Class OAuth

java.lang.Object
  de.aitools.aq.websearch.oauth.OAuth

public abstract class OAuth
extends java.lang.Object

The OAuth protocol (http://oauth.net/) is used by some services such as Yahoo and Twitter for authorization purposes. In order to avoid to refer to existing external Java libraries (e.g. Scribe and Signpost), we've implemented the OAuth workflow, again. The current implementation is very basic, because it is primarily written for Yahoo. The implementation bases on Signpost, but uses Java built-in classes instead.
