This chapter summarizes the rationale for operator overloading and provides examples and explanations for overloading the various categories of operators. The concept of operators in C++ is broad, and even incl
To understand the need for operator overloading, imagine that you need to perform matrix math operations in your program. You could instantiate a couple 2-dimensional arrays and do what you need. However, add the requirement for the matrix behavior to be reusable. Because you need to do the...
The bitshift operators<<and>>, although still used in hardware interfacing for the bit-manipulation functions they inherit from C, have become more prevalent as overloaded stream input and output operators in most applications. For guidance overloading as bit-manipulation operators, see the section ...

Operators overloading in AS3 (JavaScript too) – Workaround It’s possible to overload operators in AS3, e.g: [1, 2, 3] + [“a”, “b”] will result in [1, 2, 3, “a”, “b”]. You can try it yourself in Fingers, where such a constructions are possible: 1 on(sprite...
Static operator overloading is one of my main complaints about the language. The problem was not apparent to me until generics were introduced. Try to overload the operators in a generic type. You can not use generic constraints since overloaded operators are static and the compiler will ...
