Modifier and Type	Method and Description
long	distance(java.math.BigInteger start, java.math.BigInteger 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.math.BigInteger	next(java.math.BigInteger value) Returns the unique least value of type C that is greater than value, or null if none exists.
java.math.BigInteger	previous(java.math.BigInteger value) Returns the unique greatest value of type C that is less than value, or null if none exists.

Method Detail

next

public java.math.BigInteger next(java.math.BigInteger 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.math.BigInteger>

Parameters:

value - any value of type C

Returns:

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

previous

public java.math.BigInteger previous(java.math.BigInteger 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.math.BigInteger>

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.math.BigInteger start,
                     java.math.BigInteger 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.math.BigInteger>

Returns:

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

readResolve

private java.lang.Object readResolve()

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
