Method Detail

restrict

public static void restrict(MinOptMax mom,
                            LengthRangeProperty lr,
                            PercentBaseContext context)

Restricts a MinOptMax using the values from a LengthRangeProperty.

Parameters:

mom - MinOptMax to restrict

lr - restricting source

context - Percentage evaluation context

extendMinimum

public static void extendMinimum(MinOptMax mom,
                                 int len,
                                 boolean optToLen)

Extend the minimum length to the given length.

Parameters:

mom - the min/opt/max trait

len - the new minimum length

optToLen - if set adjusts the optimum length to be the smaller of the minimum length and the given 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)

Converts a LengthRangeProperty to a MinOptMax.

Parameters:

prop - LengthRangeProperty

context - Percentage evaluation context

Returns:

the requested MinOptMax instance
