Detailed Description

generate source data object via a user-specified function

vtkProgrammableDataObjectSource is a source object that is programmable by the user. The output of the filter is a data object (vtkDataObject) which represents data via an instance of field data. To use this object, you must specify a function that creates the output.

Example use of this filter includes reading tabular data and encoding it as vtkFieldData. You can then use filters like vtkDataObjectToDataSetFilter to convert the data object to a dataset and then visualize it. 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

static vtkProgrammableDataObjectSource* vtkProgrammableDataObjectSource::New  )  [static]
 

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkDataObjectAlgorithm.

virtual const char* vtkProgrammableDataObjectSource::GetClassName  )  [virtual]
 

Reimplemented from vtkDataObjectAlgorithm.

static int vtkProgrammableDataObjectSource::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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkDataObjectAlgorithm.

virtual int vtkProgrammableDataObjectSource::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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkDataObjectAlgorithm.

static vtkProgrammableDataObjectSource* vtkProgrammableDataObjectSource::SafeDownCast vtkObject o  )  [static]
 

Reimplemented from vtkDataObjectAlgorithm.

void vtkProgrammableDataObjectSource::PrintSelf ostream &  os,
vtkIndent  indent
[virtual]
 

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkDataObjectAlgorithm.

void vtkProgrammableDataObjectSource::SetExecuteMethod void(*)(void *)  f,
void *  arg
 

Specify the function to use to generate the output data object. Note that the function takes a single (void *) argument.

void vtkProgrammableDataObjectSource::SetExecuteMethodArgDelete void(*)(void *)  f  ) 
 

Set the arg delete method. This is used to free user memory.

virtual int vtkProgrammableDataObjectSource::RequestData vtkInformation ,
vtkInformationVector **  ,
vtkInformationVector
[protected, virtual]
 

This is called by the superclass. This is the method you should override.

Reimplemented from vtkDataObjectAlgorithm.
