This driver class provide services around function
execution. One instance of this class is built for
the whole session. The driver is bound to the
DriverGUID in the DriverTable class.
It allows you to create classes which inherit from
this abstract class.
These subclasses identify the various algorithms
which can be applied to the data contained in the
attributes of sub-labels of a model.
A single instance of this class and each of its
subclasses is built for the whole session.

Public Member Functions | |
void | Init (const TDF_Label &L) |
Initializes the label L for this function prior to its execution. | |
TDF_Label | Label () const |
Returns the label of the driver for this function. | |
virtual void | Validate (TFunction_Logbook &log) const |
Validates labels of a function in <log>. This function is the one initialized in this function driver. Warning In regeneration mode, the solver must call this method even if the function is not executed. //! execution of function ===================== | |
virtual Standard_Boolean | MustExecute (const TFunction_Logbook &log) const |
Analyzes the labels in the logbook log. Returns true if attributes have been modified. If the function label itself has been modified, the function must be executed. | |
virtual Standard_Integer | Execute (TFunction_Logbook &log) const =0 |
Executes the function in this function driver and puts the impacted labels in the logbook log. //! arguments & results of functions ================================ | |
virtual void | Arguments (TDF_LabelList &args) const |
The method fills-in the list by labels, where the arguments of the function are located. | |
virtual void | Results (TDF_LabelList &res) const |
The method fills-in the list by labels, where the results of the function are located. | |
