Method Detail

### createRolePolicy

    public static void createRolePolicy(RolePolicyItem aRolePolicyItem)
                                 throws PolicyExistsException,
                                        PolicyCreateException,
                                        PolicyNotFoundException,
                                        PolicyException

  Creates a new role policy. A role policy may be predicated on one or more user ids, user group names, and/or a custom predicate. Prior to trying to persist a new role policy, this method will check the RolePolicyItem to insure all mandatory fields have been initialized. Mandatory fields are: 1) aResourceScope, 2) (depending on the value of aResourceScope) anEntAppName, aWebAppName, aResourceId, 3) (at least one of) aUserList, aGroupList, aRoleSegmentName, 4) aRoleName.

  Parameters:
    `aRolePolicyItem` - The object containing the required and optional role policy attributes
  Throws:
    `InvalidArgsException`
    `PolicyExistsException`
    `PolicyCreateException`
    `PolicyNotFoundException`
    `PolicyException`

### getRolePolicy

    public static RolePolicyItem getRolePolicy(RolePolicyItem aRolePolicyItem)
                                        throws PolicyNotFoundException,
                                               PolicyException

  Retrieves an existing role policy. Prior to trying to retrieve the role policy, this method will check the RolePolicyItem to insure all mandatory fields have been initialized. Mandatory fields are: 1) aResourceScope, 2) (depending on the value of aResourceScope) anEntAppName, aWebAppName, aResourceId, 3) aRoleName.

  The returned RolePolicyItem may be used to hold local updates to user lists, group lists, and role segment name changes prior to persisting changes using the setRolePolicy() method.

  Parameters:
    `aRolePolicyItem` - The object containing the required and optional role policy attributes
  Returns:
    RolePolicyItem or null if none found
  Throws:
    `InvalidArgsException`
    `PolicyNotFoundException`
    `PolicyException`

### setRolePolicy

    public static void setRolePolicy(RolePolicyItem aRolePolicyItem)
                              throws PolicyExpressionException,
                                     PolicyNotFoundException,
                                     PolicyExistsException,
                                     PolicyCreateException,
                                     PolicyException

  Updates an existing role policy. Prior to trying to update the role policy, this method will check the RolePolicyItem to insure all mandatory fields have been initialized. Mandatory fields are: 1) aResourceScope, 2) (depending on the value of aResourceScope) anEntAppName, aWebAppName, aResourceId, 3) (at least one of) aUserList, aGroupList, aRoleSegmentName, 4) aRoleName.

  Note that if the aRolePolicyItem instance was retrieved using getRolePolicy(), all mandatory fields will already be initialized. The only fields that are updateable in the persisted role policy are the aUserList, aGroupList, and aRoleSegmentName.

  Parameters:
    `aRolePolicyItem` - The object containing the required and optional role policy attributes
  Throws:
    `InvalidArgsException`
    `PolicyExpressionException`
    `PolicyNotFoundException`
    `PolicyExistsException`
    `PolicyCreateException`
    `PolicyException`

### removeRolePolicy

    public static void removeRolePolicy(RolePolicyItem aRolePolicyItem)
                                 throws PolicyRemoveException,
                                        PolicyNotFoundException

  Removes an existing role policy. Prior to trying to remove the role policy, this method will check the RolePolicyItem to insure all mandatory fields have been initialized. Mandatory fields are: 1) aResourceScope, 2) (depending on the value of aResourceScope) anEntAppName, aWebAppName, aResourceId, 3) aRoleName. This method should not be called if there are security policies in existence that refer to the role to be deleted. Check for policy references first using `rolePolicyHasRefs()`.

  Parameters:
    `aRolePolicyItem` - The object containing the required role policy attributes
  Throws:
    `InvalidArgsException`
    `PolicyNotFoundException`
    `PolicyRemoveException`

### rolePolicyExists

    public static boolean rolePolicyExists(RolePolicyItem aRolePolicyItem)

  Tests for an existing role policy. This method will check the RolePolicyItem to insure all mandatory fields have been initialized. Mandatory fields are: 1) aResourceScope, 2) (depending on the value of aResourceScope) anEntAppName, aWebAppName, aResourceId, 3) aRoleName.

  Parameters:
    `aRolePolicyItem` - The object containing the required role policy attributes
  Returns:
    True if policy exists, otherwise false
  Throws:
    `InvalidArgsException`

### listRolesForResource

    public static Object[][] listRolesForResource(int aResourceScope,
                                                  String anEntAppName,
                                                  String aWebAppName,
                                                  String aResourceId)

  Finds all available role policies given a resourceId and a scope. Instead of just returning role policies associated at the resource Id (leaf) node, this method may be used to get a full list of role policy names associated with the resource taxonomy given as an input scope.

  Parameters:
    `aResourceScope` - A global, enterprise, webapp, or application scope defined by the EntitlementConstants class.
    `anEntAppName` - Enterprise Application name
    `aWebAppName` - Webapp name. Unused for Global role inheritance
    `aResourceId` - Application defined resource ID
  Returns:
    An 2D array of all the role policy names that have been persisted against the given resource id and those also inherited by the resource given its taxonomy. The zero'th element [i][0] contains the P13nResource where the String role name (elements [i][1..n]) were found.

### listRolesForResource

    public static String[] listRolesForResource(String anEntAppName,
                                                String aWebAppName,
                                                String aResourceId)

  Finds all available role policies given a resourceId. Returns role policies associated at the resource Id node, only (i.e. the leaf role scope).

  Parameters:
    `anEntAppName` - Enterprise Application name
    `aResourceId` - Application defined resource ID
    `aWebAppName` - Webapp name. Unused for Global role inheritance
  Returns:
    An 2D array of all the role policy names that have been persisted against the given resource id and those also inherited by the resource given its taxonomy. The zero'th element [i][0] contains the P13nResource where the String role name (elements [i][1..n]) were found.

### rolePolicyHasRefs

    public static boolean rolePolicyHasRefs(RolePolicyItem aRolePolicyItem)
                                     throws PolicyRefException

  Checks whether a given Role Policy is currently referenced (i.e. being used by) any Security Policies.

  Parameters:
    `aRolePolicyItem` - The object containing the required and optional role policy attributes
  Returns:
    boolean True if any Security Policies reference the Role Policy
  Throws:
    `InvalidArgsException`
    `PolicyRefException`
