Hi All,
In C++ we could pass a constant reference to a function so that the
target function could not modify the objects passed
eg. const classA & dummmyfunction(const classB)
similar thing was valid for objects passed with pointer to constant
objects
In C++/CLI is there any way for imitating this, I want to pass
arguments to and return value from my member function as a constant
objects.
Sadly no, the compiler throws an error as soon as you try to declare const
member functions, so passing handles to const is pretty useless: you can't
even read properties.
currently i am passing a handle to the object to client (consumer)
function which then can easily modify the object received
I had one more doubt about C++/CLI
In C++/CLI Handles are similar(may be not not equivalent) to that for C
++ pointers
Is there any operator that is equivalent to C++ References (&) in C++/
CLI
The tracking reference (%) is the version of the C++ reference that supports
garbage collection
any help will be appreciated
Thanks and Regards,
Subodh
