Class ServicePermission

java.lang.Object
java.security.Permission
javax.security.auth.kerberos.ServicePermission
All Implemented Interfaces:
Serializable, Guard
@Deprecated(since="25", forRemoval=true) public final class ServicePermission extends Permission implements Serializable
Deprecated, for removal: This API element is subject to removal in a future version.
This permission cannot be used for controlling access to resources as the Security Manager is no longer supported.
A ServicePermission contains a service principal name and a list of actions which specify the context the credential can be used within.

The service principal name is the canonical name of the KerberosPrincipal supplying the service, that is the KerberosPrincipal represents a Kerberos service principal. This name is treated in a case sensitive manner. An asterisk may appear by itself, to signify any service principal.

The possible actions are: 

   initiate -              allow the caller to use the credential to
                           initiate a security context with a service
                           principal.

   accept -                allow the caller to use the credential to
                           accept security context as a particular
                           principal.

ServicePermission

public ServicePermission(String servicePrincipal, String action)

action - the action string

Method Details

implies

public boolean implies(Permission p)
Deprecated, for removal: This API element is subject to removal in a future version.
Checks if this Kerberos service permission object "implies" the specified permission.

More specifically, this method returns true if all the following are true (and returns false if any of them are not):

  • p is an instanceof ServicePermission,
  • p's actions are a proper subset of this ServicePermission's actions,
  • p's name is equal to this ServicePermission's name or this ServicePermission's name is "*".
Specified by:
implies in class Permission
Parameters:
p - the permission to check against.
Returns:
true if the specified permission is implied by this object, false if not.

equals

public boolean equals(Object obj)
Deprecated, for removal: This API element is subject to removal in a future version.
Checks two ServicePermission objects for equality.
Specified by:
equals in class Permission
Parameters:
obj - the object to test for equality with this object.
Returns:
true if obj is a ServicePermission, and has the same service principal, and actions as this ServicePermission object.

hashCode

public int hashCode()
Deprecated, for removal: This API element is subject to removal in a future version.
Returns the hash code value for this object.
Specified by:
hashCode in class Permission
Returns:
the hash code value for this object
See Also:

getActions

public String getActions()
Deprecated, for removal: This API element is subject to removal in a future version.
Returns the canonical string representation of the actions. Always returns present actions in the following order: initiate, accept.
Specified by:
getActions in class Permission
Returns:
the actions of this Permission.

newPermissionCollection

public PermissionCollection newPermissionCollection()
Deprecated, for removal: This API element is subject to removal in a future version.
Returns a PermissionCollection object for storing ServicePermission objects.
ServicePermission objects must be stored in a manner that allows them to be inserted into the collection in any order, but that also enables the PermissionCollection implies method to be implemented in an efficient (and consistent) manner.
Overrides:
newPermissionCollection in class Permission
Returns:
a new PermissionCollection object suitable for storing ServicePermissions.
