Is there a way to name Principals in Subject's collection

So right now I create a new MutablePrincipalCollection

MutablePrincipalCollection principalCollection = new
SimplePrincipalCollection();
principalCollection.add(accountSecurity.getUsername(), getName());
principalCollection.add(accountSecurity.getUuid().toString(), getName());
String fingerprint = accountSecurity.getFingerprint();
if (fingerprint != null) {
  principalCollection.add(accountSecurity.getFingerprint(), getName());
}

But in order to get a particular value (They are all Strings) I need to
first call asList, then get it by index number. It would be nice if we could
name them. Then we could do something like

subject.getNamedPrincipal("Uuid")

Thanks

Mark

That last element might or might not be in the collection, which is why I
have to double check first.

Thanks, I just created a Utility class with static methods that take a
Subject.

Thanks

Hi Mark,

Not at the moment, but this is a high priority change for Shiro 2.x.  The
PrincipalCollection will likely be a Map so you can do things like
subject.getPrincipals().get("id");

In the meantime a potential fix (although hacky) is to create a wrapper
value class for the attribute you need, e.g. UuidPrincipal that just has
one method getUuid();  Then you can do a principalCollection.oneByType
lookup and unwrap the value.  Not pretty, but it works.  The Map approach
will be much nicer for sure!

HTH,
