Calling Hidden Members

With Isolator++ Professional you can now call private members.
This is sometimes required in tests - to either test that method, or used to setup a state that is required for the tests.
For this, you'll use the ISOLATOR_INVOKE_ API.

To call a private instance member

ISOLATOR_INVOKE_FUNCTION(retVar,&instance,PrivateMemeber, args...);

In a similar fashion, a static method can be called by passing

ISOLATOR_INVOKE_FUNCTION(retVar,_,MyClass::PrivateMemeber, args...);

Static c functions can be called as follows

ISOLATOR_INVOKE_FUNCTION(retVar,_, staticFunctionInModule, args...);

Note: To catch an exception thrown in an INVOKE PRIVATE method within your test (on a 64-bit system), use the HandleExceptionInTest flag.
