Std Vector Push Back Unique Ptr

I dont want to use stdvector for this because then the extra pointer for the capacity is wasted it will always be the same as the size and i dont have a guarantee that iterators wont be invalided by some resize pushback etc.

Std vector push back unique ptr. 2 stdpmrvector is an alias template that uses a polymorphic allocator the elements are stored contiguously which means that elements can be accessed not only through iterators but also using offsets to regular pointers to elements. I would change the interface to specifically take a uniqueptr that way people know that you are taking ownership of the object. But the real solution is the merge method of stdset in c17. Vector v2 movei1 movei2 movei3.

I have no problem with you storing a vector of pointers or a vector of smart pointer. You are not actually moving directly into the vector v2instead the compiler will create a stdinitializerlist of the moved unique pointers and pass that list object to the stdvector constructor which will then attempt to copy the elements from the initializer list. Stduniqueptr is a smart pointer that owns and manages another object through a pointer and disposes of that object when the uniqueptr goes out of scope. The managing uniqueptr object is assigned another pointer via operator or reset.

Here is my vector code. Void pushbackpointer pointer. In addition to managing the pointed objects lifetime uniqueptr provides the other expected capabilities of a smart pointer. Inserts a new element at the end of the vector right after its current last elementthis new element is constructed in place using args as the arguments for its constructor.

Here is my question. It overloads operator and operator provides a means to obtain the raw pointer get to relinquish control of the pointed object release and to replace the object it manages resetit also lets you customize the way the pointed object is deleted if you dont. This effectively increases the container size by one which causes an automatic reallocation of the allocated storage space if and only if the new vector size surpasses the current vector capacity. Are the following functions going to work to control my vector.

1 stdvector is a sequence container that encapsulates dynamic size arrays. Then the destination set contains a uniqueptr that has the contents that used to be in the one of the source and the source vector now contains an empty uniqueptr. I am new to using smart pointers and have only used uniqueptr so far. The managing uniqueptr object is destroyed.
