Method Detail

### getCell

    public Cell<T> getCell()

  Description copied from interface: `TreeViewModel.NodeInfo`
  Get the `Cell` used to render the children of this node.

  Specified by:
    `getCell` in interface `TreeViewModel.NodeInfo<T>`
  Returns:
    the `Cell`

### getProvidesKey

    public ProvidesKey<T> getProvidesKey()

  Return the key provider for children of this node.

  Specified by:
    `getProvidesKey` in interface `TreeViewModel.NodeInfo<T>`
  Returns:
    the `ProvidesKey`

### getSelectionModel

    public SelectionModel<? super T> getSelectionModel()

  Description copied from interface: `TreeViewModel.NodeInfo`
  Get the `SelectionModel` used for the children of this node. To unify selection across all items of the same type, or across the entire tree, return the same instance of `SelectionModel` from all `TreeViewModel.DefaultNodeInfo`.
