Detailed Description

Specification of desired quality of service settings for sending and receiving events.

Specification given here are required "at least". This means concrete port instances can implement "better" QoS specs without any notification to the clients. Better is decided by the integer value of the specification enums. Higher values mean better services.

Member Enumeration Documentation

enum rsb::QualityOfServiceSpec::Ordering

Specifies the ordering of events for listeners on a informer.

Author: jwienke

Enumerator:

UNORDERED

The events are delivered in arbitrary order.

ORDERED

Every listener receives the events of one informer in the order the informer sent the events.

No guarantees are given for events of multiple informers.

Definition at line 56 of file QualityOfServiceSpec.h.

enum rsb::QualityOfServiceSpec::Reliability

Specifies the reliability of messages.

Author: jwienke

Enumerator:

UNRELIABLE

Events may be dropped and not be visible to a listener.

RELIABLE

Messages are guaranteed to be delivered.

Otherwise an error is raised.

Definition at line 74 of file QualityOfServiceSpec.h.
