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. |
