You wire up a composition of functions using Google's Functions class and the compose factory-method.

There are two beans already defined that do child lookup of AuthenticationContext and AttributeContext (see utilities.xml):

shibboleth.ChildLookup.AuthenticationContext
shibboleth.ChildLookup.AttributeContext

You wrap those as the two constructor arguments to the compose method.

Totally untested, but I think you could do:

                            <bean class="com.google.common.base.Functions" factory-method="compose"
                                c:g-ref="shibboleth.ChildLookup.AttributeContext"
                                c:f-ref=" shibboleth.ChildLookup.AuthenticationContext" />

The best examples of this wiring are in audit-system.xml.
