Method Details

setMetadataContextLookupStrategy

public void setMetadataContextLookupStrategy(@Nonnull
 Function<MessageContext,SAMLMetadataContext> strategy)

Set the strategy to locate the SAMLMetadataContext from the MessageContext.

Parameters:

strategy - lookup strategy

setIndexLookupStrategy

public void setIndexLookupStrategy(@Nullable
 Function<MessageContext,AuthnRequest> strategy)

Set the strategy to locate the AttributeConsumingService index from the MessageContext.

Parameters:

strategy - lookup strategy

doPreInvoke

protected boolean doPreInvoke(@Nonnull
 MessageContext messageContext)
                       throws MessageHandlerException

Called prior to execution, handlers may override this method to perform pre-processing for a request.

The default impl applies the Predicate set via the AbstractMessageHandler.setActivationCondition(Predicate).

If false is returned, execution will not proceed.

Subclasses which override this method should generally invoke the super version of this method first, so that the activation condition will be applied up front, and immediately return false if the super version returns false. This avoids unnecessary execution of the remaining pre-invocation code if the handler ultimately will not execute.

Overrides:

doPreInvoke in class AbstractMessageHandler

Parameters:

messageContext - the message context on which to invoke the handler

Returns:

true iff execution should proceed

Throws:

MessageHandlerException - if there is a problem executing the handler pre-routine

doInvoke

protected void doInvoke(@Nonnull
 MessageContext messageContext)
                 throws MessageHandlerException

Performs the handler logic.

Specified by:

doInvoke in class AbstractMessageHandler

Parameters:

messageContext - the message context on which to invoke the handler

Throws:

MessageHandlerException - if there is an error invoking the handler on the message context

attributeConsumingServiceFromRequestedAttributes

private AttributeConsumingService attributeConsumingServiceFromRequestedAttributes()
                                                                            throws MessageHandlerException

Generate an AttributeConsumingService from the RequestedAttributes.

Returns:

a suitable AttributeConsumingService

Throws:

MessageHandlerException - when the cloning failed

getRequestedAttributes

private List<RequestedAttribute> getRequestedAttributes(AuthnRequest authn)

Grab the RequestedAttribute (if any) from the AuthnRequest.

Parameters:

authn - the request to interrogate

Returns:

null or the list.
