// Simple class for encapsulating oop pointers stored in metadata.
// These are different from Handle.  The Handle class stores pointers
// to oops on the stack, and manages the allocation from a thread local
// area in the constructor.
// This assumes that the caller will allocate the handle in the appropriate
// area.  The reason for the encapsulation is to help with naming and to allow
// future uses for read barriers.
