Class QosIdentifiersImpl

java.lang.Object
  cgl.narada.service.qos.impl.QosIdentifiersImpl

All Implemented Interfaces:

QosIdentifiers

public class QosIdentifiersImpl
extends Object
implements QosIdentifiers

The QosIdentofiers can be used to achieve various delivery schemes such as all-or-none, at-most-once, at-least-once, exactly-once, causal-ordered, publisher-ordered, time-constrained

Method Summary

boolean	hasSatisfiedCausalConstraints() Has satisfied any causal constraints that might be contained in the event
boolean	hasSatisfiedTimingConstraints() This would be based on the global NaradaBrokering clock

boolean	isDuplicate() Indicates if this event is a duplicate event
boolean	isOrdered() Indicates whether the event has satisfied ordering constraints and is ready for release.
boolean	isTimeOrdered() Checks to see if the event is ordered in time based on the NB clock

Method Detail

isArchived

public boolean isArchived()

Indicates if the event in question has been archived. This can be used to implement the all-or-none primitive.

Specified by:

isArchived in interface QosIdentifiers

setArchived

protected void setArchived()

hasSatisfiedCausalConstraints

public boolean hasSatisfiedCausalConstraints()

Has satisfied any causal constraints that might be contained in the event

Specified by:

hasSatisfiedCausalConstraints in interface QosIdentifiers

setSatisfiedCausalConstraints

protected void setSatisfiedCausalConstraints()

isDuplicate

public boolean isDuplicate()

Indicates if this event is a duplicate event

Specified by:

isDuplicate in interface QosIdentifiers

setDuplicate

protected void setDuplicate()

isOrdered

public boolean isOrdered()

Indicates whether the event has satisfied ordering constraints and is ready for release. Specifically publisher ordering

Specified by:

isOrdered in interface QosIdentifiers

setOrdered

protected void setOrdered()

hasSatisfiedTimingConstraints

public boolean hasSatisfiedTimingConstraints()

This would be based on the global NaradaBrokering clock

Specified by:
