Hi. ted.
Thanks for your question.
In general, MQ is using to send messages among distribued servers in
enterprise environment.
I think that workflow you mentioned is workflow on the viewpoint of
integration.
On the other hands, Robust-Task handles general worlflow on one process or
one marchine.
For example, you can think of database transaction code which inserts data
to various tables. In this case, you might not choose MQ to implment that.
Robust-Task is similar to 'Apache commons chain' rather than MQ.
However, Robust-Task has more advantages than Apache commons chain.
First, Robust-Task is based on DSL(Domain Specific Langueage). It makes code
more READABLE. You can compare with the code style of Robust-Task and the
code style of Apache commons chain.
=== Robust-Task ===
new TaskChain()
.add(new GenesisCoupeTask())
.add(new TuscanyCoupeTask())
.add(new TiburonCoupeTask())
.execute();
=== Apache commons chain ===
public class SellVehicleChain extends ChainBase {
public SellVehicleChain() {
super();
addCommand(new GenesisCoupeTask());
addCommand(new TuscanyCoupeTask());
addCommand(new TiburonCoupeTask());
}
public static void main(String[] args) throws Exception {
Command process = new SellVehicleChain();
Context ctx = new ContextBase();
process.execute(ctx);
}
}
Second, Robust-Task provides Task decoration which can add special function
to Task as following.
=== LoggingCurrentTimeTask is run asynchronously ===
Method-Chaining style
new LoggingCurrentTimeTask()
.areWrappedByAsycer()
.execute();
Nested Function style
asyncer(
task(new LoggingCurrentTimeTask()),
).execute();
Last of all, Robust-Task provides combination among Task, Task-Chain and
Task-Decoration.
This can be called 'Potent combination'.
Using this feature, you can write flexible expression as following.
=== Combination among Task, Task-Chain and Task-Decoration ===
aspect(
before(new LoggingCurrentTimeTask()),
task(new TaskChain()
.add(new GenesisCoupeTask())
.add(new TuscanyCoupeTask())
.add(new TiburonCoupeTask())),
after(new AfterTask().areWrappedByRetryFailover().failover(new
FailoverTask()))
).areWrappedByAsycer().execute();
