Constructor Detail

NioEventLoop

public NioEventLoop(EventPolicy policy,
                    SelectorProvider provider,
                    int index)
             throws IOException

Construct Aerospike event loop wrapper from NIO Selector.

Throws:

IOException

Method Detail

execute

public void execute(com.aerospike.client.cluster.Cluster cluster,
                    com.aerospike.client.async.AsyncCommand command)

Execute async command. Execute immediately if in event loop. Otherwise, place command on event loop queue.

Specified by:

execute in interface EventLoop

execute

public void execute(Runnable command)

Schedule execution of runnable command on event loop. Command is placed on event loop queue and is never executed directly.

Specified by:

execute in interface EventLoop

executeBatchRetry

public void executeBatchRetry(Runnable other,
                              com.aerospike.client.async.AsyncCommand command,
                              long deadline)

Execute async batch retry.

Specified by:

executeBatchRetry in interface EventLoop

schedule

public void schedule(Runnable command,
                     long delay,
                     TimeUnit unit)

Schedule execution of runnable command with delay in milliseconds.

Specified by:

schedule in interface EventLoop

schedule

public void schedule(com.aerospike.client.async.ScheduleTask task,
                     long delay,
                     TimeUnit unit)

Schedule execution with a reusable ScheduleTask. Saves memory allocation for repeatedly scheduled task.

Specified by:

schedule in interface EventLoop

inEventLoop

public boolean inEventLoop()

Is current thread the event loop thread.

Specified by:

inEventLoop in interface EventLoop

createByteBuffer

public static ByteBuffer createByteBuffer(int size)

getByteBuffer

public ByteBuffer getByteBuffer()

putByteBuffer

public void putByteBuffer(ByteBuffer byteBuffer)

run

public void run()

Specified by:

run in interface Runnable

close

public void close()
