interface UInt64Value<T : UInt64Value<T>> : Comparable<T>
(source)
Represents a 64-bit (8 bytes) unsigned integer value.
A UInt64Value is an unsigned integer value whose value can range between 0 and 2^64-1.
This interface defines operations for value types with a 64-bit precision range. The methods provided by this interface take parameters of the same type (and also long
. This provides type safety by ensuring calculations cannot mix different UInt64Value
types.
Where only a pure numerical 64-bit value is required, UInt64 should be used.
It is strongly advised to extend BaseUInt64Value rather than implementing this interface directly. Doing so provides type safety in that quantities of different units cannot be mixed accidentally.

abstract class BaseUInt64Value<T : UInt64Value<T>> : UInt64Value<T>
Base class for UInt64Value. This class is abstract as it is not meant to be used directly, but it has no abstract methods. As mentioned in UInt64Value, this is used to create strongly-typed type aliases of UInt64. In other words, this allow to "tag" numbers with the unit of what they represent for the type-system, which can help clarity, but also forbid mixing numbers that are mean to be of different units (the strongly-typed part). This class implements UInt64Value, but also adds a few operations that take a UInt64 directly, for instance |
|
class UInt64 : UInt64Value<UInt64>
An unsigned 64-bit precision number. This is a raw UInt64Value - a 64-bit precision unsigned number of no particular unit. |
