Class XMLCacheResolverExtension

java.lang.Object

org.eclipse.lemminx.extensions.contentmodel.uriresolver.XMLCacheResolverExtension

All Implemented Interfaces:

org.apache.xerces.xni.parser.XMLEntityResolver, URIResolverExtension

public class XMLCacheResolverExtension
extends Object
implements URIResolverExtension

URI resolver which, on the first access, downloads the XML Schema or DTD from "http(s)" or "ftp" URIs to the file system. On subsequent calls, the locally cached file is used instead of being remotely accessed. This cache drastically improves the resolution performance of some XML Schemas (ex: xml.xsd)
