Detailed Description

A class that manages the current login state.

This is a model class which is typically associated with a single session, for the duration of the session.

Widgets that implement authentication (and thus produce authentication changes), will indicate their result in this object using the login() or logout() methods.

Widgets that want to react to login state changes (typically, as user logging in or out) should listen to the changed() signal of this object.

Constructor & Destructor Documentation

Wt::Auth::Login::Login ( )

Default constructor.

Creates a login object in the LoggedOut state.

Member Function Documentation

Signal& Wt::Auth::Login::changed ( )

Signal that indicates login changes.

This signal is emitted as a result of login() or logout(). If no user was logged in, then a changed() signal does not necessarily mean that user is loggedIn() as the user may have been identified correctly but have a DisabledLogin state() for example.

bool Wt::Auth::Login::loggedIn ( ) const

Returns whether a user has successfully logged in.

This returns true only if the state is WeakLogin or StrongLogin.

See also
state()
void Wt::Auth::Login::login ( const User user,
LoginState  state = StrongLogin 
)

Logs a user in.

A user can be logged in using either a DisabledLogin, WeakLogin or StrongLogin state. The login state is forced to DisabledLogin if User::status() returns Disabled.

See also
logout(), loggedIn()
void Wt::Auth::Login::logout ( )

Logs the current user out.

Sets the state to LoggedOut.

LoginState Wt::Auth::Login::state ( ) const

Returns the current login state.

See also
login(), logout()
const User & Wt::Auth::Login::user ( ) const

Returns the user currently identified.

Returns the user currently identified.

Note
This may also be a user whose account is currently disabled.
