Direct Known Subclasses:

GrizzlyWriter

public abstract class Writer
extends java.lang.Object
implements java.io.Closeable

Writer class that is used by tyrus runtime to pass outbound websocket data for a connection to a transport. Then, the transport actually writes the data eventually.

A transport creates implementation of this class and registers the writer object using WebSocketEngine.UpgradeInfo.createConnection(org.glassfish.tyrus.spi.Writer, org.glassfish.tyrus.spi.Connection.CloseListener) after a successful upgrade.

Method Detail

write

public abstract void write(java.nio.ByteBuffer buffer,
                           CompletionHandler<java.nio.ByteBuffer> completionHandler)

A backward compatible method called from write(ByteBuffer, CompletionHandler, WriterInfo) to handover the data for a connection to the transport. The transport writes bytes to underlying connection. Tyrus runtime must not use the buffer until the write is completed.

The method will be removed in the next major version.

Parameters:

buffer - bytes to write.

completionHandler - completion handler to know the write status.

write

public void write(java.nio.ByteBuffer buffer,
                  CompletionHandler<java.nio.ByteBuffer> completionHandler,
                  WriterInfo writerInfo)

Tyrus runtime calls this method to handover the data for a connection to the transport. The transport writes bytes to underlying connection. Tyrus runtime must not use the buffer until the write is completed.

Parameters:

buffer - bytes to write.

completionHandler - completion handler to know the write status.

writerInfo - additional information about the data to be written.
