/*
This test demonstrates director classes when the types are classes.
Shown are virtual function calls which use classes passed by:
- Value
- Reference
- Pointer
as both parameters and return values.
The test also demonstrates directors used with:
- method overloading
- default parameters
Note: Methods with default parameters that call up from C++ cannot call
the overloaded C# methods, see DefaultParms method.
Expected output if PrintDebug enabled:
------------ Start ------------
Base - Val(444.555)
Base - Ref(444.555)
Base - Ptr(444.555)
Base - FullyOverloaded(int 10)
Base - FullyOverloaded(bool 1)
Base - SemiOverloaded(int -678)
Base - SemiOverloaded(bool 1)
Base - DefaultParms(10, 2.2)
Base - DefaultParms(10, 1.1)
--------------------------------
Derived - Val(444.555)
Derived - Ref(444.555)
Derived - Ptr(444.555)
Derived - FullyOverloaded(int 10)
Derived - FullyOverloaded(bool 1)
Derived - SemiOverloaded(int -678)
Base - SemiOverloaded(bool 1)
Derived - DefaultParms(10, 2.2)
Derived - DefaultParms(10, 1.1)
--------------------------------
CSharpDerived - Val(444.555)
CSharpDerived - Ref(444.555)
CSharpDerived - Ptr(444.555)

CSharpDerived - SemiOverloaded(-678)
