I was thinking about using something similar to JNDI SearchControl mechanism. Then offset/limit and orderByName/ascending could be placed in two separate objects passed in an array. | Collection<Identity> findAssociatedIdentities(Group group, boolean inherited) throws IdentityException; | | Collection<Identity> findAssociatedIdentities(Group group, boolean inherited, IdentitySearchControl[] isc) throws IdentityException; | One benefit is to let add other parameters in the future, the other is easy discovery of supported features (is specific control supported). What kind of extensions do you have in mind btw?
