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 Typedef Documentation

typedef vtkDataObjectAlgorithm vtkProgrammableDataObjectSource::Superclass

Reimplemented from vtkDataObjectAlgorithm.

Definition at line 51 of file vtkProgrammableDataObjectSource.h.

typedef void(* vtkProgrammableDataObjectSource::ProgrammableMethodCallbackType)(void *arg)

Signature definition for programmable method callbacks. Methods passed to SetExecuteMethod or SetExecuteMethodArgDelete must conform to this signature. The presence of this typedef is useful for reference and for external analysis tools, but it cannot be used in the method signatures in these header files themselves because it prevents the internal VTK wrapper generators from wrapping these methods.

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.

static int vtkProgrammableDataObjectSource::IsTypeOf ( const char * name ) [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 vtkDataObjectAlgorithm.

virtual int vtkProgrammableDataObjectSource::IsA ( const char * name ) [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 vtkDataObjectAlgorithm.

static vtkProgrammableDataObjectSource* vtkProgrammableDataObjectSource::SafeDownCast ( vtkObjectBase * o ) [static]

Reimplemented from vtkDataObjectAlgorithm.

virtual vtkObjectBase* vtkProgrammableDataObjectSource::NewInstanceInternal ( ) const [protected, virtual]

Reimplemented from vtkDataObjectAlgorithm.

vtkProgrammableDataObjectSource* vtkProgrammableDataObjectSource::NewInstance ( ) const

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.
