All Implemented Interfaces:

public class CodeAuthTransitionProvider<A extends AppUser>
extends SimpleTransitionProvider<A,TransitionKey<A>>
implements AnonymousTransitionFactory<TransitionKey<A>,A>, TitleTransitionFactory<TransitionKey<A>,A>, DefaultingTransitionFactory<TransitionKey<A>,A>

TransitionProvider to validate two factor authentication codes. This could be combined with the normal AppUserTransitionProvider but as it works anonymously its safer to keep the logic separate.

Description copied from interface: TransitionFactory

Get target summary to be shown on transition page. In html this content is embedded within a div.block element.

Specified by:

getSummaryContent in interface TransitionFactory<TransitionKey<A extends AppUser>,A extends AppUser>

Parameters:

c - AppContext

cb - ContentBuilder

Returns:

ContentBuilder

getTitle

public java.lang.String getTitle(TransitionKey<A> key,
                                 A target)

public java.lang.String getHeading(TransitionKey<A> key,
                                   A target)

Description copied from interface: TitleTransitionFactory

Get page heading

Specified by:

getHeading in interface TitleTransitionFactory<TransitionKey<A extends AppUser>,A extends AppUser>

Returns:

String heading

getDefaultTransition

public TransitionKey<A> getDefaultTransition(A target)

Description copied from interface: DefaultingTransitionFactory

Get the key for the default transition. This method can return null if a sub-class wants to suppress the default transition, if there is no valid default for the target or if a view transition is to be used. Note that the target msut be non-null. To implement a default transition with no target use IndexTransitionFactory

Specified by:

getDefaultTransition in interface DefaultingTransitionFactory<TransitionKey<A extends AppUser>,A extends AppUser>

Returns:

transition key
