RLMPermission

@interface RLMPermission : RLMObject

A permission which can be applied to a Realm, Class, or specific Object.

Permissions are applied by adding the permission to the RLMRealmPermission singleton object, the RLMClassPermission object for the desired class, or to a user-defined RLMArray property on a specific Object instance. The meaning of each of the properties of RLMPermission depend on what the permission is applied to, and so are left undocumented here. See RLMRealmPrivileges, RLMClassPrivileges, and RLMObjectPrivileges for details about what each of the properties mean when applied to that type.

  • The Role which this Permission applies to. All users within the Role are granted the permissions specified by the fields below any objects/classes/realms which use this Permission.

    This property cannot be modified once set.

  • Returns the Permission object for the named Role in the array, creating it if needed.

    This function should be used in preference to manually querying the array for the applicable Permission as it ensures that there is exactly one Permission for the given Role in the array, merging duplicates or creating and adding new ones as needed.

    Declaration

    Objective-C

    + (nonnull RLMPermission *)
permissionForRoleNamed:(nonnull NSString *)roleName
               inArray:
                   (nonnull RLMArray<RLMPermission *><RLMPermission> *)array;

  • Returns the Permission object for the named Role on the Realm, creating it if needed.

    This function should be used in preference to manually querying for the applicable Permission as it ensures that there is exactly one Permission for the given Role on the Realm, merging duplicates or creating and adding new ones as needed.

    Declaration

    Objective-C

    + (nonnull RLMPermission *)permissionForRoleNamed:(nonnull NSString *)roleName
                                          onRealm:(nonnull RLMRealm *)realm;

  • Returns the Permission object for the named Role on the Class, creating it if needed.

    This function should be used in preference to manually querying for the applicable Permission as it ensures that there is exactly one Permission for the given Role on the Class, merging duplicates or creating and adding new ones as needed.

    Declaration

    Objective-C

    + (nonnull RLMPermission *)permissionForRoleNamed:(nonnull NSString *)roleName
                                          onClass:(nonnull Class)cls

  • Returns the Permission object for the named Role on the named class, creating it if needed.

    This function should be used in preference to manually querying for the applicable Permission as it ensures that there is exactly one Permission for the given Role on the Class, merging duplicates or creating and adding new ones as needed.

    Declaration

    Objective-C

    + (nonnull RLMPermission *)permissionForRoleNamed:(nonnull NSString *)roleName
                                     onClassNamed:(nonnull NSString *)className

  • Returns the Permission object for the named Role on the object, creating it if needed.

    This function should be used in preference to manually querying for the applicable Permission as it ensures that there is exactly one Permission for the given Role on the Realm, merging duplicates or creating and adding new ones as needed.

    The given object must have a RLMArray property defined on it. If more than one such property is present, the first will be used.

    Declaration

    Objective-C

    + (nonnull RLMPermission *)permissionForRoleNamed:(nonnull NSString *)roleName
