Class AMQProtocolSession

java.lang.Object

org.apache.qpid.client.protocol.AMQProtocolSession

All Implemented Interfaces:

AMQProtocolWriter, AMQVersionAwareProtocolSession, ProtocolVersionAware

public class AMQProtocolSession
extends Object
implements AMQVersionAwareProtocolSession

Wrapper for protocol session that provides type-safe access to session attributes.

The underlying protocol session is still available but clients should not use it to obtain session attributes.

public void contentBodyReceived(int channelId,
                       ContentBody contentBody)
                         throws QpidException

getSession

protected AMQSession getSession(int channelId)

writeFrame

public void writeFrame(AMQDataBlock frame)

Description copied from interface: AMQProtocolWriter

Writes a frame to the wire, encoding it as necessary, for example, into a sequence of bytes.

Specified by:

writeFrame in interface AMQProtocolWriter

Parameters:

frame - The frame to be encoded and written.

closeSession

public void closeSession(AMQSession<?,?> session)

Starts the process of closing a session

Parameters:

session - the AMQSession being closed

channelClosed

public boolean channelClosed(int channelId,
                    int code,
                    String text)
                      throws QpidException

Called from the ChannelClose handler when a channel close frame is received. This method decides whether this is a response or an initiation. The latter case causes the AMQSession to be closed and an exception to be thrown if appropriate.

Parameters:

channelId - the id of the channel (session)

Returns:

true if the client must respond to the server, i.e. if the server initiated the channel close, false if the channel close is just the server responding to the client's earlier request to close the channel.

Throws:

QpidException
