resource - the resource to add

onSubscribe

public final void onSubscribe(Disposable s)

Description copied from interface: SingleObserver

Provides the SingleObserver with the means of cancelling (disposing) the connection (channel) with the Single in both synchronous (from within onSubscribe(Disposable) itself) and asynchronous manner.

Specified by:

onSubscribe in interface SingleObserver<T>

Parameters:

s - the Disposable instance whose Disposable.dispose() can be called anytime to cancel the connection

onStart

protected void onStart()

Called once the upstream sets a Subscription on this ResourceObserver.

You can perform initialization at this moment. The default implementation does nothing.

dispose

public final void dispose()

Cancels the main disposable (if any) and disposes the resources associated with this ResourceObserver (if any).

This method can be called before the upstream calls onSubscribe at which case the main Disposable will be immediately disposed.

isDisposed

public final boolean isDisposed()

Returns true if this ResourceObserver has been disposed/cancelled.

Specified by:

isDisposed in interface Disposable

Returns:

true if this ResourceObserver has been disposed/cancelled
