dependent disposable objects have been disposed.
Usage
The follow example shows the basic usage of an Rx.RefCountDisposable
.
var disposable = Rx.Disposable.create(() => console.log('disposed'));
var refCountDisposable = new Rx.RefCountDisposable(disposable);
// Try disposing before the underlying is disposed
refCountDisposable.dispose();
console.log(refCountDisposable.isDisposed);
// => false
// Dispose the underlying disposable
disposable.dispose();
// => disposed
// Now dispose the primary
refCountDisposable.dispose();
console.log(refCountDisposable.isDisposed);
// => true

RefCountDisposable Instance Methods
Rx.RefCountDisposable.prototype.dispose()
Disposes the underlying disposable only when all dependent disposables have been disposed.
例
var disposable = Rx.Disposable.create(() => console.log('disposed'));
var refCountDisposable = new Rx.RefCountDisposable(disposable);
// Try disposing before the underlying is disposed
refCountDisposable.dispose();
console.log(refCountDisposable.isDisposed);
// => false
// Dispose the underlying disposable
disposable.dispose();
// => disposed
// Now dispose the primary
refCountDisposable.dispose();
console.log(refCountDisposable.isDisposed);
// => true

Rx.RefCountDisposable.prototype.getDisposable()
Returns a dependent disposable that when disposed decreases the refcount on the underlying disposable.
返回值
(Disposable): A dependent disposable contributing to the reference count that manages the underlying disposable's lifetime.
例
var disposable = Rx.Disposable.create(() => console.log('disposed'));
var refCountDisposable = new Rx.RefCountDisposable(disposable);
var d = refCountDisposable.getDisposable();
console.log(d === disposable);
// => false
// Clean up disposables
disposable.dispose();
d.dispose();
// Now try to dispose the main
refCountDisposable.dispose();
console.log(refCountDisposable.isDisposed);
// => true
