Package Exports

interval-tree

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-tree) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

itree.add([22, 56,  'foo']);
itree.add([44, 199, 'bar']);

// search 1: get overlapped regions from one point
var results = itree.search(103);

results.forEach(function(result) {
  console.log(result.data); // overlapped range data
  console.log(result.id);   // id of the overlapped range
});

// search 2: get overlapped regions from a range
var results2 = itree.search(103, 400);

results2.forEach(function(result) {
  console.log(result.data);  // overlapped range data
  console.log(result.id);    // id of the overlapped range
  console.log(result.rate1); // overlapped rate to the given range
  console.log(result.rate2); // overlapped rate to the range of this result
});
