i have a RawComparator that i would like to unit test (using mockito and
mrunit testing packages). i want to test the method,
public int compare(byte b1, int s1, int l1, byte b2, int s2, int l2)
how do i convert my custom key into a byte array? is there a util class
to help me do this?
also, when i put the code into the debugger, i notice that the byte
arrays (b1 and b2) are HUGE (the lengths of each array are huge, in the
thousands). what is actually in these byte arrays? intuitively, it does
not seem like these byte arrays only represent my keys.
lastly, why are such huge byte arrays being passed around? one would
think that since Java is pass-by-value, there would be a large overhead
with passing such large byte arrays around.
your help is appreciated.
