const bool *	GetIsSetPointer ( const void* Data )
bool *	GetIsSetPointer ( void* Data )
const void *	GetValuePointerForRead ( const void* Data )	For reading the value of a set optional. Must be called on a non-null pointer to a set optional.
const void *	GetValuePointerForReadIfSet ( const void* Data )	For reading the value of a set optional.
void *	GetValuePointerForReadOrReplace ( void* Data )
const void *	GetValuePointerForReadOrReplace ( const void* Data )	For calling from polymorphic code that doesn't know whether it needs the value pointer for read or replace, or whether it has a const pointer or not.
void *	GetValuePointerForReadOrReplaceIfSet ( void* Data )
const void *	GetValuePointerForReadOrReplaceIfSet ( const void* Data )	For calling from polymorphic code that doesn't know whether it needs the value pointer for read or replace, or whether it has a const pointer or not.
void *	GetValuePointerForReplace ( void* Data )	For replacing the value of a set optional. Must be called on a non-null pointer to a set optional.
