[jboss-user] [JBoss Seam] - Re: roles redirecting methods
Hi Shane,
Sorry if my last mail wasn't clear. I'll explain the idea by the mean of a
frequent example:
Let's imagine we have an application with 3 rules: client, commercial and
administrator : the client can see only its orders, the commercial can only see the orders
of his clients and the administrator can see all orders:
This example can only be developed like this :
| doCommonCode();
| if( rule="commercial" ) {
| doCommercial();
| } else if( rule="client" ) {
| doClient();
| } else if( rule="administrator" ) {
| doAdministrator();
| }
The new seam authorization mecanism cant' do this simply beacuse the @Restricted
annotation is binary (not a switch). These if else blocks become very frequent and reduce
code readability.
The solution I sent is just a proposition: It attempts to add to the annotations the
responsibility to redirect to the business rule case method. Here's how I imagine it:
@RuleSensible comes as the @Override annotation : it just enforces readability and code
changes safety : it informs this method is a rule switch. (inside the method body comes
the common code to all cases)
@RuleCase( method="switchMethodName ) is there to say : this is a switch case for the
given method
and finally @Restricted comes to say which rule case must be handled by the annotated
method.
So here was my idea, I hope you'll like it.
