|

|
|
* @brief merge two columns into a single column
|
||
|
|
*
|
||
|
|
*
|
||
|
|
* vtkMergeColumns replaces two columns in a table with a single column
|
||
|
|
* containing data in both columns. The columns are set using
|
||
|
|
*
|
||
|
|
* SetInputArrayToProcess(0, 0, 0, vtkDataObject::FIELD_ASSOCIATION_ROWS, "col1")
|
||
|
|
*
|
||
|
|
* and
|
||
|
|
*
|
||
|
|
* SetInputArrayToProcess(1, 0, 0, vtkDataObject::FIELD_ASSOCIATION_ROWS, "col2")
|
||
|
|
*
|
||
|
|
* where "col1" and "col2" are the names of the columns to merge.
|
||
|
|
* The user may also specify the name of the merged column.
|
||
|
|
* The arrays must be of the same type.
|
||
|
|
* If the arrays are numeric, the values are summed in the merged column.
|
||
|
|
* If the arrays are strings, the values are concatenated. The strings are
|
||
|
|
* separated by a space if they are both nonempty.
