Address (Jikes RVM API)

java.lang.Object
- org.vmmagic.unboxed.Address

```
public final class Address
extends Object
```
Stub implementation of an Address type, intended only to allow the core of MMTk to be compiled. This must be replaced with a concrete implementation appropriate to a specific VM.
The address type is used by the runtime system and collector to denote machine addresses. We use a separate type instead of the Java int type for coding clarity, machine-portability (it can map to 32 bit and 64 bit integral types), and access to unsigned operations (Java does not have unsigned int types).
