binary-map

binary-map

In-memory key/value store based on a binary search, that supports buffers as keys.

example

var BinaryMap = require('binary-map')

var bm = BinaryMap()

bm.set(key, value)
value = bm.get(key)

API

bm = BinaryMap(comparator?)

create a new binary-map instance with the given comparator. By default typewiselite is used, which should be sufficent for most purposes.

BinaryMap#set(key, value)

set a key to a value

BinaryMap#add({key, value})

Like set, except add a pair of values. The object passed in will be used in the external datastructure, so do not mutate it after calling this.

BinaryMap#get(key)

return the value for key, or undefined

BinaryMap#has(key)

return true if key is stored.

i = BinaryMap#getIndex(key)

return the index key is stored at in the internal array. If return value is negative, key is not in the array. Since binary-map wraps binary-search ~i will be the value of the closest key (the item currently where this key would be if it was in the map)

BinaryMap#store

The internal array. Realize that if you mutate this you might break stuff if you do not preserve the order of the keys.

BinaryMap#toJSON()

Return a copy of the internal array. This does not clone the keys or values, so if you mutate something it could break.
