Detailed Description

generate source dataset via a user-specified function

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 Typedef Documentation

typedef vtkDataSetAlgorithm vtkProgrammableSource::Superclass

Definition at line 59 of file vtkProgrammableSource.h.

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

Signature definition for programmable method callbacks. Methods passed to SetExecuteMethod, SetExecuteMethodArgDelete or SetRequestInformationMethod 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.

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.

const

void vtkProgrammableSource::SetExecuteMethod	(	void(*)(void *)	f,
		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(*)(void *)

f

)

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

void vtkProgrammableSource::SetRequestInformationMethod

(

void(*)(void *)

f

)

Specify the function to use to fill in information about the source data.

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.

vtkStructuredPoints* vtkProgrammableSource::GetStructuredPointsOutput

(

)

Get the output as a concrete type.

vtkStructuredGrid* vtkProgrammableSource::GetStructuredGridOutput

(

)

Get the output as a concrete type.

vtkUnstructuredGrid* vtkProgrammableSource::GetUnstructuredGridOutput

(

)

Get the output as a concrete type.

vtkRectilinearGrid* vtkProgrammableSource::GetRectilinearGridOutput

(

)

Get the output as a concrete type.

virtual int vtkProgrammableSource::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 vtkDataSetAlgorithm.

virtual int vtkProgrammableSource::RequestDataObject ( vtkInformation *  request, vtkInformationVector **  inputVector, vtkInformationVector *  outputVector  )

protectedvirtual

This is called within ProcessRequest to when a request asks the algorithm to create empty output data objects. This typically happens early on in the execution of the pipeline. The default behavior is to create an output DataSet of the same type as the input for each output port. This method can be overridden to change the output data type of an algorithm. This happens in the third pass of the pipeline execution.

Reimplemented from vtkDataSetAlgorithm.

virtual int vtkProgrammableSource::RequestInformation ( vtkInformation *  , vtkInformationVector **  , vtkInformationVector *    )

protectedvirtual

This is called within ProcessRequest when a request asks for Information. Typically an algorithm provides whatever lightweight information about its output that it can here without doing any lengthy computations. This happens in the first pass of the pipeline execution.

Reimplemented from vtkDataSetAlgorithm.
