stack commented on HBASE-11990:
-------------------------------
Use case and patch look good to me. I'd add an example to the javadoc -- the
description on this issue would do -- to the new methods to make it more clear
what the behavior is.
> Make setting the start and stop row for a specific prefix easier

> If you want to set a scan from your application to scan for a specific row
> prefix this is actually quite hard.
> As described in several places you can set the startRow to the prefix; yet
> the stopRow should be set to the prefix '+1'
> If the prefix 'ASCII' put into a byte[] then this is easy because you can
> simply increment the last byte of the array.
> But if your application uses real binary rowids you may run into the scenario
> that your prefix is something like
> {code}{ 0x12, 0x23, 0xFF, 0xFF }{code} Then the increment should be {code}{
> 0x12, 0x24, 0x00, 0x00 }{code}
> I have prepared a proposed patch that makes setting these values correctly a
> lot easier.
