RangeIterator

RangeIterator is a wrapper over MutableS2ShapeIndex::Iterator with extra methods that are useful for merging the contents of two or more S2ShapeIndexes.

class RangeIterator {

this(MutableS2ShapeIndex index);

S2CellId id();

const(S2ShapeIndexCell) cell();

S2CellId rangeMin();

S2CellId rangeMax();

const(S2ClippedShape) clipped();

int numEdges();

bool containsCenter();

void next();

bool done();

void seekTo(RangeIterator target);

void seekBeyond(RangeIterator target);

}

Constructors

this this(MutableS2ShapeIndex index): Construct a new RangeIterator positioned at the first cell of the index.

Functions

cell const(S2ShapeIndexCell) cell(): Undocumented in source. Be warned that the author may not have intended to support it.
clipped const(S2ClippedShape) clipped(): Various other convenience methods for the current cell.
containsCenter bool containsCenter(): Undocumented in source. Be warned that the author may not have intended to support it.
done bool done(): Undocumented in source. Be warned that the author may not have intended to support it.
id S2CellId id(): The current S2CellId and cell contents.
next void next(): Undocumented in source. Be warned that the author may not have intended to support it.
numEdges int numEdges(): Undocumented in source. Be warned that the author may not have intended to support it.
rangeMax S2CellId rangeMax(): Undocumented in source. Be warned that the author may not have intended to support it.
rangeMin S2CellId rangeMin(): The min and max leaf cell ids covered by the current cell. If Done() is true, these methods return a value larger than any valid cell id.
seekBeyond void seekBeyond(RangeIterator target): Positions the iterator at the first cell that follows "target", i.e. the first cell such that range_min() > target.range_max().
seekTo void seekTo(RangeIterator target): Positions the iterator at the first cell that overlaps or follows "target", i.e. such that range_max() >= target.range_min().
