Constructor Detail

AbstractAnnotatedSaga

protected AbstractAnnotatedSaga()

Initialize the saga with a random identifier. The identifier used is provided by IdentifierFactory.generateIdentifier(), which defaults to a randomly generated UUID.

AbstractAnnotatedSaga

protected AbstractAnnotatedSaga(String identifier)

Initialize the saga with the given identifier.

Parameters:

identifier - the identifier to initialize the saga with.

Method Detail

getSagaIdentifier

public String getSagaIdentifier()

Description copied from interface: Saga

Returns the unique identifier of this saga.

Specified by:

getSagaIdentifier in interface Saga

Returns:

the unique identifier of this saga

getAssociationValues

public AssociationValues getAssociationValues()

Description copied from interface: Saga

Returns a view on the Association Values for this saga instance. The returned instance is mutable.

Specified by:

getAssociationValues in interface Saga

Returns:

a view on the Association Values for this saga instance

handle

public final void handle(EventMessage event)

Description copied from interface: Saga

Handle the given event. The actual result of processing depends on the implementation of the saga.

Implementations are highly discouraged from throwing exceptions.

Specified by:

handle in interface Saga

Parameters:

event - the event to handle

registerParameterResolverFactory

protected void registerParameterResolverFactory(ParameterResolverFactory parameterResolverFactory)

Sets the ParameterResolverFactory for this instance to use. This is typically set by the SagaManager that will manage the lifecycle of this instance.

Parameters:

parameterResolverFactory - The parameterResolverFactory for this instance to use

isActive

public boolean isActive()

Description copied from interface: Saga

Indicates whether or not this saga is active. A Saga is active when its life cycle has not been ended.

Specified by:

isActive in interface Saga

Returns:

true if this saga is active, false otherwise.

end

protected void end()

Marks the saga as ended. Ended saga's may be cleaned up by the repository when they are committed.

associateWith

protected void associateWith(AssociationValue property)

Registers a AssociationValue with the given saga. When the saga is committed, it can be found using the registered property.

Parameters:

property - The value to associate this saga with.

associateWith

protected void associateWith(String key,
                 String value)

Registers a AssociationValue with the given saga. When the saga is committed, it can be found using the registered property.

Parameters:

key - The key of the association value to associate this saga with.

value - The value of the association value to associate this saga with.

associateWith

protected void associateWith(String key,
                 Number value)

Registers a AssociationValue with the given saga. When the saga is committed, it can be found using the registered property.

Parameters:

key - The key of the association value to associate this saga with.

value - The value of the association value to associate this saga with.

removeAssociationWith

protected void removeAssociationWith(AssociationValue property)

Removes the given association from this Saga. When the saga is committed, it can no longer be found using the given association. If the given property wasn't registered with the saga, nothing happens.

Parameters:

property - the association value to remove from the saga.

removeAssociationWith

protected void removeAssociationWith(String key,
                         String value)

Removes the given association from this Saga. When the saga is committed, it can no longer be found using the given association value. If the given saga wasn't associated with given values, nothing happens.

Parameters:

key - The key of the association value to remove from this saga.

value - The value of the association value to remove from this saga.

removeAssociationWith

protected void removeAssociationWith(String key,
                         Number value)

Removes the given association from this Saga. When the saga is committed, it can no longer be found using the given association value. If the given saga wasn't associated with given values, nothing happens.

Parameters:

key - The key of the association value to remove from this saga.

value - The value of the association value to remove from this saga.
