Class DOMPool


  • public final class DOMPool
    extends Object
    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.
