fuchsia-multiple-inheritance¶
Warns if a class inherits from multiple classes that are not pure virtual.
For example, declaring a class that inherits from multiple concrete classes is disallowed:
class Base_A {
public:
virtual int foo() { return 0; }
};
class Base_B {
public:
virtual int bar() { return 0; }
};
// Warning
class Bad_Child1 : public Base_A, Base_B {};
A class that inherits from a pure virtual is allowed:
class Interface_A {
public:
virtual int foo() = 0;
};
class Interface_B {
public:
virtual int bar() = 0;
};
// No warning
class Good_Child1 : public Interface_A, Interface_B {
virtual int foo() override { return 0; }
virtual int bar() override { return 0; }
};
