-------------------------------
Summary: Extract the logic for vector data copying to the super
classes
Key: ARROW-5778
URL: https://issues.apache.org/jira/browse/ARROW-5778
Project: Apache Arrow
Issue Type: Improvement
Components: Java
Reporter: Liya Fan
Assignee: Liya Fan
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.
