Modifier and Type	Method and Description
void	invalidateLeaf() Notice that the leaf state has changed and that the listener must not assume: (a) that a tuple of interest still resides within the leaf (it may have been moved up or down within the leaf or it may be in another leaf altogether as a result of underflow or overflow); (b) that the leaf is still in use (it may have been discarded by a copy-on-write operation).
