Title: Invoking a Base Class Constructor in C++
Post by: Zidane on November 09, 2006, 09:04:37 am

If I manually change a constructor to invoke a constructor of the base class, this info is deleted with the next code generation / synchronisation loop.

Example:

GENERATED HEADER FILES
===================

class A
{
A(int x);
}

class B : private A
{
B(int x);
}

GENERATED CPP FILES
================

A::A(int x){}
B::B(int x){}

================

Now I change last line manually to
---------------------
B::B(int x):A(x){}
---------------------
which would be okay,
but after next synchronization this change is lost.

Any idea?!?

Best regards,
DD.

EA is removing the inialization list because it expects to it to be defined in a tagged value "initializer" on the constructor.  If you add this tagged value then things should work as expected.

For more information on how C++ is modelled in EA please see http://www.sparxsystems.com.au/EAUserGuide/index.html?cpp_conventions.htm
