Constructor Detail

TimedBuffer

public TimedBuffer(org.apache.activemq.artemis.utils.critical.CriticalAnalyzer analyzer,
                   int size,
                   int timeout,
                   boolean logRates)

Method Detail

start

public void start()

stop

public void stop()

setObserver

public void setObserver(TimedBufferObserver observer)

checkSize

public boolean checkSize(int sizeChecked)

Verify if the size fits the buffer

Parameters:

sizeChecked -

addBytes

public void addBytes(org.apache.activemq.artemis.api.core.ActiveMQBuffer bytes,
                     boolean sync,
                     IOCallback callback)

addBytes

public void addBytes(EncodingSupport bytes,
                     boolean sync,
                     IOCallback callback)

flush

public void flush()

flushBatch

public boolean flushBatch()

Attempts to flush if !delayFlush and buffer is filled by any data.

Returns:

true when are flushed any bytes, false otherwise

sleep

protected void sleep(long sleepNanos)

Sub classes (tests basically) can use this to override how the sleep is being done

Parameters:

sleepNanos -

stopSpin

protected void stopSpin()

Sub classes (tests basically) can use this to override disabling spinning

startSpin

protected void startSpin()

Sub classes (tests basically) can use this to override disabling spinning
