Package Exports

interval-tree2

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (interval-tree2) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

usage

// add interval data

var itree = new IntervalTree(300); // 300 : the center of the tree

itree.add(22, 56,  'foo'); // 'foo' is the id of the interval data
itree.add(44, 199, 'bar'); // 'bar' is the id of the interval data

// search 1: get overlapped intervals from one point (See Interval class)
var intervals = itree.search(103);

intervals.forEach(function(interval) {
  console.log(interval.start); // overlapped interval start position
  console.log(interval.end);   // overlapped interval end position
  console.log(interval.id);    // id of the overlapped interval
});

// search 2: get overlapped regions from a range
var intervals2 = itree.search(103, 400);

intervals2.forEach(function(interval) {
  console.log(interval.start); // overlapped interval start position
  console.log(interval.end);   // overlapped interval end position
  console.log(interval.id);    // id of the overlapped interval
});
