Class NodeEntityResolver

java.lang.Object

uk.ac.starlink.datanode.nodes.NodeEntityResolver

All Implemented Interfaces:

EntityResolver

public class NodeEntityResolver
extends Object
implements EntityResolver

Provides specialised XML entity resolution for data nodes. As well as the local copies of some useful entities provided by the superclass StarEntityResolver any entity which is retrieved using a URL by this entity resolver is cached for future use for the case in which, for instance, multiple files in the same directory reference the same external entity. Done this way, you don't have to keep making network connections, you keep a copy of the items you retrieve. Obviously, there is a down side, you can fill up memory with things that you're not going to need again. Try it like this for now.
