AbstractReactorMessageHandler

public AbstractReactorMessageHandler(Processor processor)

Construct a new BroadcasterMessageHandler given the reactor based Processor to delegate processing to.

Parameters:

processor - The stream based reactor processor

Method Detail

setStopTimeout

public void setStopTimeout(int stopTimeoutInMillis)

Time in milliseconds to wait when shutting down the processor, waiting on a latch inside the onComplete method of the subscriber. Default is 5000 milliseconds

Parameters:

stopTimeoutInMillis - time to wait when shutting down the processor.

getStopTimeout

public int getStopTimeout()

Return the time to wait when shutting down the processor in millseconds

setRingBufferSize

public void setRingBufferSize(int ringBufferSize)

The size of the RingBuffer, must be a power of 2. Default is 8192.

Parameters:

ringBufferSize - size of the RingBuffer.

getRingBufferSize

public int getRingBufferSize()

Return the size of the RingBuffer

getEnvironment

public reactor.Environment getEnvironment()

Return the environment to use for stream processing operations.

getInputType

public java.lang.Class<?> getInputType()

Returns the input type of the stream that is to be processed

invokeProcessor

protected void invokeProcessor(org.springframework.messaging.Message<?> message,
                   reactor.core.processor.RingBufferProcessor<java.lang.Object> reactiveProcessorToUse)
