com.mysql.cj.protocol.SerializingBufferWriter

所有已实现的接口:

CompletionHandler<Long,Void>

public class SerializingBufferWriter
extends Object
implements CompletionHandler<Long,Void>

A layer over AsynchronousSocketChannel that serializes all incoming write requests. This means we queue any incoming buffer and don't begin writing it until the previous buffer has been written fully. All buffers are transmitted atomically with respect to the caller/callback.

SerializingBufferWriter

public SerializingBufferWriter(AsynchronousSocketChannel channel)

方法详细资料

queueBuffer

public void queueBuffer(ByteBuffer buf,
                        CompletionHandler<Long,Void> callback)

Queue a buffer to be written to the channel. This method uses a mutex on the buffer list to synchronize for the following cases:

• The buffer list becomes empty after we check and miss writing to the channel.
• LinkedList is not thread-safe.

参数:

buf - ByteBuffer

callback - CompletionHandler

completed

public void completed(Long bytesWritten,
                      Void v)

Completion handler for channel writes.

指定者:

completed 在接口中 CompletionHandler<Long,Void>

参数:

bytesWritten - number of processed bytes

v - Void

failed

public void failed(Throwable t,
                   Void v)

指定者:

failed 在接口中 CompletionHandler<Long,Void>

setChannel

public void setChannel(AsynchronousSocketChannel channel)

Allow overwriting the channel once the writer has been established. Required for SSL/TLS connections when the encryption doesn't start until we send the capability flag to X Plugin.

参数:

channel - AsynchronousSocketChannel
