Class SAMLMetadataLookupHandler

  • All Implemented Interfaces:
    net.shibboleth.utilities.java.support.component.Component, net.shibboleth.utilities.java.support.component.DestructableComponent, net.shibboleth.utilities.java.support.component.InitializableComponent, org.opensaml.messaging.handler.MessageHandler
    public class SAMLMetadataLookupHandler
extends org.opensaml.messaging.handler.AbstractMessageHandler
    Handler for inbound SAML protocol messages that attempts to locate SAML metadata for a SAML entity, and attaches it as a SAMLMetadataContext child of a pre-existing concrete instance of AbstractSAMLEntityContext.

    The entity context class is configurable and defaults to SAMLPeerEntityContext. The handler will no-op in the absence of an existing AbstractSAMLEntityContext child of the message context with non-null values for both entityID and role.

    If the optional copy strategy is configured via setCopyContextStrategy(Function), and if that lookup finds an existing metadata context with compatible data (matching entityID and role), then its data will be re-used.

    Otherwise an attempt to resolve metadata will be performed with the configured RoleDescriptorResolver. A protocol from a SAMLProtocolContext will be added to the lookup, if available.

        Attempt to resolve an existing SAMLMetadataContext from which to copy.

        The returned context will always be a fresh parent-less instance, suitable for the caller to directly store in the current message context.

        messageContext - the current message context
        entityID - the entityID against which to match
        role - the entity role against which to match
        Returns:
        a new instance of SAMLMetadataContext, or null if one can not be resolved
