public interface DefinitionResolver
This interface is used to determine the "best match" managed object definition in a definition hierarchy.
Managed object definitions, like Java classes, are arranged in an inheritance hierarchy. When managed objects are decoded (e.g. from LDAP entries), the driver implementation is provided with an "expected managed object definition". However, the actual decoded managed object is often an instance of a sub-type of this definition. For example, when decoding a connection handler managed object, the actual type can never be a connection handler because it is an abstract managed object type. Instead, the decoded managed object must be a "concrete" sub-type: an LDAP connection handler or JMX connection handler.
This resolution process is coordinated by the
resolveManagedObjectDefinition
method in managed
object definitions, where it is passed a
DefinitionResolver
implementation. The
resolveManagedObjectDefinition
method takes care of
recursively descending through the definition hierarchy and invokes
the matches(AbstractManagedObjectDefinition)
method
against each potential sub-type. It is the job of the resolver to
indicate whether the provided managed object definition is a
candidate definition. For example, the LDAP driver provides a
definition resolver which uses the decoded LDAP entry's object
classes to determine the final appropriate managed object
definition.
