thirsty

thirsty is a simple Object Pool implementation for Javascript.

Object pools help you tame the garbage collector by making it easy to preallocate and reuse objects. This is especially useful on mobile platforms.

Use

makePool(obj, num)

Creates an Object Pool containing an array of num objects that are equivalent to obj

Example

This example creates a pool of 100 objects that look like {name: 'Mack', age: 52}.

const thirsty = require('thirsty');

const template = {name: 'Mack', age: 52};

const pool = thirsty.makePool(template, 100);

get(pool)

Returns the next available object in pool Throws exception if pool is full

const thirsty = require('thirsty');

const template = {name: 'Mack', age: 52};

const pool = thirsty.makePool(template, 100);

const obj = thirsty.get(pool); // Returns first object in pool

scrub(pool, obj)

Resets obj in pool and marks it as free Throws error if obj is not in pool

const thirsty = require('thirsty');

const template = {name: 'Mack', age: 52};

const pool = thirsty.makePool(obj, 2);

const obj = thirsty.get(pool);

obj.name = 'Philip';
obj.age  = 28;

thirsty.scrub(pool, obj)
// pool.array[0] is once again {name: 'Mack', age: 52}
