Class DefaultDisseminatorImpl

java.lang.Object
  fedora.server.access.defaultdisseminator.InternalService
      fedora.server.access.defaultdisseminator.DefaultDisseminatorImpl

All Implemented Interfaces:

DefaultDisseminator

public class DefaultDisseminatorImpl
extends InternalService
implements DefaultDisseminator

Title: DefaultDisseminatorImpl.java

Description: Implements the methods defined in the DefaultDisseminator interface. This is the default behavior mechanism that implements the "contract" of the default behavior definition that is dynamically associated with every digital object in the repository. This class is considered an "internal service" that is built in to the Fedora system. Its purpose is to endow every digital object with a set of generic behaviors. It is an implementation of what is known as the Default Disseminator. Unlike other behavior definitions and mechanisms, there is no Behavior Definition Object or Behavior Mechanism Object stored in the repository.

Method Detail

viewObjectProfile

public MIMETypedStream viewObjectProfile()
                                  throws ServerException

Returns an HTML rendering of the object profile which contains key metadata from the object, plus URLs for the object's Dissemination Index and Item Index. The data is returned as HTML in a presentation-oriented format. This is accomplished by doing an XSLT transform on the XML that is obtained from getObjectProfile in API-A.

Specified by:

viewObjectProfile in interface DefaultDisseminator

Returns:

html packaged as a MIMETypedStream

Throws:

ServerException

viewMethodIndex

public MIMETypedStream viewMethodIndex()
                                throws ServerException

Returns an HTML rendering of the Dissemination Index for the object. The Dissemination Index is a list of method definitions that represent all disseminations possible on the object. The Dissemination Index is returned as HTML in a presentation-oriented format. This is accomplished by doing an XSLT transform on the XML that is obtained from listMethods in API-A.

Specified by:

viewMethodIndex in interface DefaultDisseminator

Returns:

html packaged as a MIMETypedStream

Throws:

ServerException

viewItemIndex

public MIMETypedStream viewItemIndex()
                              throws ServerException

Returns an HTML rendering of the Item Index for the object. The Item Index is a list of all datastreams in the object. The datastream items can be data or metadata. The Item Index is returned as HTML in a presentation-oriented format. This is accomplished by doing an XSLT transform on the XML that is obtained from listDatastreams in API-A.

Specified by:

viewItemIndex in interface DefaultDisseminator

Returns:

html packaged as a MIMETypedStream

Throws:

ServerException

viewDublinCore

public MIMETypedStream viewDublinCore()
                               throws ServerException

Returns the Dublin Core record for the object, if one exists. The record is returned as HTML in a presentation-oriented format.

Specified by:

viewDublinCore in interface DefaultDisseminator

Returns:

html packaged as a MIMETypedStream

Throws:

ServerException

reflectMethods

public static MethodDef[] reflectMethods()

Method implementation of reflectMethods from the InternalService interface. This will return an array of method definitions that constitute the behaviors of the Default Disseminator which is associated with every Fedora object. These will be the methods promulgated by the DefaultDisseminator interface.

Returns:

an array of method defintions
