is
---Category: Static methods
-- ==============
NewFunction (myclass;
L : Label from TDF;
ID : GUID from Standard)
---Purpose: Sets a new function attached to a label <L> with <ID>.
-- It creates a new TFunction_Function attribute initialized by the <ID>,
-- a new TFunction_GraphNode with an empty list of dependencies and
-- the status equal to TFunction_ES_WrongDefinition.
-- It registers the function in the scope of functions for this document.
returns Boolean from Standard;
DeleteFunction (myclass;
L : Label from TDF)
---Purpose: Deletes a function attached to a label <L>.
-- It deletes a TFunction_Function attribute and a TFunction_GraphNode.
-- It deletes the functions from the scope of function of this document.
returns Boolean from Standard;
UpdateDependencies (myclass;
Access : Label from TDF)
---Purpose: Updates dependencies for all functions of the scope.
-- It returns false in case of an error.
returns Boolean from Standard;
---Category: Instant methods
-- ===============
Create
---Purpose: An empty constructor.
returns IFunction from TFunction;
Create (L : Label from TDF)
---Purpose: A constructor.
-- Initializes the interface by the label of function.
returns IFunction from TFunction;
Init (me : in out;
L : Label from TDF);
---Purpose: Initializes the interface by the label of function.
Label (me)
---C++: return const &
---Purpose: Returns a label of the function.
returns Label from TDF;
UpdateDependencies (me)
---Purpose: Updates the dependencies of this function only.
returns Boolean from Standard;
---Category: Driver methods
-- ==============
Arguments (me; args : out LabelList from TDF);
---Purpose: The method fills-in the list by labels,
-- where the arguments of the function are located.
Results (me; res : out LabelList from TDF);
---Purpose: The method fills-in the list by labels,
-- where the results of the function are located.
---Category: Graph node methods
-- ==================
GetPrevious (me; prev : out LabelList from TDF);
---Purpose: Returns a list of previous functions.
GetNext (me; prev : out LabelList from TDF);
---Purpose: Returns a list of next functions.
GetStatus (me)
---Purpose: Returns the execution status of the function.
returns ExecutionStatus from TFunction;
SetStatus (me; status : ExecutionStatus from TFunction);
---Purpose: Defines an execution status for a function.
---Category: Scope methods
-- =============
GetAllFunctions (me)
---Purpose: Returns the scope of all functions.
---C++: return const &
returns DoubleMapOfIntegerLabel from TFunction;
GetLogbook (me)
---Purpose: Returns the Logbook - keeper of modifications.
---C++: return &
returns Logbook from TFunction;
---Categery: Internal methods (direct access)
-- ================================
GetDriver (me; thread : Integer from Standard = 0)
---Purpose: Returns a driver of the function.
returns Driver from TFunction;
GetGraphNode (me)
---Purpose: Returns a graph node of the function.
returns GraphNode from TFunction;
