Returning *this in member functions

Question

I recently used a library that allows the following type of syntax:

MyClass myObject;
myObject
    .setMember1(\"string value\")
    .setMember2(4.0f)
    .s         


        

Answer 1

There's no problem with this style. The only downside is that you can't use the return value for more typical purposes, like returning the result of the function.
