Class AttributeConsumingServiceSelector

java.lang.Object

org.opensaml.saml.metadata.support.AttributeConsumingServiceSelector

public class AttributeConsumingServiceSelector
extends Object

Metadata support class which selects an AttributeConsumingService based on input of a mandatory RoleDescriptor and an optional index.

This implementation supports selecting an AttributeConsumingService from parent role descriptors of the following types:

1. the standard SAML 2 metadata type SPSSODescriptor
2. the extension type AttributeQueryDescriptorType

Subclasses should override getCandidates() if support for additional sources of attribute consuming services is needed.

The selection algorithm is:

1. If an index is supplied, the service with that index is returned. If no such service exists in metadata: if isOnBadIndexUseDefault() is true, then the default service is returned as described below; otherwise null is returned.
2. If an index is not supplied, then the default service is returned as follows: The service with an explicit isDefault of true is returned. If no such service exists, then the first service without an explicit isDefault is returned. If no service is yet selected, then the first service listed in metadata is returned.
