Class MessageContextPredicateAdapter

java.lang.Object

org.opensaml.profile.logic.MessageContextPredicateAdapter

All Implemented Interfaces:

Predicate<MessageContext>

public class MessageContextPredicateAdapter
extends Object
implements Predicate<MessageContext>

A Predicate which adapts an existing ProfileRequestContext predicate for use as a MessageContext predicate.

In normal usage the message context evaluated must have a ProfileRequestContext somewhere in its parent chain. Typically this will be its direct parent context, as supplied by BaseContext.getParent(). An optional flag is supplied to determine the evaluation result when no parent profile request context can be located. This case defaults to false.

One example is for use as a MessageHandler activation condition via AbstractMessageHandler.

Constructor Detail

MessageContextPredicateAdapter

public MessageContextPredicateAdapter(@Nonnull@ParameterName(name="prcPredicate")
                              Predicate<ProfileRequestContext> prcPredicate)

Constructor.

Failure to resolve the ProfileRequestContext parent results in an evaluation of false.

Parameters:

prcPredicate - the adapted predicate

                              boolean unresolvedSatisfies)

Constructor.

Parameters:

prcPredicate - the adapted predicate

unresolvedSatisfies - whether failure to resolve a parent ProfileRequestContext satisfies the predicate
