Detailed Description

Superclass for algorithms that produce output of the same type as input.

vtkDataSetAlgorithm is a convenience class to make writing algorithms easier. It is also designed to help transition old algorithms to the new pipeline architecture. Ther are some assumptions and defaults made by this class you should be aware of. This class defaults such that your filter will have one input port and one output port. If that is not the case simply change it with SetNumberOfInputPorts etc. See this classes contstructor for the default. This class also provides a FillInputPortInfo method that by default says that all inputs will be DataSet. If that isn't the case then please override this method in your subclass. This class breaks out the downstream requests into seperate functions such as RequestDataObject RequestData and RequestInformation. The default implementation of RequestDataObject will create an output data of the same type as the input.

Reimplemented from vtkAlgorithm.

static int vtkDataSetAlgorithm::IsTypeOf ( const char *  type)
static
virtual int vtkDataSetAlgorithm::IsA ( const char *  name)

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 vtkAlgorithm.

static
void vtkDataSetAlgorithm::PrintSelf ( ostream &  os,

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 vtkAlgorithm.

vtkDataSet* vtkDataSetAlgorithm::GetOutput ( )

Get the output data object for a port on this algorithm.

vtkDataSet* vtkDataSetAlgorithm::GetOutput ( int  )

Get the output data object for a port on this algorithm.

vtkDataObject* vtkDataSetAlgorithm::GetInput ( )

Get the input data object. This method is not recommended for use, but lots of old style filters use it.

Get the output as vtkPolyData.

vtkStructuredPoints* vtkDataSetAlgorithm::GetStructuredPointsOutput ( )

Get the output as vtkStructuredPoints.

vtkImageData* vtkDataSetAlgorithm::GetImageDataOutput ( )

vtkRectilinearGrid* vtkDataSetAlgorithm::GetRectilinearGridOutput ( )

Get the output as vtkRectilinearGrid.

void vtkDataSetAlgorithm::SetInput ( vtkDataObject )

Set an input of this algorithm. You should not override these methods because they are not the only way to connect a pipeline. Note that these methods support old-style pipeline connections. When writing new code you should use the more general vtkAlgorithm::SetInputConnection(). These methods transform the input index to the input port index, not an index of a connection within a single port.

void vtkDataSetAlgorithm::SetInput ( int  ,
vtkDataObject  
)

Set an input of this algorithm. You should not override these methods because they are not the only way to connect a pipeline. Note that these methods support old-style pipeline connections. When writing new code you should use the more general vtkAlgorithm::SetInputConnection(). These methods transform the input index to the input port index, not an index of a connection within a single port.

void vtkDataSetAlgorithm::SetInput ( vtkDataSet )

Set an input of this algorithm. You should not override these methods because they are not the only way to connect a pipeline. Note that these methods support old-style pipeline connections. When writing new code you should use the more general vtkAlgorithm::SetInputConnection(). These methods transform the input index to the input port index, not an index of a connection within a single port.

void vtkDataSetAlgorithm::SetInput ( int  ,
vtkDataSet  
)

Set an input of this algorithm. You should not override these methods because they are not the only way to connect a pipeline. Note that these methods support old-style pipeline connections. When writing new code you should use the more general vtkAlgorithm::SetInputConnection(). These methods transform the input index to the input port index, not an index of a connection within a single port.

void vtkDataSetAlgorithm::AddInput ( vtkDataObject )

Add an input of this algorithm. Note that these methods support old-style pipeline connections. When writing new code you should use the more general vtkAlgorithm::AddInputConnection(). See SetInput() for details.

void vtkDataSetAlgorithm::AddInput ( vtkDataSet )

Add an input of this algorithm. Note that these methods support old-style pipeline connections. When writing new code you should use the more general vtkAlgorithm::AddInputConnection(). See SetInput() for details.

void vtkDataSetAlgorithm::AddInput ( int  ,
vtkDataSet  
)

Add an input of this algorithm. Note that these methods support old-style pipeline connections. When writing new code you should use the more general vtkAlgorithm::AddInputConnection(). See SetInput() for details.

void vtkDataSetAlgorithm::AddInput ( int  ,

virtual int vtkDataSetAlgorithm::ProcessRequest ( vtkInformation request,
vtkInformationVector **  inputVector,
vtkInformationVector outputVector 
)
virtual

see vtkAlgorithm for details

Reimplemented from vtkAlgorithm.

virtual int vtkDataSetAlgorithm::RequestInformation ( vtkInformation ,
vtkInformationVector **  ,
vtkInformationVector  
)
inlineprotectedvirtual

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.

Definition at line 126 of file vtkDataSetAlgorithm.h.

virtual int vtkDataSetAlgorithm::RequestUpdateExtent ( vtkInformation ,
vtkInformationVector **  ,
vtkInformationVector  
)
inlineprotectedvirtual

This is called within ProcessRequest when each filter in the pipeline decides what portion of its input is needed to create the portion of its output that the downstream filter asks for. This happens during the second pass in the pipeline execution process.

Definition at line 136 of file vtkDataSetAlgorithm.h.

virtual int vtkDataSetAlgorithm::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.

virtual int vtkDataSetAlgorithm::RequestData ( vtkInformation ,
vtkInformationVector **  ,
vtkInformationVector  
)
inlineprotectedvirtual

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.

Definition at line 163 of file vtkDataSetAlgorithm.h.

virtual int vtkDataSetAlgorithm::FillOutputPortInformation ( int  port,
vtkInformation info 
)
protectedvirtual

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

Reimplemented from vtkAlgorithm.

virtual int vtkDataSetAlgorithm::FillInputPortInformation ( int  port,
vtkInformation info 
)
