Description copied from interface: WriteHandler

A callback to indicate that the Frame should be written to the destination ByteBuffer. It could be that a Frame is too big to fit into the ByteBuffer in 1 go; in that case this call will be made for the same Frame multiple times until write returns true. It is up to the Frame to track where it needs to continue.

Specified by:

onWrite in interface WriteHandler<ClientMessage>

Parameters:

message - the Frame to write

dst - the destination ByteBuffer

Returns:

true if the Frame is completely written

Throws:

Exception - if something fails while writing to ByteBuffer. When an exception is thrown, the TcpIpConnection is closed. There is no point continuing with a potentially corrupted stream.
