qpid::messaging::Session::Session | ( | const Session & | ) |
qpid::messaging::Session::~Session | ( | ) |
void qpid::messaging::Session::acknowledge | ( | bool | sync = false |
) |
Acknowledges all outstanding messages that have been received by the application on this session.
sync | if true, blocks until the acknowledgement has been processed by the server |
void qpid::messaging::Session::checkError | ( | ) |
void qpid::messaging::Session::close | ( | ) |
Closes a session and all associated senders and receivers.
An opened session should be closed before the last handle to it goes out of scope. All a connections sessions can be closed by a call to Connection::close().
void qpid::messaging::Session::commit | ( | ) |
Receiver qpid::messaging::Session::createReceiver | ( | const std::string & | address | ) |
Create a new receiver through which messages can be received from the specified address.
Sender qpid::messaging::Session::createSender | ( | const std::string & | address | ) |
Create a new sender through which messages can be sent to the specified address.
Connection qpid::messaging::Session::getConnection | ( | ) | const |
Returns a handle to the connection this session is associated with.
uint32_t qpid::messaging::Session::getReceivable | ( | ) |
Returns the total number of messages received and waiting to be fetched by all Receivers belonging to this session.
This is the total number of available messages across all receivers on this session.
Receiver qpid::messaging::Session::getReceiver | ( | const std::string & | name | ) | const |
Returns the receiver with the specified name.
KeyError | if there is none for that name. |
Sender qpid::messaging::Session::getSender | ( | const std::string & | name | ) | const |
Returns the sender with the specified name.
KeyError | if there is none for that name. |
uint32_t qpid::messaging::Session::getUnsettledAcks | ( | ) |
Returns a count of the number of messages received this session that have been acknowledged, but for which that acknowledgement has not yet been confirmed as processed by the server.

Receiver qpid::messaging::Session::nextReceiver | ( | Duration | timeout = Duration::FOREVER |
) |
Returns the receiver for the next available message.
If there are no available messages at present the call will block for up to the specified timeout waiting for one to arrive.
Receiver::NoMessageAvailable | if no message became available in time. |
bool qpid::messaging::Session::nextReceiver | ( | Receiver & | , | |
Duration | timeout = Duration::FOREVER | |||
) |
Retrieves the receiver for the next available message.
If there are no available messages at present the call will block for up to the specified timeout waiting for one to arrive. Returns true if a message was available at the point of return, in which case the passed in receiver reference will be set to the receiver for that message or false if no message was available.
QPID_MESSAGING_EXTERN qpid::messaging::Handle< SessionImpl >::operator bool | ( | ) | const [inline, inherited] |

QPID_MESSAGING_EXTERN bool qpid::messaging::Handle< SessionImpl >::operator! | ( | ) | const [inline, inherited] |

void qpid::messaging::Session::reject | ( | Message & | ) |
Rejects the specified message.
This will prevent the message being redelivered. This must be called before the message is acknowledged.
void qpid::messaging::Session::release | ( | Message & | ) |
Releases the specified message.
This will allow the broker to redeliver the message. This must be called before the message is acknowledged.

void qpid::messaging::Session::sync | ( | bool | block = true |
) |
Request synchronisation with the server.
block | if true, this call will block until the server confirms completion of all pending operations; if false the call will request notifcation from the server but will return before receiving it. |
