◆ handleDisconnect()

void llvm::orc::SimpleRemoteEPCServer::handleDisconnect ( Error Err )

overridevirtual

Handle a disconnection from the underlying transport.

No further messages should be sent to handleMessage after this is called. Err may contain an Error value indicating unexpected disconnection. This allows clients to log such errors, but no attempt should be made at recovery (which should be handled inside the transport class, if it is supported at all).

Implements llvm::orc::SimpleRemoteEPCTransportClient.

		uint64_t	SeqNo,
		ExecutorAddr	TagAddr,
		SimpleRemoteEPCArgBytesVector	ArgBytes
	)

overridevirtual

Call to handle an incoming message.

Returns 'Disconnect' if the message is a 'detach' message from the remote otherwise returns 'Continue'. If the server has moved to an error state, returns an error, which should be reported and treated as a 'Disconnect'.

Implements llvm::orc::SimpleRemoteEPCTransportClient.
