All Implemented Interfaces:
Callback
public class GroupPrincipalCallback
extends Object
implements Callback
Callback establishing group principals within the argument subject.

This callback is intended to be called by a serverAuthModule during its validateRequest processing.

  • Constructor Details

    • GroupPrincipalCallback

      public GroupPrincipalCallback​(Subject subject, String[] groups)
      Create a GroupPrincipalCallback to establish the container's representation of the corresponding group principals within the Subject.

      When a null value is passed to the groups 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 occurring within the argument array. The CallbackHandler will define the type of the created principals.

      Parameters:
      subject - The Subject in which the container will create group principals.
      groups - 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.

  • Method Details

    • getSubject

      public Subject getSubject()
      Get the Subject in which the handler will establish the group principals.
      Returns:
      The subject.

    • getGroups

      public String[] getGroups()
      Get the array of group names.

      When the return value is null, 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 created with the names in the returned array and those existing within the Subject.

      Returns:
      Null, or an array containing 0 or more String group names.
