Method Detail

finallyDo

public static <T> Observable.OnSubscribeFunc<T> finallyDo(Observable<? extends T> sequence,
                                                          Action0 action)

Call a given action when a sequence completes (with or without an exception). The returned observable is exactly as threadsafe as the source observable.

Note that "finally" is a Java reserved word and cannot be an identifier, so we use "finallyDo".

Parameters:

sequence - An observable sequence of elements

action - An action to be taken when the sequence is complete or throws an exception

Returns:

An observable sequence with the same elements as the input. After the last element is consumed (and Observer.onCompleted() has been called), or after an exception is thrown (and Observer.onError(java.lang.Throwable) has been called), the given action will be called.
