C++ inserting unique_ptr in map

Question

I have a C++ object of type ObjectArray

typedef map> ObjectArray;

What is the syn

Answer 1

If you want to add an existing pointer to insert into the map, you will have to use std::move.

For example:

std::unique_ptr classPtr(new Class1);

myMap.insert(std::make_pair(0,std::move(classPtr)));
