Fixed size ring buffer
WebA ring buffer is a buffer with a fixed size. When it fills up, adding another element overwrites the oldest one that was still being kept. It’s particularly useful for the storage of log information and history. There is no direct support in Python for this kind of structure, but it’s easy to construct one. The implementation in this recipe ...

WebI want a simple class that implements a fixed-size circular buffer. It should be efficient, easy on the eyes, generically typed. For now it need not be MT-capable. I can always add a lock later, it won't be high-concurrency in any case. Methods should be: .Add () and I guess .List (), where I retrieve all the entries.
