pragma CPP_Vtable ( [Entity =>] ENTITY, [Vtable_Ptr =>] vtable_ENTITY, [Entry_Count =>] static_integer_EXPRESSION);
Given a record to which the pragma CPP_Class
applies,
this pragma can be specified for each component of type
CPP.Interfaces.Vtable_Ptr
.
Entity is the tagged type, Vtable_Ptr
is the record field of type Vtable_Ptr
, and Entry_Count is
the number of virtual functions on the C++ side. Not all of these
functions need to be imported on the Ada side.
You may omit the CPP_Vtable
pragma if there is only one
Vtable_Ptr
component in the record and all virtual functions are
imported on the Ada side (the default value for the entry count in this
case is simply the total number of virtual functions).
Pragma CPP_Vtable
is intended primarily for automatic generation
using an automatic binding generator tool.
