Description

Currently, each vector has its own copyFrom method. The implementations for fixed-width vectors are similar, whereas the implementations for the variable-width vectors are similar.

This issue extract such implementations to the base classes, with the following benefits:

1. Less code makes it easier to maintain

2. Move the method to the base class makes the method more convenient to use.
