ActionFactory
and Action
sub-typesThis package contains reference implementations of the various
Action
and ActionFactory
sub-type interfaces.
These are provided for convenience purposes. Clients are free to have
their own implementations of these interfaces should there be a need
for a different implementation.
A specific ActionFactory
sub type produces a
corresponding Action
sub type. For instance, a
FailureNotificationActionFactory
produces a
FailureNotificationAction
instance. An Action
sub type consumes a corresponding Signal
sub type. A
Signal
sub type stands for a specific group event. For instance,
the FailureNotificationAction
consumes a
FailureNotificationSignal
. GMS generates a specific
Signal
sub type's implementation in each member process for a given
group event and passes it to the corresponding Action
instance(s) in a separate thread.
