PowerReference

PowerReference makes using WeakReferences cleaner and easier.

Building

PowerReference is hosted on Jitpack. To build it, add jitpack to your sources.

maven { url 'https://jitpack.io' }

Include PowerReference.

dependencies {
  implementation 'com.github.garretyoder:PowerReference:1.0'
}

Usage

Make a reference.

val ref = myObject.asReference()

Get object from your reference.

ref()

The object will be nullable (?) because your WeakReference may have been garbage collected since it's creation. To use it you will have to null check it.

ref()?.let {
  //TODO: do something with the object
}

PowerReference provides a simple extension function to make the above pattern easier, safe. The safe method will work on any object, not just PowerReferences.

ref().safe {
  //TODO: do something with the object
}
