/**
|
* This interface is used to determine the "best match" managed object
|
* definition in a definition hierarchy.
|
* <p>
|
* 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.
|
* <p>
|
* This resolution process is coordinated by the
|
* <code>resolveManagedObjectDefinition</code> method in managed
|
* object definitions, where it is passed a
|
* <code>DefinitionResolver</code> implementation. The
|
* <code>resolveManagedObjectDefinition</code> method takes care of
|
* recursively descending through the definition hierarchy and invokes
|
* the {@link #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.
