Method Details

prev

void prev()

Move the current position one step backwards.

search

void search(IndexUtilities.Comparator comp)

Advances the pointer forward to the last span in the sequence whose interval range has a value v such that comp.directionToTargetFrom(v) >= 0. This operation is O(log(cardinality)). This operation never invalidates a valid cursor, it may only move it forward from its current position but never exhaust it. Note also search should only be called on a non-empty cursor, after having called hasNext() and next() at least once.

Parameters:

comp - a Comparator used to search forward from the current span position.

copy

RspArray.SpanCursorForward copy()

Saner clone.

Returns:

a SpanCursorForward that is a copy of this one.
