Access specific glossary fields without triggering first usage

Question

I would like to know if any of the fields that are manually configured during the creation of glossary entries can be accessed manually/deliberately in a macro or newcommand - possibly of the form:

\newcommand{\expectedFirst}[1]{???}

where ??? would be a defintion that would use the gls label, #1, to grab a predefined field such as short, name, label, long, description, firstplural, etc. I would create a new command for each field I wanted to pull, or possibly use

\newcommand{\expectedField}[2]{???}

where #1 would be the label string, and #2 represents the field I want to extract or make accessible.

I poked through the .dtx glossaries file but didn't find any macro definitions that looked like a variable creation that I could duplicate externally. What did look interesting and potentially useful was the presence of a tracking boolean to track whether the term had been called yet or not. This boolean would be another variable I would be interested in comparing with in my custom macros.

MWE:

\documentclass{article}
\usepackage[utf8]{inputenc}

\setlength\parindent{0pt}

Answer 1

Through more careful inspection of the documentation and from inspirations garnered from the comments in the original question, I have found that the glossaries package makes some fields accessible using commands formated similar to \glsentryshort{} and \glsentrylong{}. Most importantly, using these commands doesn't artificially trigger a counter that would prevent the appropriate first use evaluation.

\documentclass{article}
\usepackage[utf8]{inputenc}

\setlength\parindent{0pt}
