+/**
+ * The configuration information for a <code>ManagedService</code> or
+ * <code>ManagedServiceFactory</code> object.
+ *
+ * The Configuration Admin service uses this interface to represent the
+ * configuration information for a <code>ManagedService</code> or for a
+ * service instance of a <code>ManagedServiceFactory</code>.
+ *
+ * <p>
+ * A <code>Configuration</code> object contains a configuration dictionary and
+ * allows the properties to be updated via this object. Bundles wishing to
+ * receive configuration dictionaries do not need to use this class - they
+ * register a <code>ManagedService</code> or
+ * <code>ManagedServiceFactory</code>. Only administrative bundles, and
+ * bundles wishing to update their own configurations need to use this class.
+ *
+ * <p>
+ * The properties handled in this configuration have case insensitive
+ * <code>String</code> objects as keys. However, case is preserved from the
+ * last set key/value.
+ * <p>
+ * A configuration can be <i>bound </i> to a bundle location (
+ * <code>Bundle.getLocation()</code>). The purpose of binding a
+ * <code>Configuration</code> object to a location is to make it impossible
+ * for another bundle to forge a PID that would match this configuration. When a
+ * configuration is bound to a specific location, and a bundle with a different
+ * location registers a corresponding <code>ManagedService</code> object or
+ * <code>ManagedServiceFactory</code> object, then the configuration is not
+ * passed to the updated method of that object.
+ *
+ * <p>
+ * If a configuration's location is <code>null</code>, it is not yet bound to
+ * a location. It will become bound to the location of the first bundle that
+ * registers a <code>ManagedService</code> or
+ * <code>ManagedServiceFactory</code> object with the corresponding PID.
+ * <p>
+ * The same <code>Configuration</code> object is used for configuring both a
+ * Managed Service Factory and a Managed Service. When it is important to
+ * differentiate between these two the term "factory configuration" is used.

+/**
+ * Service for administering configuration data.
+ *
+ * <p>
+ * The main purpose of this interface is to store bundle configuration data
+ * persistently. This information is represented in <code>Configuration</code>
+ * objects. The actual configuration data is a <code>Dictionary</code> of
+ * properties inside a <code>Configuration</code> object.
+ *
+ * <p>
+ * There are two principally different ways to manage configurations. First
+ * there is the concept of a Managed Service, where configuration data is
+ * uniquely associated with an object registered with the service registry.
+ *
+ * <p>
+ * Next, there is the concept of a factory where the Configuration Admin service
+ * will maintain 0 or more <code>Configuration</code> objects for a Managed
+ * Service Factory that is registered with the Framework.
+ *
+ * <p>
+ * The first concept is intended for configuration data about "things/services"
+ * whose existence is defined externally, e.g. a specific printer. Factories are
+ * intended for "things/services" that can be created any number of times, e.g.
+ * a configuration for a DHCP server for different networks.
+ *
+ * <p>
+ * Bundles that require configuration should register a Managed Service or a
+ * Managed Service Factory in the service registry. A registration property
+ * named <code>service.pid</code> (persistent identifier or PID) must be used to
+ * identify this Managed Service or Managed Service Factory to the Configuration
+ * Admin service.
+ *
+ * <p>
+ * When the ConfigurationAdmin detects the registration of a Managed Service, it
+ * checks its persistent storage for a configuration object whose
+ * <code>service.pid</code> property matches the PID service property (
+ * <code>service.pid</code>) of the Managed Service. If found, it calls
+ * {@link ManagedService#updated} method with the new properties. The
+ * implementation of a Configuration Admin service must run these call-backs
+ * asynchronously to allow proper synchronization.
+ *
+ * <p>
+ * When the Configuration Admin service detects a Managed Service Factory
+ * registration, it checks its storage for configuration objects whose
+ * <code>service.factoryPid</code> property matches the PID service property of
+ * the Managed Service Factory. For each such <code>Configuration</code>
+ * objects, it calls the <code>ManagedServiceFactory.updated</code> method
+ * asynchronously with the new properties. The calls to the <code>updated</code>
+ * method of a <code>ManagedServiceFactory</code> must be executed sequentially
+ * and not overlap in time.
+ *
+ * <p>
+ * In general, bundles having permission to use the Configuration Admin service
+ * can only access and modify their own configuration information. Accessing or
+ * modifying the configuration of another bundle requires
+ * <code>ConfigurationPermission[*,CONFIGURE]</code>.
+ *
+ * <p>
+ * <code>Configuration</code> objects can be <i>bound </i> to a specified bundle
+ * location. In this case, if a matching Managed Service or Managed Service
+ * Factory is registered by a bundle with a different location, then the
+ * Configuration Admin service must not do the normal callback, and it should
+ * log an error. In the case where a <code>Configuration</code> object is not
+ * bound, its location field is <code>null</code>, the Configuration Admin
+ * service will bind it to the location of the bundle that registers the first
+ * Managed Service or Managed Service Factory that has a corresponding PID
+ * property. When a <code>Configuration</code> object is bound to a bundle
+ * location in this manner, the Configuration Admin service must detect if the
+ * bundle corresponding to the location is uninstalled. If this occurs, the
+ * <code>Configuration</code> object is unbound, that is its location field is
+ * set back to <code>null</code>.
+ *
+ * <p>
+ * The method descriptions of this class refer to a concept of "the calling
+ * bundle". This is a loose way of referring to the bundle which obtained the
+ * Configuration Admin service from the service registry. Implementations of
+ * <code>ConfigurationAdmin</code> must use a
+ * {@link org.osgi.framework.ServiceFactory} to support this concept.

+ *
+ * <p>
+ * Configuration Plugin (plugin) services have full read/write access to all
+ * configuration information. Therefore, bundles using this facility should be
