c++ Using const in a copy constructor?
- by Anton
I have never written copy constructor, so in order to avoid pain i wanted to know if what i have coded is legit. It compiles but i am not sure that it works as a copy constructor should.
Also do i have to use const in the copy constructor or i can simply drop it. (What i dont like about const is that the compiler cries if i use some non const functions).
//EditNode.h
class EditNode
{
explicit EditNode(QString elementName);
EditNode(const EditNode &src);
}
//EditNodeContainer.h
class EditNodeContainer : public EditNode
{
explicit EditNodeContainer(QString elementName);
EditNodeContainer(const EditNodeContainer &src);
}
//EditNodeContainer.cpp
EditNodeContainer::EditNodeContainer(QString elementName):EditNode(elementName)
{
}
//This seems to compile but not sure if it works
EditNodeContainer::EditNodeContainer(const EditNodeContainer &src):EditNode(src)
{
}
//the idea whould be to do something like this
EditNodeContainer *container1 = new EditNodeContainer("c1");
EditNodeContainer *copyContainer = new EditNodeContainer(container1);
