API

import

Creates an interval tree

import createIntervalTree from 'interval-tree';

const tree = createIntervalTree();

insert(low, high, id)

Inserts an interval into the tree

tree.insert(10, 15, '123');

remove(low, high, id)

Removes an interval from the tree

tree.remove(10, 15, '123');

search(low, high)

Searches overlapping intervals in an inclusive range

const results = tree.search(10, 15);

Where results is an array of matching intervals, where each item is an array of 3 items:

[low, high, id]
