Interface AsyncTreeDataUpdater<N extends AsyncUniqueNode>

Type Parameters:

N - node type

public interface AsyncTreeDataUpdater<N extends AsyncUniqueNode>

This interface provides methods for asynchronous tree data update. Basically these methods called when some tree node is renamed, moved or removed. This interface will be informed about such changes so you can perform data update actions.

Method Detail

nodesAdded

void nodesAdded(List<N> nodes,
                N parentNode,
                Runnable rollback)

Called when nodes add operation performed. At this point nodes are already added visually, but you can still cancel this action if you cannot update data properly.

Parameters:

nodes - added nodes list

parentNode - parent node where specified nodes were added

rollback - runnable you should call in case data update failed, it will cancel changes

nodeRenamed

void nodeRenamed(N node,
                 String oldName,
                 String newName,
                 Runnable rollback)

Called when node rename operation performed. At this point node is already renamed visually, but you can still cancel this action if you cannot update data properly.

Parameters:

node - renamed node

oldName - old node name

newName - new node name

rollback - runnable you should call in case data update failed, it will cancel changes

nodesMoved

void nodesMoved(List<N> nodes,
                N oldParent,
                N newParent,
                Runnable rollback)

Called when node move (D&D or cut/paste) operation performed. At this point nodes are already moved visually, but you can still cancel this action if you cannot update data properly.

Parameters:

nodes - moved nodes list

oldParent - old parent node

newParent - new parent node

rollback - runnable you should call in case data update failed, it will cancel changes

nodesCopied

void nodesCopied(List<N> nodes,
                 N oldParent,
                 N newParent,
                 Runnable rollback)

Called when node copy (D&D or copy/paste) operation performed. At this point nodes are already copied visually, but you can still cancel this action if you cannot update data properly.

Parameters:

nodes - moved nodes list

oldParent - old parent node

newParent - new parent node

rollback - runnable you should call in case data update failed, it will cancel changes

nodesRemoved

void nodesRemoved(List<N> nodes,
                  Runnable rollback)

Called when nodes remove operation performed. At this point nodes are already removed visually, but you can still cancel this action if you cannot update data properly.

Parameters:

nodes - removed nodes list

rollback - runnable you should call in case data update failed, it will cancel changes
