A proxy that keeps track of the relative offset of a "pointer" from its base address. This class makes it possible to transparently use "pointers" in shared memory as easily as programming with pointers to local memory. In particular, we don't need to ensure that the base addresses of all the pointers are mapped into separate processes at the same absolute memory base address. More...

ACE_Based_Pointer_Basic< CONCRETE >::ACE_Based_Pointer_Basic | ( | void | ) |
This constructor initializes the <base_offset_> by asking the <ACE_BASED_POINTER_REPOSITORY> Singleton for the base address of the memory region within which it is instantiated. Two results are possible:
ACE_Based_Pointer_Basic< CONCRETE >::ACE_Based_Pointer_Basic | ( | CONCRETE * | initial | ) |
Initialize this object using the initial pointer. This constructor initializes the <base_offset_> by asking the <ACE_BASED_POINTER_REPOSITORY> Singleton for the base address of the memory region within which it is instantiated. Three results are possible:
ACE_Based_Pointer_Basic< CONCRETE >::ACE_Based_Pointer_Basic | ( | const ACE_Based_Pointer_Basic< CONCRETE > & | ) |
Copy constructor.
ACE_Based_Pointer_Basic< CONCRETE >::ACE_Based_Pointer_Basic | ( | const void * | base_addr, |
int | o | ||
) |
Constructor for know base address. o is only used to resolve overload ambiguity.
