Description: RefPtr is a smart pointer class template in C++ that can be used to dynamically allocate and manage memory for objects while avoiding memory leaks and dangling references. The startContainer function is a method of the RefPtr class that can be used to obtain a pointer to the start of the managed memory block.
Code Examples:
1. Using RefPtr to manage an array of integers:
```c++
#include
int main() {
RefPtr arr(new int[5]);
arr[0] = 1;
arr[1] = 2;
arr[2] = 3;
arr[3] = 4;
arr[4] = 5;
int* start = arr.startContainer();
// start points to the start of the array
return 0;
}
```
In this example, we allocate an array of integers using RefPtr and initialize its elements. We then use the startContainer method to obtain a pointer to the first element of the array.
Package Library: RefPtr is part of the Poco C++ Libraries, which is a collection of open source C++ libraries that provide functionality for building network- and internet-based applications.
