All Implemented Interfaces:

URIResolver

public class S3URIResolver
extends Object
implements URIResolver

URI Resolver that will be used by XLTProcessor when resolving xsl:import and xsl:include statements. The purpose of this class is to create a local cache of the stylesheets retrieved (presumably) from S3 so they don't need to be re-retrieved from S3 on subsequent requests.
