Create a GroupPrincipalCallback to establish the container's representation of the corresponding group principals within the Subject.- Parameters:
s
- The Subject in which the container will create group principals.g
- An array of Strings, where each element contains the name of a group that will be used to create a corresponding group principal within the Subject.When a null value is passed to the g argument, the handler will establish the container's representation of no group principals within the Subject. Otherwise, the handler's processing of this callback is additive, yielding the union (without duplicates) of the principals existing within the Subject, and those created with the names occuring within the argument array. The CallbackHandler will define the type of the created principals.
