Method Detail

configure

public void configure(InRange range)

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

Parameters:

range - annotation that gives the range's constraints
