Detailed Description

A named channel for sending or receiving messages.

It is the base class for sender and receiver.

Member Function Documentation

uninitialized()

bool uninitialized ( ) const

virtual

True if the local end is uninitialized.

Implements endpoint.

active()

bool active ( ) const

virtual

True if the local end is active.

Implements endpoint.

closed()

bool closed ( ) const

virtual

True if the local and remote ends are closed.

Implements endpoint.

error()

class error_condition error ( ) const

virtual

Get the error condition of the remote endpoint.

Implements endpoint.

close() [1/2]

void close ( )

virtual

Close the endpoint.

Implements endpoint.

Examples

broker.cpp, direct_recv.cpp, helloworld.cpp, service_bus.cpp, and simple_recv.cpp.

close() [2/2]

void close ( const error_condition &  )

virtual

Close the endpoint with an error condition.

Implements endpoint.

detach()

void detach

(

)

Suspend the link without closing it.

A suspended link may be reopened with the same or different link options if supported by the peer. A suspended durable subscription becomes inactive without cancelling it.

draining()

bool draining

(

)

Unsettled API - True for a receiver if a drain cycle has been started and the corresponding on_receiver_drain_finish event is still pending.

True for a sender if the receiver has requested a drain of credit and the sender has unused credit.

receiver::drain.
