instead.@Service(value=Importer.class) @Properties(value=@Property(name="service.description",value="Abstract HTTP based Importer")) @Deprecated public abstract class HttpImporter extends java.lang.Object implements Importer
HttpImporter
is an abstract implementation of the
Importer
service interface supporting access to data using the HTTP
protocol.
Extensions of this base class must implement the
importData(String, InputStream, String, Resource)
method to actuall
import the retrieved data.
Instanes of this base class must be initialized before being used and
be destroyed when not used any more. If the extesion is registered as an
Declarative Services Component, this initialization and destroyal is being
taken care of. Otherwise, the extension class must explicitly call the
init()
and destroy()
methods respectively.
The activate(ComponentContext)
and
deactivate(ComponentContext)
methods may be overwritten by extension
classes but the base class implementation must called in this case to
ensure proper initialization and destroyal.
