Parameters:

mom - the min/opt/max trait

len - the new minimum length

fixAfterMinChanged

public static void fixAfterMinChanged(MinOptMax mom)

After a calculation on a MinOptMax, this can be called to set opt to a new effective value.

Parameters:

mom - MinOptMax to adjust

toMinOptMax

public static MinOptMax toMinOptMax(LengthRangeProperty prop,
                    PercentBaseContext context)
