Constructor Detail

InMemoryResumableFramesStore

public InMemoryResumableFramesStore(String tag,
                                    int cacheSizeBytes)

Method Detail

saveFrames

public Mono<Void> saveFrames(Flux<ByteBuf> frames)

Description copied from interface: ResumableFramesStore

Save resumable frames for potential resumption

Specified by:

saveFrames in interface ResumableFramesStore

Parameters:

frames - Flux of resumable frames

Returns:

Mono which completes once all resume frames are written

releaseFrames

public void releaseFrames(long remoteImpliedPos)

Description copied from interface: ResumableFramesStore

Release frames from tail of the store up to remote implied position

Specified by:

releaseFrames in interface ResumableFramesStore

resumeStream

public Flux<ByteBuf> resumeStream()

Specified by:

resumeStream in interface ResumableFramesStore

Returns:

Flux of frames from store tail to head. It should terminate with error if frames are not continuous

framePosition

public long framePosition()

Specified by:

framePosition in interface ResumableFramesStore

Returns:

Local frame position as defined by RSocket protocol

frameImpliedPosition

public long frameImpliedPosition()

Specified by:

frameImpliedPosition in interface ResumableFramesStore

Returns:

Implied frame position as defined by RSocket protocol

resumableFrameReceived

public void resumableFrameReceived(ByteBuf frame)

Description copied from interface: ResumableFramesStore

Received resumable frame as defined by RSocket protocol. Implementation must increment frame implied position

Specified by:

resumableFrameReceived in interface ResumableFramesStore

onClose

public Mono<Void> onClose()

Description copied from interface: Closeable

Returns a Mono that terminates when the instance is terminated by any reason. Note, in case of error termination, the cause of error will be propagated as an error signal through Subscriber.onError(Throwable). Otherwise, Subscriber.onComplete() will be called.

Specified by:

onClose in interface Closeable

Returns:

a Mono to track completion with success or error of the underlying resource. When the underlying resource is an `RSocket`, the Mono exposes stream 0 (i.e. connection level) errors.

dispose

public void dispose()

Specified by:

dispose in interface Disposable

isDisposed

public boolean isDisposed()

Specified by:

isDisposed in interface Disposable
