nonoverlapping-interval-tree

Non-overlapping interval tree for NodeJS.

Features:

• Two intervals can not overlap. If there is a conflict only the last interval added will be stored.
• If two adjacent intervals have the same data stored, they will be merged automatically into one.

Install

npm install nonoverlapping-interval-tree

Usage

const { NonOverlappingIntervalTree } = require('nonoverlapping-interval-tree')

const tree = new NonOverlappingIntervalTree()

tree.add(1, 5) // [1, 5]

tree.remove(2, 3) // [1, 1], [4, 5]

API

const tree = new NonOverlappingIntervalTree()

Initialize the tree

tree.add(from, to, [data])
