Interface Vec2Iterator
- All Known Implementing Classes:
- DFLIC.ElementIterator, RandomGridIterator, ScanlineGridIterator
- public interface Vec2Iterator
Interface for producing a sequence of points on a plane.
This interface is mostly used to iterate over a set of points in
a field. For example, ScanlineGridIterator produces the sequence of
integer points going left-right, top-down in scanline order, while
RandomGridIterator produces pseudo-random points that cover a
rectangular region.

Method Summary |
Vec2 |
next()
Returns: null if there are no more points in the sequence, else
a Vec2 whose value is the next point. |
next
public Vec2 next()
- Returns: null if there are no more points in the sequence, else
a Vec2 whose value is the next point. The returned Vec2
may be modified by the caller. The same Vec2 may be
written to again on the subsequent call to next().
