Weakref

Weak Reference class that allows a referenced object to be garbage-collected.

A WeakRef may be used exactly like the object it references.

Installation

Add this line to your application's Gemfile:

gem'weakref'

And then execute:

$ bundle

Or install it yourself as:

$ gem install weakref

Usage

foo=Object.new# create a new object instancepfoo.to_s# original's classfoo=WeakRef.new(foo)# reassign foo with WeakRef instancepfoo.to_s# should be same classGC.start# start the garbage collectorpfoo.to_s# should raise exception (recycled)

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
