There are many levels of OOP support, I think that some of them are
really useful:
* Inheritance: I think that static inheritance (ie, no virtual
functions) is really usefull. You could do thinks like
(in C++/Java like syntax)
class myUART : extends picUART {
protected void init() {
baud=9600;
parity=picUART.parity.none;
}
protected void recive(char c) {
// Do something with "c"
}
}
This type of code could be compiled to something very efficient,
including support for different types of UART's depending on the
target chip.
* Polymorphism: This is usefull to write code that can be compiled
with different types. For example, an algorithm can accept 8 bit
integers and 16 bit integers, etc.
Again, I think that in a microcontroller environment, only static
polymorphism is usefull, so the compilar determines which code to
use at compile time, with no runtime overhead.
