Interface UiWidgetAbstractTree.UiTreeModelMutable<NODE>

Type Parameters:

NODE - is the generic type of the tree-nodes of this model.

All Superinterfaces:

UiWidgetAbstractTree.UiTreeModel<NODE>

All Known Implementing Classes:

UiTreeNodeModel

Enclosing interface:

UiWidgetAbstractTree<NODE>

public static interface UiWidgetAbstractTree.UiTreeModelMutable<NODE>
extends UiWidgetAbstractTree.UiTreeModel<NODE>

Extends UiWidgetAbstractTree.UiTreeModel with features for editing the tree structure. It represents the current state of the tree for a tree widget. Modifications may still be cancelled and reverted.
ATTENTION:
Implementing a mutable tree model is not always easy. The suggested approach is to create a copy of each tree node that can be modified by the tree widget without causing harm. Central caching of tree nodes from the server can be done based on a central and immutable UiWidgetAbstractTree.UiTreeModel used by the according mutable tree models.

Method Detail

addChild

void addChild(NODE parent,
              NODE child,
              int index)

Adds the given child <NODE> to the given parent at the specified index.

Parameters:

parent - is the parent <NODE> where to add the given child.

child - is the <NODE> to add to the children of parent. This method will remove the child from any previous parent. The instance of the child may later be modified. To prevent undesired modifications create a deep-copy of the node before calling this method.

index - is the index where to add the child.

addChild

void addChild(NODE parent,
              NODE child)

Convenience method variant of addChild(Object, Object, int) to add a child at the end.

Parameters:

parent - is the parent <NODE> where to add the given child.

child - is the <NODE> to add to the children of parent.

addChild(Object, Object, int)

removeChilden

void removeChilden(NODE parent,
                   NODE... children)

Removes the given children from the parent.

Parameters:

parent - is the parent <NODE> where to remove the given children.

children - are the children to remove.
