vtkTokenValueFilter Class Reference

#include <vtkTokenValueFilter.h>

Detailed Description

Filters tokens based on their value.

vtkTokenValueFilter removes tokens from the pipeline based on whether they match a list of token values. Typically, this is useful for handling lists of "stop words" that should be removed from the token stream before further analysis.

Inputs: Input port 0: (required) A vtkTable containing a column of text.

Outputs: Output port 0: The same table, with (potentally) fewer rows.

Use SetInputArrayToProcess(0, ...) to specify the "text" array.

Use AddValue() to append a new token value to the list of values to be discarded. By default, the list of values to be discarded is empty, so you must call AddValue() before using vtkTokenValueFilter to see any changes in output!
