Detailed Description

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

vtkPassInputTypeAlgorithm is a convenience class to make writing algorithms easier. It is also designed to help transition old algorithms to the new pipeline architecture. There 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 DataObject. If that isn't the case then please override this method in your subclass. This class breaks out the downstream requests into separate 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.

virtual int vtkPassInputTypeAlgorithm::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.

Reimplemented in vtkTemporalStatistics, and vtkAssignAttribute.

virtual int vtkPassInputTypeAlgorithm::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.

Reimplemented in vtkTemporalStatistics.

Definition at line 144 of file vtkPassInputTypeAlgorithm.h.

virtual int vtkPassInputTypeAlgorithm::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 in vtkTemporalStatistics.

virtual int vtkPassInputTypeAlgorithm::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.
