Class: IntSpanSet ​

Defined in: core/types/collections/number/IntSpanSet.ts:30

An ordered set of disjoint IntSpan values.

Example ​

ts
const ss = IntSpanSet.fromString('{[1, 5), [8, 12)}');
console.log(ss.numSpans()); // 2
console.log(ss.lower());    // 1
console.log(ss.upper());    // 12
ss.free();
