AuthProvider
protected AuthProvider(String name,
double version,
String info)
- Constructs a provider with the specified name, version number,
and information.
- Parameters:
name - the provider name.version - the provider version number.info - a description of the provider and its services.
login
public abstract void login(Subject subject,
CallbackHandler handler)
throws LoginException
- Log in to this provider.
The provider relies on a CallbackHandler
to obtain authentication information from the caller
(a PIN, for example). If the caller passes a null
handler to this method, the provider uses the handler set in the
setCallbackHandler method.
If no handler was set in that method, the provider queries the
auth.login.defaultCallbackHandler security property
for the fully qualified class name of a default handler implementation.
If the security property is not set,
the provider is assumed to have alternative means
for obtaining authentication information.
- Parameters:
subject - the Subject which may contain
principals/credentials used for authentication,
or may be populated with additional principals/credentials
after successful authentication has completed.
This parameter may be null.handler - the CallbackHandler used by
this provider to obtain authentication information
from the caller, which may be null
- Throws:
LoginException - if the login operation fails
SecurityException - if the caller does not pass a
security check for
SecurityPermission("authProvider.name"),
where name is the value returned by
this provider's getName method
logout
public abstract void logout()
throws LoginException
- Log out from this provider.
- Throws:
LoginException - if the logout operation fails
SecurityException - if the caller does not pass a
security check for
SecurityPermission("authProvider.name"),
where name is the value returned by
this provider's getName method
setCallbackHandler
public abstract void setCallbackHandler(CallbackHandler handler)
- Set a
CallbackHandler.
The provider uses this handler if one is not passed to the
login method. The provider also uses this handler
if it invokes login on behalf of callers.
In either case if a handler is not set via this method,
the provider queries the
auth.login.defaultCallbackHandler security property
for the fully qualified class name of a default handler implementation.
If the security property is not set,
the provider is assumed to have alternative means
for obtaining authentication information.
- Parameters:
handler - a CallbackHandler for obtaining
authentication information, which may be null
- Throws:
SecurityException - if the caller does not pass a
security check for
SecurityPermission("authProvider.name"),
where name is the value returned by
this provider's getName method
