Method Summary

Modifier and Type	Method and Description
long	distance(java.lang.Long start, java.lang.Long end) Returns a signed value indicating how many nested invocations of DiscreteDomain.next(C) (if positive) or DiscreteDomain.previous(C) (if negative) are needed to reach end starting from start.
java.lang.Long	maxValue() Returns the maximum value of type C, if it has one.
java.lang.Long	minValue() Returns the minimum value of type C, if it has one.
java.lang.Long	next(java.lang.Long value) Returns the unique least value of type C that is greater than value, or null if none exists.
java.lang.Long	previous(java.lang.Long value) Returns the unique greatest value of type C that is less than value, or null if none exists.

Method Detail

next

public java.lang.Long next(java.lang.Long value)

Description copied from class: DiscreteDomain

Returns the unique least value of type C that is greater than value, or null if none exists. Inverse operation to DiscreteDomain.previous(C).

Specified by:

next in class DiscreteDomain<java.lang.Long>

Parameters:

value - any value of type C

Returns:

the least value greater than value, or null if value is maxValue()

previous

public java.lang.Long previous(java.lang.Long value)

Description copied from class: DiscreteDomain

Returns the unique greatest value of type C that is less than value, or null if none exists. Inverse operation to DiscreteDomain.next(C).

Specified by:

previous in class DiscreteDomain<java.lang.Long>

Parameters:

value - any value of type C

Returns:

the greatest value less than value, or null if value is minValue()

distance

public long distance(java.lang.Long start,
                     java.lang.Long end)

Description copied from class: DiscreteDomain

Returns a signed value indicating how many nested invocations of DiscreteDomain.next(C) (if positive) or DiscreteDomain.previous(C) (if negative) are needed to reach end starting from start. For example, if end = next(next(next(start))), then distance(start, end) == 3 and distance(end, start) == -3. As well, distance(a, a) is always zero.

Note that this function is necessarily well-defined for any discrete type.

Specified by:

distance in class DiscreteDomain<java.lang.Long>

Returns:

the distance as described above, or Long.MIN_VALUE or Long.MAX_VALUE if the distance is too small or too large, respectively.

minValue

public java.lang.Long minValue()

Description copied from class: DiscreteDomain

Returns the minimum value of type C, if it has one. The minimum value is the unique value for which Comparable.compareTo(Object) never returns a positive value for any input of type C.

The default implementation throws NoSuchElementException.

Overrides:

minValue in class DiscreteDomain<java.lang.Long>

Returns:

the minimum value of type C; never null

maxValue

public java.lang.Long maxValue()

Description copied from class: DiscreteDomain

Returns the maximum value of type C, if it has one. The maximum value is the unique value for which Comparable.compareTo(Object) never returns a negative value for any input of type C.

The default implementation throws NoSuchElementException.

Overrides:

maxValue in class DiscreteDomain<java.lang.Long>

Returns:

the maximum value of type C; never null

readResolve

private java.lang.Object readResolve()

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
