Every so often I'll get a compiler error that isn't particularly
clear on what's wrong and eventually I'll figure out that what's
causing it is having a function in an abstract class somewhere
that isn't defined:
abstract class SomeClass {
int someVariable;
void someFunction();
}
the solution is usually:
void someFunction(){}
Usually the abstract class is a converted interface, but it
turned out that I needed to include a variable for it to work out
and I just wasn't keen on remembering to put a mixin in each
derived class.
I'm just wondering why I can't have an undefined function in an
abstract class? I'd the compiler to say, "Hey, you forgot to put
'someFunction()' in 'SomeDerrivedClass', go do something about
that." when I end a function with a semi-colon in the base class
and don't have it in the derrived. Everything just seems to break
in cryptic ways unless I curly brace the function ending.
