Class UInt64

java.lang.Object

java.lang.Number

org.freedesktop.dbus.UInt64

All Implemented Interfaces:

Serializable, Comparable<UInt64>

public class UInt64
extends Number
implements Comparable<UInt64>

Class to represent unsigned 64-bit numbers. Warning: Any functions which take or return a long are restricted to the range of a signed 64bit number. Use the BigInteger methods if you wish access to the full range.

public UInt64(long _top,
              long _bottom)

Create a UInt64 from two longs.

Parameters:

_top - Most significant 4 bytes.

_bottom - Least significant 4 bytes.

UInt64

public UInt64(BigInteger _value)

Create a UInt64 from a BigInteger

Parameters:

_value - Must be a valid BigInteger between MIN_VALUE–MAX_BIG_VALUE

Throws:

UInt64

public UInt64(String _value)

Create a UInt64 from a String.

Parameters:

_value - Must parse to a valid integer within MIN_VALUE–MAX_BIG_VALUE

Throws:

NumberFormatException - if value is not an integer between MIN_VALUE and MAX_BIG_VALUE
