BaseNode

@Deprecated
public BaseNode(GridTreeModel model,
                           Node parent,
                           AsyncClient asyncClient,
                           MessageAdapter messageAdapter)

Deprecated.

BaseNode

public BaseNode(GridTreeModel model,
                Node parent,
                AsyncClient asyncClient,
                MessageProvider messageProvider)

Method Detail

notifyNodeChanged

public void notifyNodeChanged()

Send the notification to the listeners of the node state (not including the children change listeners)

requestChildren

public abstract void requestChildren()

Get the child nodes. This method is called whenever child nodes must be updated. The implementation should modify (if necessary) the child list with setChildren(List) method.

requestContents

public abstract void requestContents()

Get the contents of the node. This may be not children nodes but some other information.

refresh

public void refresh()

Refresh the list of the children. After the refresh is completed the listeners are invoked.

getChildren

public java.util.List<Node> getChildren()

Get the currently cached list of the children. If the list is null then a children request is started and an empty list is returned.

Returns:

the list of the children. May be empty (not null!) if no children cached.

getContents

public java.util.List getContents()

Get the currently cached contents of the node. If the contents list is null then the request of the contents is invoked.

Returns:

the contents

setChildren

public void setChildren(java.util.List<Node> children)

Set the child nodes.

Parameters:

children - new child node list

setContents

public void setContents(java.util.List contents)

Set the contents

Parameters:

contents - - the contents

addChildrenChangeListener

public void addChildrenChangeListener(ChildrenChangeListener l)

Add the listener of changes in the list of the children

Parameters:

l - - the listener

removeChildrenChangeListener

public void removeChildrenChangeListener(ChildrenChangeListener l)

Remove the listener of changes in the list of the children

Parameters:

l - - the listener

notifyContentsChangeListener

public void notifyContentsChangeListener(java.util.List contents)

addContentsChangeListener

public void addContentsChangeListener(ContentsChangeListener listener)

removeContentsChangeListener

public void removeContentsChangeListener(ContentsChangeListener listener)

getChildCount

public int getChildCount()

Description copied from interface: Node

Get the number of children nodes.

Specified by:

getChildCount in interface Node

Returns:

The number of children

getChild

public Node getChild(int i)

Description copied from interface: Node

Get the child specified with the index.

Specified by:

getChild in interface Node

Parameters:

i - The index of the child to get

Returns:

The child node

getPath

public java.lang.Object[] getPath()

Description copied from interface: Node

Get the path to the node.

Specified by:

getPath in interface Node

Returns:

the array representing the path to the node

getModel

public GridTreeModel getModel()

Get the tree model.

Returns:

the tree model

executeRequest

public void executeRequest(Request request,
                           com.intel.gpe.util.observer.IObserver observer)

getAsyncClient

public AsyncClient getAsyncClient()

showException

public void showException(java.lang.String message,
                          java.lang.Throwable e)

getMessageAdapter

@Deprecated
public MessageAdapter getMessageAdapter()

Deprecated. use getMessageProvider() instead

Returns:

getMessageProvider

public MessageProvider getMessageProvider()

setModel

public void setModel(GridTreeModel model)

getIconPath

public java.lang.String getIconPath()

Specified by:

getIconPath in interface ObjectWithIcon

getIndex

public int getIndex(Node node)

Description copied from interface: Node

Get the index of the child. If the specified node is not the child of this one then -1 is returned.

Specified by:

getIndex in interface Node

Parameters:

node - - the node

Returns:

the index of the node. -1 if the node is not contained in the receiver.

compareTo

public int compareTo(Node node)

Specified by:

compareTo in interface java.lang.Comparable<Node>
