no longer needed by the IDE. Typical implementations at this time remove all children to save memory (or clear the keys for Children.Keys etc.).

Overrides:

removeNotify in class Children

createNodes

protected Node[] createNodes(Object key)

Description copied from class: Children.Keys

Create nodes for a given key.

Overrides:

createNodes in class Children.Keys

Following copied from class: org.openide.nodes.Children.Keys

Parameters:

key - the key

Returns:

child nodes for this key or null if there should be no nodes for this key

refreshAllKeys

protected void refreshAllKeys()

Updates all the keys (elements) according to the current filter & ordering.

refreshKeys

protected void refreshKeys(int filter)

Updates all the keys with given filter.

getKeysOfType

protected Collection getKeysOfType(int elementType)

Filters and returns the keys of specified type.

getOrder

protected int[] getOrder()

Returns order form filter.
