Constructor Detail

AbstractHandlerDelegatingProfileAction

public AbstractHandlerDelegatingProfileAction(@Nonnull
                                              Class<DelegateType> delegateClass,
                                              @Nonnull
                                              ContextDataLookupFunction<ProfileRequestContext,MessageContext> lookup)

Constructor.

Parameters:

delegateClass - the delegate class. Must have a no-argument constructor. For those that do not, instead pass in a pre-constructed instance via AbstractHandlerDelegatingProfileAction(DelegateType,org.opensaml.messaging.context.navigate.ContextDataLookupFunction<org.opensaml.profile.context.ProfileRequestContext,org.opensaml.messaging.context.MessageContext>).

lookup - the lookup function for the message context on which to operate, typically for either the inbound or outbound context

AbstractHandlerDelegatingProfileAction

public AbstractHandlerDelegatingProfileAction(@Nonnull
                                              DelegateType delegateInstance,
                                              @Nonnull
                                              ContextDataLookupFunction<ProfileRequestContext,MessageContext> lookup)

Constructor.

Parameters:

delegateInstance - the delegate instance

lookup - the lookup function for the message context on which to operate, typically for either the inbound or outbound context

Method Detail

setErrorEvent

public void setErrorEvent(@Nullable
                          String event)

Set the event to signal in the event of a handler exception.

Parameters:

event - event to signal

doDestroy

protected void doDestroy()

Overrides:

doDestroy in class AbstractInitializableComponent

getDelegate

@Nonnull
protected DelegateType getDelegate()

Get the delegate instance.

Returns:

the delegate instance

adapt

@Nullable
protected Predicate<MessageContext> adapt(@Nullable
                                          Predicate<ProfileRequestContext> predicate)

Adapt a ProfileRequestContext predicate into a MessageContext predicate via composing with a lookup function.

Parameters:

predicate - the profile request context predicate

Returns:

the message context predicate

adapt

@Nullable
protected <T> Function<MessageContext,T> adapt(@Nullable
                                                     Function<ProfileRequestContext,T> function)

Adapt a ProfileRequestContext function to a MessageContext function via composing with a lookup function.

Type Parameters:

T - the output type of the functions

Parameters:

Returns:

the message context function

doExecute

protected void doExecute(@Nonnull
                         ProfileRequestContext profileRequestContext)
