Error message

Not yet implemented

What it means

Builder.sort(String) is a stub in this library: calling it always throws UnsupportedOperationException("Not yet implemented"). It fires unconditionally whenever a caller attempts to sort the builder's rows by a column; no input is at fault.

Solutions

1. Avoid calling sort(column) on DataHolder.Builder
2. Implement sorting by comparing row values with standard data-type comparators
3. Sort the data before inserting it into the builder
