Method Detail

onComplete
public void onComplete()
Description copied from interface:CompletableEmitter
Signal the completion.- Specified by:
onComplete
in interfaceCompletableEmitter
-
onError
public void onError(java.lang.Throwable t)
Description copied from interface:CompletableEmitter
Signal an exception.- Specified by:
onError
in interfaceCompletableEmitter
- Parameters:
t
- the exception, not null
-
tryOnError
public boolean tryOnError(java.lang.Throwable t)
Description copied from interface:CompletableEmitter
Attempts to emit the specifiedThrowable
error if the downstream hasn't cancelled the sequence or is otherwise terminated, returning false if the emission is not allowed to happen due to lifecycle restrictions.Unlike
CompletableEmitter.onError(Throwable)
, theRxjavaPlugins.onError
is not called if the error could not be delivered.History: 2.1.1 - experimental
- Specified by:
tryOnError
in interfaceCompletableEmitter
- Parameters:
t
- the throwable error to signal if possible- Returns:
- true if successful, false if the downstream is not able to accept further events
-
setDisposable
public void setDisposable(Disposable d)
Description copied from interface:CompletableEmitter
Sets a Disposable on this emitter; any previousDisposable
orCancellable
will be disposed/cancelled.- Specified by:
setDisposable
in interfaceCompletableEmitter
- Parameters:
d
- the disposable, null is allowed
-
setCancellable
public void setCancellable(Cancellable c)
Description copied from interface:CompletableEmitter
Sets a Cancellable on this emitter; any previousDisposable
orCancellable
will be disposed/cancelled.- Specified by:
setCancellable
in interfaceCompletableEmitter
- Parameters:
c
- the cancellable resource, null is allowed
-
dispose
public void dispose()
Description copied from interface:Disposable
Dispose the resource, the operation should be idempotent.- Specified by:
dispose
in interfaceDisposable
-
isDisposed
public boolean isDisposed()
Description copied from interface:CompletableEmitter
Returns true if the downstream disposed the sequence or the emitter was terminated viaCompletableEmitter.onError(Throwable)
,CompletableEmitter.onComplete()
or a successfulCompletableEmitter.tryOnError(Throwable)
.This method is thread-safe.
- Specified by:
isDisposed
in interfaceCompletableEmitter
- Specified by:
isDisposed
in interfaceDisposable
- Returns:
- true if the downstream disposed the sequence or the emitter was terminated
-
