Detailed Description

"Splits" one-or-more table fields by duplicating rows containing delimited data.

Assume the following table:

Author Year Title Brian; Jeff; Tim 2007 Foo Tim 2003 Bar

If we produce a graph relating authors to the year in which they publish, the string "Brian; Jeff; Tim" will be treated (incorrectly) as a single author associated with the year 2007. vtkBoostSplitTableField addresses this by splitting one-or-more fields into "subvalues" using a configurable delimiter and placing each subvalue on its own row (the other fields in the original row are copied). Using the above example, splitting the "Author" field with a ";" (semicolon) delimiter produces:

Author Year Title Brian 2007 Foo Jeff 2007 Foo Tim 2007 Foo Tim 2003 Bar

When this table is converted to a graph, each author (correctly) becomes a separate node.

Usage:

Use AddField() to specify the field(s) to be split. If no fields have been specified, vtkBoostSplitTableField will act as a passthrough. By default, no fields are specified.

The second argument to AddField() is a string containing zero-to-many single character delimiters (multi-character delimiters are not supported).

If the input table is missing a field specified by AddField(), it is an error. If no fields are specified, no splitting is performed. If the delimiter for a field is an empty string, no splitting is performed on that field.

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

static int vtkBoostSplitTableField::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 vtkBoostSplitTableField::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.

void vtkBoostSplitTableField::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.

void vtkBoostSplitTableField::AddField ( const char *  field,
const char *  delimiters 
)
int vtkBoostSplitTableField::RequestData ( vtkInformation request,
vtkInformationVector **  inputVector,
vtkInformationVector outputVector 
) [protected, virtual]

This is called by the superclass. This is the method you should override.
