An instance of this union is a raw block of memory suitable for storing an object of type TYPE. Specifically, the size and alignment of this union exactly matches that of TYPE. A TYPE object can be constructed into an ObjectBuffer using the placement new operator and can be destroyed by explicitly calling its destructor, ~TYPE(). It is the user's responsibility to perform this construction and destruction; an ObjectBuffer object does not manage the construction or destruction of any other objects.
Note that a collaboration is implied between ObjectBuffer and the user. An ObjectBuffer provides aligned memory and the user handles construction and destruction of the object contained within that memory.

| TYPE* bsls::ObjectBuffer< TYPE >::address | ( | ) |
Return the address of the first byte of this object, cast to a TYPE * pointer.
Referenced by bslalg::NothrowMovableWrapper< TYPE >::NothrowMovableWrapper().
| char* bsls::ObjectBuffer< TYPE >::buffer | ( | ) |
Return the address of the first byte of this object, cast to a char * pointer.
| TYPE& bsls::ObjectBuffer< TYPE >::object | ( | ) |
Return a modifiable reference to the TYPE object occupying this buffer. The referenced object has undefined state unless a valid TYPE object has been constructed in this buffer.
Referenced by bslalg::NothrowMovableWrapper< TYPE >::get_allocator(), bslalg::NothrowMovableWrapper< TYPE >::unwrap(), and bslalg::NothrowMovableWrapper< TYPE >::~NothrowMovableWrapper().
| const TYPE* bsls::ObjectBuffer< TYPE >::address | ( | ) | const |
Return the address of the first byte of this object, cast to a const TYPE * pointer.
| const char* bsls::ObjectBuffer< TYPE >::buffer | ( | ) | const |
Return the address of the first byte of this object, cast to a const char * pointer.
| const TYPE& bsls::ObjectBuffer< TYPE >::object | ( | ) | const |
Return a const reference to the TYPE object occupying this buffer. The referenced object has undefined state unless a valid TYPE object has been constructed in this buffer.
