      Returns:
      the canonical string representation of the actions.
    • implies

      public boolean implies(Permission permission)
      Checks if this CardPermission object implies the specified permission. That is the case, if and only if
      • permission is an instance of CardPermission,

      • permission's actions are a proper subset of this object's actions, and

      • this object's getName() method is either * or equal to permission's name.

      Specified by:
      implies in class Permission
      Parameters:
      permission - the permission to check against
      Returns:
      true if and only if this CardPermission object implies the specified permission.
    • equals

      public boolean equals(Object obj)
      Compares the specified object with this CardPermission for equality. This CardPermission is equal to another Object object, if and only if
      • object is an instance of CardPermission,

      • this.getName() is equal to ((CardPermission)object).getName(), and

      • this.getActions() is equal to ((CardPermission)object).getActions().

      Specified by:
