Description:
The purpose of this class is to cache the DOM
Documents in memory and by-pass parsing. For
old systems or laptops, it's not practical to
parse the XML documents every time. Therefore
using a memory cache can reduce the CPU usage
.
For now this is a simple version to test the feasibility of caching. If it works, this class will be replaced with an Apache commons or something equivalent. If I was familiar with Apache Commons Pool, I would probably use it, but since I don't know the API, it is quicker for Proof of Concept to just write a dumb one. If the number documents in the pool exceed several hundred, it will take a long time for the lookup.
