vtkNGramExtraction Class Reference
#include <vtkNGramExtraction.h>
Detailed Description
Converts a collection of tokens into a collection of N-grams.Given a table containing tokens, generates a table containing N-grams.
Inputs: Input port 0: (required) A vtkTable containing document, begin, end, and text columns.
Outputs: Output port 0: A vtkTable containing "document", "begin", "end", "type", and "text" columns.
Use SetInputArrayToProcess(0, ...) to specify the "document" array. Use SetInputArrayToProcess(1, ...) to specify the "begin" array. Use SetInputArrayToProcess(2, ...) to specify the "end" array. Use SetInputArrayToProcess(3, ...) to specify the "text" array.

| static vtkNGramExtraction* vtkNGramExtraction::New | ( | ) | [static] |
Create an object with Debug turned off, modified time initialized to zero, and reference counting on.
Reimplemented from vtkTableAlgorithm.
| virtual const char* vtkNGramExtraction::GetClassName | ( | ) | [virtual] |
Reimplemented from vtkTableAlgorithm.
| static int vtkNGramExtraction::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 vtkTableAlgorithm.
| virtual int vtkNGramExtraction::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 vtkTableAlgorithm.
| static vtkNGramExtraction* vtkNGramExtraction::SafeDownCast | ( | vtkObject * | o | ) | [static] |
Reimplemented from vtkTableAlgorithm.
| void vtkNGramExtraction::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 vtkTableAlgorithm.
| virtual void vtkNGramExtraction::SetN | ( | vtkIdType | ) | [virtual] |
Controls the type of N-gram to produce. Default: 1 (unigrams).
| virtual vtkIdType vtkNGramExtraction::GetN | ( | ) | [virtual] |
Controls the type of N-gram to produce. Default: 1 (unigrams).
| virtual int vtkNGramExtraction::RequestData | ( | vtkInformation * | request, | |
| vtkInformationVector ** | inputVector, | |||
| vtkInformationVector * | outputVector | |||
| ) | [protected, virtual] |
This is called by the superclass. This is the method you should override.
Reimplemented from vtkTableAlgorithm.
