Method Details

canPromote

boolean canPromote(Collection<TreePath> pPaths)

canDemote

boolean canDemote(Collection<TreePath> pPaths)

canMoveUp

boolean canMoveUp(Collection<TreePath> pPaths)

canMoveDown

boolean canMoveDown(Collection<TreePath> pPaths)

promote

void promote(Collection<TreePath> pPaths)
      throws RearrangeableTreeModel.IllegalNodeMoveException

Move nodes one level closer to the root. All children should be promoted along with the parent. If pPaths includes both a path and a sub-path, the former promotion occurs first.

A B C D E F G
Promote[AD]	Promote [AD, ADF]
A B C D E F G	A B C D E G F

Parameters:

pPaths - Paths to be moved.

Throws:

UnsupportedOperationException - If implementor does not allow promotions.

RearrangeableTreeModel.IllegalNodeMoveException

demote

void demote(Collection<TreePath> pPaths)
     throws RearrangeableTreeModel.IllegalNodeMoveException

Move nodes one level further from the root. If pPaths includes both a path and a sub-path, the former promotion occurs first.

Parameters:

pPaths - Paths to be moved.

Throws:

UnsupportedOperationException - If implementor does not allow promotions.

RearrangeableTreeModel.IllegalNodeMoveException

moveUp

void moveUp(Collection<TreePath> pPaths)
     throws RearrangeableTreeModel.IllegalNodeMoveException

Move nodes one space higher (swap with predecessors).

Parameters:

pPaths - Paths to be moved.

Throws:

UnsupportedOperationException - If implementor does not allow promotions.

RearrangeableTreeModel.IllegalNodeMoveException

moveDown

void moveDown(Collection<TreePath> pPaths)
       throws RearrangeableTreeModel.IllegalNodeMoveException

Move nodes one space lower (swap with successors).

Parameters:

pPaths - Paths to be moved.

Throws:

UnsupportedOperationException - If implementor does not allow promotions.
