      org.freedesktop.dbus.UInt64

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<UInt64>

public class UInt64
extends java.lang.Number
implements java.lang.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.
