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

require

var IntervalTree = require('interval-tree2');

when using in web, use dist/interval-tree.js in this module.

<script src="dist/interval-tree.js"></scirpt>

create

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

add interval data

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
itree.add(1, 38); // id is automatically set when not given

search by point: get overlapped intervals from one point

var intervals = itree.search(103);

var intervals = itree.pointSearch(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 by range: get overlapped intervals from a range

var intervals2 = itree.search(103, 400);

var intervals2 = itree.rangeSearch(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
});

remove an interval by id

itree.remove('foo');
