Method Detail

subscribeActual

protected void subscribeActual(MaybeObserver<? super T> observer)

Description copied from class: Maybe

Implement this method in subclasses to handle the incoming MaybeObservers.

There is no need to call any of the plugin hooks on the current Maybe instance or the MaybeObserver; all hooks and basic safeguards have been applied by Maybe.subscribe(MaybeObserver) before this method gets called.

Specified by:

subscribeActual in class Maybe<T>

Parameters:

observer - the MaybeObserver to handle, not null

get

public T get()
      throws java.lang.Exception

Description copied from interface: Supplier

Produces a value or throws an exception.

Specified by:

get in interface Supplier<T>

Returns:

the value produced

Throws:

java.lang.Exception
