Region.TaggedInterval

intersects bool intersects(in TaggedInterval other): Returns true iff the tagged intervals intersect.
isStrictlyAfter bool isStrictlyAfter(in TaggedInterval other): Returns true iff the tagged intervals do not intersect and this > other.
isStrictlyBefore bool isStrictlyBefore(in TaggedInterval other): Returns true iff the tagged intervals do not intersect and this < other.
opBinary TaggedInterval opBinary(in TaggedInterval other): Returns the intersection of both intervals; empty if tags differ.
opBinary Region opBinary(in TaggedInterval other): Returns the difference of both intervals.
opBinary bool opBinary(in TaggedInterval other): Returns true iff this is a subset of other, ie. fully included _in_.
opOpAssign TaggedInterval opOpAssign(in TaggedInterval other): Returns the intersection of both intervals; empty if tags differ.

Properties

empty bool empty [@property getter]: Returns true iff the interval is empty. An interval is empty iff begin == end.
size Number size [@property getter]: Returns the size of this interval.

Static functions

convexHull TaggedInterval convexHull(in TaggedInterval[] intervals...): Returns the convex hull of the intervals.

Examples

1 static enum emptyTag = 42;
2 alias R = Region!(int, int, "bucketId", emptyTag);
3 alias TI = R.TaggedInterval;
4 
5 TI emptyInterval;
6 
7 // Default constructor produces empty interval.
8 assert((emptyInterval).empty);
9 assert(emptyInterval.tag == emptyTag);
10 
11 auto ti1 = TI(1, 0, 10);
12 
13 // The tag can be aliased:
14 assert(ti1.tag == ti1.bucketId);
15 
16 auto ti2 = TI(1, 5, 15);
17 
18 // Tagged intervals with the same tag behave like regular intervals:
19 assert((ti1 & ti2) == TI(1, 5, 10));
20 
21 auto ti3 = TI(2, 0, 10);
22 
23 // Tagged intervals with different tags are distinct:
24 assert((ti1 & ti3).empty);
