Class BaseOAuthClient<U extends OAuth20Profile>

java.lang.Object

org.pac4j.core.util.InitializableObject

org.pac4j.core.client.BaseClient<OAuthCredentials,U>

org.pac4j.oauth.client.BaseOAuthClient<U>

All Implemented Interfaces:

Cloneable, Client<OAuthCredentials,U>

Direct Known Subclasses:

BaseOAuth10Client, BaseOAuth20Client

public abstract class BaseOAuthClient<U extends OAuth20Profile>
extends BaseClient<OAuthCredentials,U>

This class is a base implementation for an OAuth protocol client based on the Scribe library. It should work for all OAuth clients. In subclasses, some methods are to be implemented / customized for specific needs depending on the client.
