kandi X-RAY | iterfn Summary

iterfn is a JavaScript library. iterfn has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can install using 'npm i iterfn' or download it from GitHub, npm.

A collection of functions to work with iterators similar to Rust's Iterator trait. Iterators are very useful to work with collections and it's worth knowing that not everything needs to be an array. A very good and detailed explanation of iterators and iterables can be found in Chapter 21. Iterables and iterators of the book Exploring ES6.

Storing references/pointers to Boost MultiSet indexes

QUESTION

Storing references/pointers to Boost MultiSet indexes

Asked 2020-Jun-28 at 13:44

I'm trying to build two classes Collection and CollectionView, which is an abstraction on top of Boost.MultiIndex. The idea is somewhat simple: Give an instance of type Collection to a CollectionView, and it'll handle rendering. The Collection adds an interface for adding or removing items, which in turn will signal to the CollectionView that it needs to do some work.

An excerpt of the classes looks like this:

It sounds like you would really be served by just the random_access_index from Boost Multi Index (BMI).

You can rearrange it in any way you wish. So even if you want to have the user manually rearrange things e.g. they

add an element and it is displayed as the last item regardless of the ordering of the rest of the set
select a custom sort order that doesn't exactly match one of the BMI indices

then you can.

As an aside: note that you can also use BMI containers to merely index non-owned or shared elements. The implementation allows the element type to be T*, T const*, std::reference_wrapper, shared_ptr etc. without any other change to the functionality. Note that it uses generic pointer_traits for this so you can even use std::reference_wrapper > and it would still work.

This is not related to the answer but does resonate with the concept of "external views" as you were contemplating.

See e.g. https://www.boost.org/doc/libs/1_73_0/libs/multi_index/doc/reference/key_extraction.html#chained_pointers

DEMONSTRATION

Let's say we add a random_access index transparently into your container:
