Method Detail

obtainHandle

public static DSpaceObject obtainHandle(Map objectModel)
                                 throws SQLException

Obtain the current DSpace handle for the specified request.

Parameters:

objectModel - The cocoon model.

Returns:

A DSpace handle, or null if none found.

Throws:

SQLException

inheritsFrom

public static boolean inheritsFrom(DSpaceObject dso,
                   String parent)
                            throws SQLException

Determine if the given DSO is an ancestor of the the parent handle.

Parameters:

dso - The child DSO object.

parent - The Handle to test against.

Returns:

The matched DSO object or null if none found.

Throws:

SQLException

buildHandleTrail

public static void buildHandleTrail(DSpaceObject dso,
                    PageMeta pageMeta,
                    String contextPath)
                             throws SQLException,
                                    WingException

Build a list of trail metadata starting with the owning collection and ending with the root level parent. If the Object is an item, a bundle, or a bitstream, then the object is not included, but its collection and community parents are. However, if the item is a community or collection then it is included along with all parents.

If the terminal object in the trail is the passed object, do not link to it, because that is (presumably) the page at which the user has arrived.

Parameters:

dso - the DSpace who's parents we wil add to the pageMeta

pageMeta - the object to which we link our trial

contextPath - The context path

Throws:

SQLException

WingException

buildHandleTrail

public static void buildHandleTrail(DSpaceObject dso,
                    PageMeta pageMeta,
                    String contextPath,
                    boolean linkOriginalObject)
                             throws SQLException,
