vtkProgrammableSource is a source object that is programmable by the user. To use this object, you must specify a function that creates the output. It is possible to generate an output dataset of any (concrete) type; it is up to the function to properly initialize and define the output. Typically, you use one of the methods to get a concrete output type (e.g., GetPolyDataOutput() or GetStructuredPointsOutput()), and then manipulate the output in the user-specified function.
Example use of this include writing a function to read a data file or interface to another system. (You might want to do this in favor of deriving a new class.) Another important use of this class is that it allows users of interpreters (e.g., Tcl or Java) the ability to write source objects without having to recompile C++ code or generate new libraries.

Member Function Documentation
| vtkProgrammableSource* vtkProgrammableSource::New |
( |
|
) |
[static] |
|
|
|
Instantiate object with no start, end, or progress methods.
Reimplemented from vtkSource. |
| virtual const char* vtkProgrammableSource::GetClassName |
( |
|
) |
[virtual] |
|
|
|
Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.
Reimplemented from vtkSource. |
| int vtkProgrammableSource::IsTypeOf |
( |
const char * |
type |
) |
[static] |
|
|
|
Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.
Reimplemented from vtkSource. |
| virtual int vtkProgrammableSource::IsA |
( |
const char * |
type |
) |
[virtual] |
|
|
|
Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.
Reimplemented from vtkSource. |
| vtkProgrammableSource* vtkProgrammableSource::SafeDownCast |
( |
vtkObject * |
o |
) |
[static] |
|
|
|
Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.
Reimplemented from vtkSource. |
| void vtkProgrammableSource::SetExecuteMethod |
( |
void(* |
f)(void *), |
|
|
void * |
arg |
|
) |
|
|
|
|
Specify the function to use to generate the source data. Note that the function takes a single (void *) argument. |
| void vtkProgrammableSource::SetExecuteMethodArgDelete |
( |
void(* |
f)(void *) |
) |
|
|
|
|
Set the arg delete method. This is used to free user memory. |
| vtkPolyData* vtkProgrammableSource::GetPolyDataOutput |
( |
|
) |
|
|
|
|
Get the output as a concrete type. This method is typically used by the writer of the source function to get the output as a particular type (i.e., it essentially does type casting). It is the users responsibility to know the correct type of the output data. |
