Method Detail

configure

public void configure(InRange range)

Tells this generator to produce values within a specified minimum and/or maximum, inclusive, with uniform distribution. InRange.min() and InRange.max() take precedence over InRange.minInt() and InRange.maxInt(), if non-empty.

Parameters:

range - annotation that gives the range's constraints
