Multiline

What it does

This class handles multiline text attribute data for EAV entities in Magento 2.

Developers use it to validate, extract, and format multiline input fields (like street addresses) ensuring they don't exceed the maximum allowed lines and meet validation requirements.

It converts between array and string representations, storing data as newline-separated text.
