reverse

public PositionSequence<P> reverse()

Creates a new PositionSequence with positions in reverse order.

Returns:

size

public int size()

Description copied from interface: PositionSequence

Returns the number of Positions contained in this PositionSequence.

Returns:

the number of Positions contained in this PositionSequence.

iterator
