Detailed Description

template<class CONCRETE>
class ACE_Based_Pointer< CONCRETE >

A smart 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 by overloading the C++ delegation operator ->().

ACE_BEGIN_VERSIONED_NAMESPACE_DECL ACE_Based_Pointer< CONCRETE >::ACE_Based_Pointer ( void   ) 

Constructor. See constructor for ACE_Based_Pointer_Basic for details.

template<class CONCRETE>
ACE_Based_Pointer< CONCRETE >::ACE_Based_Pointer ( CONCRETE *  initial  ) 

Initialize this object using the <initial> pointer. See constructor for ACE_Based_Pointer_Basic for details.

template<class CONCRETE>
ACE_Based_Pointer< CONCRETE >::ACE_Based_Pointer ( const void *  base_addr,
int  dummy 
)

Initialize this object with known base_addr. dummy is a dummy value used to resolve overload ambiguity and it otherwise ignored.
