// .NAME vtkBoostSplitTableField - "Splits" one-or-more table fields by duplicating rows containing delimited data.
|
|
// .SECTION Description
|
|
//
|
|
// 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.
