Package rx.subjects

Class TestSubject<T>

java.lang.Object

rx.Observable<T>

rx.subjects.Subject<T,T>

rx.subjects.TestSubject<T>

Type Parameters:

T - the type of item observed by and emitted by the subject

All Implemented Interfaces:

Observer<T>

public final class TestSubject<T>
extends Subject<T,T>

A variety of Subject that is useful for testing purposes. It operates on a TestScheduler and allows you to precisely time emissions and notifications to the Subject's subscribers using relative virtual time controlled by the TestScheduler.

Method Details

create

public static <T> TestSubject<T> create(TestScheduler scheduler)

Creates and returns a new TestSubject.

Type Parameters:

T - the value type

Parameters:

scheduler - a TestScheduler on which to operate this Subject

Returns:

the new TestSubject

onCompleted

public void onCompleted()

Schedule a call to onCompleted on TestScheduler.

internalOnCompleted

void internalOnCompleted()

onCompleted

public void onCompleted(long delayTime)

Schedule a call to onCompleted relative to "now()" +n milliseconds in the future.

Parameters:

delayTime - the number of milliseconds in the future relative to "now()" at which to call onCompleted

onError

public void onError(Throwable e)

Schedule a call to onError on TestScheduler.

Parameters:

e - the exception encountered by the Observable

internalOnError

void internalOnError(Throwable e)

onError

public void onError(Throwable e,
 long delayTime)

Schedule a call to onError relative to "now()" +n milliseconds in the future.

Parameters:

e - the Throwable to pass to the onError method

delayTime - the number of milliseconds in the future relative to "now()" at which to call onError

onNext

public void onNext(T v)

Schedule a call to onNext on TestScheduler.

Parameters:

v - the item emitted by the Observable

internalOnNext

void internalOnNext(T v)

onNext

public void onNext(T v,
 long delayTime)

Schedule a call to onNext relative to "now()" +n milliseconds in the future.

Parameters:

v - the item to emit

delayTime - the number of milliseconds in the future relative to "now()" at which to call onNext

hasObservers

public boolean hasObservers()

Description copied from class: Subject

Indicates whether the Subject has Observers subscribed to it.

Specified by:

hasObservers in class Subject<T,T>

Returns:

true if there is at least one Observer subscribed to this Subject, false otherwise
