Detailed Description

a user-programmable filter

vtkProgrammableFilter is a filter that can be programmed by the user. To use the filter you define a function that retrieves input of the correct type, creates data, and then manipulates the output of the filter. Using this filter avoids the need for subclassing - and the function can be defined in an interpreter wrapper language such as Tcl or Java.

The trickiest part of using this filter is that the input and output methods are unusual and cannot be compile-time type checked. Instead, as a user of this filter it is your responsibility to set and get the correct input and output types.

Warning
The filter correctly manages modified time and network execution in most cases. However, if you change the definition of the filter function, you'll want to send a manual Modified() method to the filter to force it to reexecute.

Member Typedef Documentation

Definition at line 58 of file vtkProgrammableFilter.h.

typedef void(* vtkProgrammableFilter::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.

static vtkProgrammableFilter* vtkProgrammableFilter::New ( )
static
static int vtkProgrammableFilter::IsTypeOf ( const char *  type)
static
virtual int vtkProgrammableFilter::IsA ( const char *  type)
virtual

Reimplemented from vtkPassInputTypeAlgorithm.

static vtkProgrammableFilter* vtkProgrammableFilter::SafeDownCast ( vtkObjectBase *  o)
static
virtual vtkObjectBase* vtkProgrammableFilter::NewInstanceInternal ( ) const
protectedvirtual

Reimplemented from vtkPassInputTypeAlgorithm.

vtkProgrammableFilter* vtkProgrammableFilter::NewInstance ( ) const
void vtkProgrammableFilter::PrintSelf ( ostream &  os,
vtkIndent  indent 
)
void vtkProgrammableFilter::SetExecuteMethod ( void(*)(void *)  f,
void *  arg 
)

Specify the function to use to operate on the point attribute data. Note that the function takes a single (void *) argument.

void vtkProgrammableFilter::SetExecuteMethodArgDelete ( void(*)(void *)  f)

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

vtkPolyData* vtkProgrammableFilter::GetPolyDataInput ( )

Get the input as a concrete type. This method is typically used by the writer of the filter function to get the input as a particular type (i.e., it essentially does type casting). It is the users responsibility to know the correct type of the input data.

vtkStructuredPoints* vtkProgrammableFilter::GetStructuredPointsInput ( )

Get the input as a concrete type.

vtkStructuredGrid* vtkProgrammableFilter::GetStructuredGridInput ( )

Get the input as a concrete type.

vtkUnstructuredGrid* vtkProgrammableFilter::GetUnstructuredGridInput ( )

Get the input as a concrete type.

vtkRectilinearGrid* vtkProgrammableFilter::GetRectilinearGridInput ( )

Get the input as a concrete type.

vtkGraph* vtkProgrammableFilter::GetGraphInput ( )

Get the input as a concrete type.

vtkTable* vtkProgrammableFilter::GetTableInput ( )

Get the input as a concrete type.

virtual void vtkProgrammableFilter::SetCopyArrays ( bool  )
virtual

When CopyArrays is true, all arrays are copied to the output iff input and output are of the same type. False by default.

virtual bool vtkProgrammableFilter::GetCopyArrays ( )
virtual

When CopyArrays is true, all arrays are copied to the output iff input and output are of the same type. False by default.

virtual void vtkProgrammableFilter::CopyArraysOn ( )
virtual

When CopyArrays is true, all arrays are copied to the output iff input and output are of the same type. False by default.

virtual void vtkProgrammableFilter::CopyArraysOff ( )
virtual

When CopyArrays is true, all arrays are copied to the output iff input and output are of the same type. False by default.

int vtkProgrammableFilter::RequestData ( vtkInformation *  ,
vtkInformationVector **  ,
vtkInformationVector *   
)
protectedvirtual

This is called within ProcessRequest when a request asks the algorithm to do its work. This is the method you should override to do whatever the algorithm is designed to do. This happens during the fourth pass in the pipeline execution process.

Reimplemented from vtkPassInputTypeAlgorithm.

virtual int vtkProgrammableFilter::FillInputPortInformation ( int  port,
vtkInformation *  info 
)
protectedvirtual

Fill the input port information objects for this algorithm. This is invoked by the first call to GetInputPortInformation for each port so subclasses can specify what they can handle.

Reimplemented from vtkPassInputTypeAlgorithm.
