vtkGenericDataSetAlgorithm Class Reference
#include <vtkGenericDataSetAlgorithm.h>
Detailed Description
Objects that generate adapted data sets.vtkGenericDataSetAlgorithm 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 constructor for the default. This class also provides a FillInputPortInfo method that by default says that all inputs will be GenericDataSet. 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 ExecuteData and ExecuteInformation. For new algorithms you should implement RequestData( request, inputVec, outputVec) but for older filters there is a default implementation that calls the old ExecuteData(output) signature, for even older filters that don;t implement ExecuteData the default implementation calls the even older Execute() signature.

| virtual const char* vtkGenericDataSetAlgorithm::GetClassName | ( | ) | [virtual] |
Reimplemented from vtkAlgorithm.
| static int vtkGenericDataSetAlgorithm::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 vtkAlgorithm.
| virtual int vtkGenericDataSetAlgorithm::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 vtkAlgorithm.

Reimplemented from vtkAlgorithm.
| void vtkGenericDataSetAlgorithm::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 vtkAlgorithm.
| vtkGenericDataSet* vtkGenericDataSetAlgorithm::GetOutput | ( | ) |
Get the output data object for a port on this algorithm.
| vtkGenericDataSet* vtkGenericDataSetAlgorithm::GetOutput | ( | int | ) |
Get the output data object for a port on this algorithm.
| virtual void vtkGenericDataSetAlgorithm::SetOutput | ( | vtkDataObject * | d | ) | [virtual] |
Get the output data object for a port on this algorithm.

| vtkGenericDataSet* vtkGenericDataSetAlgorithm::GetGenericDataSetInput | ( | int | port | ) |
| void vtkGenericDataSetAlgorithm::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 vtkGenericDataSetAlgorithm::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 vtkGenericDataSetAlgorithm::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 vtkGenericDataSetAlgorithm::AddInput | ( | int | , | |
| 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.
