Package Exports

refpool

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (refpool) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

refpool

Pool of references that gc the least recently unref'ed ones when it reaches a max size

npm install refpool

Usage

const Pool = require('refpool')

const p = new Pool({
  maxSize: 42,
  close (data) {
    console.log('should close', data)
  }
})

const someResource = ...

p.set(key, val) // add a key to the pool
p.get(key) // get a val (bumps it) get(key, false) does not bump
p.add(data) // sugar for p.set(data, data)
const e = p.entry(key) // get the cache entry object out.
                       // you can call e.increment, decrement and bump on this direcly

p.increment(key) // add it and increment the reference count
p.decrement(key) // decrement the ref count
p.bump(key) // indicate that you used a thing in the pool

When more than maxSize items are inserted the least recently used resource with no references will be passed to close.
