pragma CPP_Class ([Entity =>] LOCAL_NAME);
The argument denotes an entity in the current declarative region that is declared as a tagged or untagged record type. It indicates that the type corresponds to an externally declared C++ class type, and is to be laid out the same way that C++ would lay out the type.
If (and only if) the type is tagged, at least one component in the
record must be of type Interfaces.CPP.Vtable_Ptr
, corresponding
to the C++ Vtable (or Vtables in the case of multiple inheritance) used
for dispatching.
Types for which CPP_Class
is specified do not have assignment or
equality operators defined (such operations can be imported or declared
as subprograms as required). Initialization is allowed only by
constructor functions (see pragma CPP_Constructor
).
Pragma CPP_Class
is intended primarily for automatic generation
using an automatic binding generator tool.
