getDifference

public Measurable.Difference getDifference(Measurable beta,
                                           Measurable blackout,
                                           Measurable ignore,
                                           CanonicalFileDescriptor cfd)

Description copied from interface: Measurable

Not optimized version. Usually will just call getDifference (..., null).

Specified by:

getDifference in interface Measurable

Parameters:

beta - the value to subtract/get the difference from

blackout - the bad region

ignore - the ignored region

cfd - the media's information

Returns:

the difference between this and beta, given the constraints

getDifference

public Measurable.Difference getDifference(Measurable beta,
                                           Measurable blackout,
                                           Measurable ignore,
                                           CanonicalFileDescriptor cfd,
                                           Measurable.Difference old)

Description copied from interface: Measurable

For performance reasons, takes an optional (could be null) Measurable.Difference to replace the data from. Calling getDistance (alpha, beta, blackout, ignore) should have the same effect as getDistance (alpha.getDifference (beta, blackout, ignore)) (Except for if alpha is null... then it will use Distances.DefaultDifference

Specified by:

getDifference in interface Measurable

Parameters:

beta - the difference to get against

blackout - the measurable to count as bad

ignore - the measurable region to ignore

cfd - the media file descriptor

old - an old difference to copy into, if possible, like the array passed to list.toArray()

Returns:

the difference between this and beta

validate

public boolean validate(AttributeValue v)

Checks to make sure that the value can be set.

Specified by:

validate in interface AttributeValue

Parameters:

v - the value to validate

Returns:

true iff the value is a valid attribute value for this attribute's type
