org.eel.kitchen.jsonschema.uri.DefaultURIDownloader

All Implemented Interfaces:

URIDownloader

public final class DefaultURIDownloader
extends Object
implements URIDownloader

Default URI downloader

URL's API doc guarantees that an implementation can handle the following schemes: http, https, ftp, file and jar.

We choose however not to provide https for certificate handling reasons, which is a pain to get right.
