object-pool-2

A constructor specific object pool implementation for asynchronous recycling of object allocations.

Installation

npm install object-pool-2 --save

Usage

var objectPool = require('object-pool-2')(Constructor);

Creates a new object pool. Accepts an Constructor which will be used internally in order to instantiate new Constructor instances (via new Constructor).

objectPool.allocate(callback)

Asynchronous. Allocates a new Constructor instance. This either results into a new instance being created or a previously deallocated instance being reused.

objectPool.deallocate()

Deallocates a allocated Constructor instance. This enables the object to be reused if needed.

objectPool.max = 10

Maximum number of internally managed Constructor instances. Defaults to 10. Will throw an error if max < inUse.

objectPool.available

Read-only. Number of available, but not necessarily allocated, Constructor instances.

objectPool.inUse

Read-only. Number of internally managed allocated (therefore not de-allocated) Constructor instances.
