Member Function Documentation

void isc::config::ClientConnectionImpl::doReceive ( ClientConnection::Handler handler )

Starts asynchronous receive from the server.

This method may be called multiple times internally if the response is large. The JSONFeed instance is used to detect the boundaries of the command within the stream. Once the entire command has been received the user callback is invoked and the instance of the JSONFeed is returned.

Parameters

handler User supplied callback.

Definition at line 204 of file client_connection.cc.

void isc::config::ClientConnectionImpl::doSend	(	const void *	buffer,
		const size_t	length,
		ClientConnection::Handler	handler
	)

Starts asynchronous send.

This method may be called multiple times internally when the command is large and can't be sent all at once.

Parameters

buffer	Pointer to the buffer holding input data.
length	Length of the data in the input buffer.
handler	User supplied callback invoked after the chunk of data has been sent.

Definition at line 167 of file client_connection.cc.

void isc::config::ClientConnectionImpl::scheduleTimer ( ClientConnection::Handler handler )

This method schedules timer or reschedules existing timer.

Parameters

handler Pointer to the user supplied callback function which should be invoked when transaction completes or when an error has occurred during the transaction.

		const ClientConnection::ControlCommand &	command,
		ClientConnection::Handler	handler,
		const ClientConnection::Timeout &	timeout
	)

Starts asynchronous transaction with a remote endpoint.

See ClientConnection::start documentation for the details.

Parameters

socket_path	Path to the socket description that the server is bound to.
command	Control command to be sent to the server.
handler	Pointer to the user supplied callback function which should be invoked when transaction completes or when an error has occurred during the transaction.
timeout	Connection timeout in milliseconds.
