- NS_IMPL_[CLASS_]GETSET[_<type>]([class, ]postfix, [type,] member);
-
- where:
- CLASS_ - implementation is inside a class definition
- (otherwise the class name is needed)
- Do NOT use in publicly exported header files, because
- the implementation may be included many times over.
- Instead, use the non-CLASS_ version.
- _<type> - For more complex (STR, IFACE) data types
- (otherwise the simple data type is needed)
- method - name of the method, such as GetWidth or SetColor
- type - simple data type if required
- member - class member variable such as m_width or mColor
- class - the class name, such as Window or MyObject
- postfix - Method part after Get/Set such as "Width" for "GetWidth"
-
- Example:
- class Window {
- public:
- NS_IMPL_CLASS_GETSET(Width, int, m_width);
- NS_IMPL_CLASS_GETTER_STR(GetColor, m_color);
- NS_IMETHOD SetColor(char *color);
-
- private:
- int m_width; // read/write
- char *m_color; // readonly
- };
-
- // defined outside of class
- NS_IMPL_SETTER_STR(Window::GetColor, m_color);
