The current javadoc for Scan#setStartRow and Scan#setStopRow methods don't accurately capture the semantics of the use of row prefix values. Both methods describe the use of a trailing null byte to change the inclusive/exclusive the respective semantics of setStartRow and setStopRow.
The use of a trailing null byte for start row exclusion only works in the case that exact full matching is done on row keys. The use of a trailing null byte for stop row inclusion has even more limitations (see
The basic example is having the following rows:
Setting the start row to A and the stop row to B will include AAB and AB.
Setting the start row to A\x0 and the stop row to B\x0 will result in the same two rows coming out of the scan, instead of having an effect on the inclusion/exclusion semantics.
