Enum | Description |
---|---|
LRAStatus |
A representation of the status of a Long Running Action according to a LRA state model:
The initial state
LRAStatus.Active is entered when an LRA is created. |
ParticipantStatus |
A representation of the status of a participant according to a participant state model:
The initial state
ParticipantStatus.Active is entered when a participant is first associated with a Long Running Action. |
Annotation Type | Description |
---|---|
AfterLRA |
If a JAX-RS resource method is annotated with
LRA and is invoked in the context of an LRA then the resource
can ask to be notified when the LRA finishes by marking one of the other methods in the class with the
@AfterLRA annotation. |
Compensate |
If a resource method executes in the context of an LRA and if the containing class has a method annotated with
@Compensate then this method will be invoked if the LRA is cancelled. |
Complete |
If a resource method executes in the context of an LRA and if the containing class has a method annotated with
@Complete (as well as method annotated with @Compensate ) then this Complete method
will be invoked if the LRA is closed. |
Forget |
If a participant is unable to complete or compensate immediately (i.e., it has indicated that the request has been
accepted and is in progress) or because of a failure (i.e., will never be able to finish) then it must remember the
fact (by reporting it when asked for its
Status ) until explicitly told that it can clean up using this
@Forget annotation. |
Status |
The LRA specification supports distributed communications amongst software components and due to the unreliable
nature of networks, messages/requests can be lost, delayed, duplicated, etc., so the implementation component
responsible for invoking
Compensate and Complete annotated methods may lose track of the status of a
participant. |
