Constructor Detail

UdpAssociationHandle

public UdpAssociationHandle(Address localAddress,
                            Address remoteAddress,
                            org.jboss.netty.channel.Channel channel,
                            NettyTransport transport)

Method Detail

localAddress

public Address localAddress()

Description copied from interface: AssociationHandle

Address of the local endpoint.

Specified by:

localAddress in interface AssociationHandle

Returns:

Address of the local endpoint.

remoteAddress

public Address remoteAddress()

Description copied from interface: AssociationHandle

Address of the remote endpoint.

Specified by:

remoteAddress in interface AssociationHandle

Returns:

Address of the remote endpoint.

readHandlerPromise

public scala.concurrent.Promise<AssociationHandle.HandleEventListener> readHandlerPromise()

Description copied from interface: AssociationHandle

The Promise returned by this call must be completed with an AssociationHandle.HandleEventListener to register a listener responsible for handling incoming payload. Until the listener is not registered the transport SHOULD buffer incoming messages.

Specified by:

readHandlerPromise in interface AssociationHandle

Returns:

Promise that must be completed with the listener responsible for handling incoming data.

write

public boolean write(ByteString payload)

Description copied from interface: AssociationHandle

Asynchronously sends the specified payload to the remote endpoint. This method MUST be thread-safe as it might be called from different threads. This method MUST NOT block.

Writes guarantee ordering of messages, but not their reception. The call to write returns with a Boolean indicating if the channel was ready for writes or not. A return value of false indicates that the channel is not yet ready for delivery (e.g.: the write buffer is full) and the sender needs to wait until the channel becomes ready again. Returning false also means that the current write was dropped (this MUST be guaranteed to ensure duplication-free delivery).

Specified by:

write in interface AssociationHandle

Parameters:

payload - The payload to be delivered to the remote endpoint.

Returns:

Boolean indicating the availability of the association for subsequent writes.

disassociate

public void disassociate()

Description copied from interface: AssociationHandle

Closes the underlying transport link, if needed. Some transports might not need an explicit teardown (UDP) and some transports may not support it (hardware connections). Remote endpoint of the channel or connection MAY be notified, but this is not guaranteed. The Transport that provides the handle MUST guarantee that disassociate() could be called arbitrarily many times.

Specified by:

disassociate in interface AssociationHandle
