dereferenceAbsoluteURI

public static org.dspace.content.Bitstream dereferenceAbsoluteURI(org.dspace.core.Context context,
                                                  URI uri)
                                                           throws SQLException

Returns the Bitstream object containing the file in the asset store indicated by the URI, or null if there is none. See getAbsoluteURI().

Parameters:

context - - the context.

uri - a bitstream absolute URI created by getAbsoluteURI()

Returns:

a Bitstream object or null.

Throws:

SQLException

getAbsoluteURI

public URI getAbsoluteURI(org.dspace.core.Context context,
                 org.dspace.content.Bitstream bitstream)

Returns a URI of the storage occupied by this bitstream in the asset store. It can be resolved by the dereferenceAbsoluteURI() method. Note that the "absolute" URI does not depend on the DSpace object model or RDBMS storage, it only depends on the asset store layer.

Returns:

external-based URI to bitstream.
