Member Function Documentation

void qpid::messaging::Receiver::close ( )

Cancels this receiver.

bool qpid::messaging::Receiver::fetch ( Message message,
Duration  timeout = Duration::FOREVER 
)

Retrieves a message for this receivers subscription or waits for up to the specified timeout for one to become available.

Unlike get() this method will check with the server that there is no message for the subscription this receiver is serving before returning false.

Returns:
false if there is no message to give after waiting for the specified timeout, or if the Receiver is closed, in which case isClose() will be true.
Message qpid::messaging::Receiver::fetch ( Duration  timeout = Duration::FOREVER)

Retrieves a message for this receivers subscription or waits for up to the specified timeout for one to become available.

Unlike get() this method will check with the server that there is no message for the subscription this receiver is serving before throwing an exception.

Exceptions:
NoMessageAvailableif there is no message to give after waiting for the specified timeout, or if the Receiver is closed, in which case isClose() will be true.
bool qpid::messaging::Receiver::get ( Message message,
Duration  timeout = Duration::FOREVER 
)

Retrieves a message from this receivers local queue, or waits for upto the specified timeout for a message to become available.

Message qpid::messaging::Receiver::get ( Duration  timeout = Duration::FOREVER)

Retrieves a message from this receivers local queue, or waits for up to the specified timeout for a message to become available.

Exceptions:
NoMessageAvailableif there is no message to give after waiting for the specified timeout, or if the Receiver is closed, in which case isClose() will be true.
uint32_t qpid::messaging::Receiver::getAvailable ( )
Returns:
the number of messages received and waiting to be fetched.
uint32_t qpid::messaging::Receiver::getCapacity ( )
Returns:
the capacity of the receiver. The capacity determines how many incoming messages can be held in the receiver before being requested by a client via fetch() (or pushed to a listener).
const std::string& qpid::messaging::Receiver::getName ( ) const

Returns the name of this receiver.

Session qpid::messaging::Receiver::getSession ( ) const

Returns a handle to the session associated with this receiver.

uint32_t qpid::messaging::Receiver::getUnsettled ( )
Returns:
a count of the number of messages received on this receiver that have been acknowledged, but for which that acknowledgement has not yet been confirmed as processed by the server.
bool qpid::messaging::Receiver::isClosed ( ) const

Return true if the receiver was closed by a call to close()

QPID_MESSAGING_INLINE_EXTERN bool qpid::messaging::Handle< ReceiverImpl >::isNull ( ) const [inline, inherited]
Returns:
true if handle is null. It is an error to call any function on a null handle.

Definition at line 46 of file Handle.h.

QPID_MESSAGING_INLINE_EXTERN bool qpid::messaging::Handle< ReceiverImpl >::isValid ( ) const [inline, inherited]
Returns:
true if handle is valid, i.e. not null.

Definition at line 43 of file Handle.h.

QPID_MESSAGING_INLINE_EXTERN qpid::messaging::Handle< ReceiverImpl >::operator bool ( ) const [inline, inherited]

Conversion to bool supports idiom if (handle) { handle->...

}

Definition at line 49 of file Handle.h.

QPID_MESSAGING_INLINE_EXTERN bool qpid::messaging::Handle< ReceiverImpl >::operator! ( ) const [inline, inherited]

Operator ! supports idiom if (!handle) { do_if_handle_is_null(); }.

Definition at line 52 of file Handle.h.

Receiver& qpid::messaging::Receiver::operator= ( const Receiver )
void qpid::messaging::Receiver::setCapacity ( uint32_t  )

Sets the capacity for the receiver.

The capacity determines how many incoming messages can be held in the receiver before being requested by a client via fetch() (or pushed to a listener).

void qpid::messaging::Handle< ReceiverImpl >::swap ( Handle< ReceiverImpl > &  h) [inline, inherited]
