Method Detail

create

Bundle create(Context context,
              Item item,
              String name)
       throws SQLException,
              AuthorizeException

Create a new bundle, with a new ID and link it to the provided item

Parameters:

context - DSpace context object

item - DSpace item

name - bundle name

Returns:

the newly created bundle

Throws:

AuthorizeException - if authorization error

SQLException - if database error

getBitstreamByName

Bitstream getBitstreamByName(Bundle bundle,
                             String name)

addBitstream

void addBitstream(Context context,
                  Bundle bundle,
                  Bitstream bitstream)
           throws SQLException,
                  AuthorizeException

Add an existing bitstream to this bundle

Parameters:

context - DSpace Context

bundle - the bitstream bundle

bitstream - the bitstream to add

Throws:

AuthorizeException - if authorization error

SQLException - if database error

removeBitstream

void removeBitstream(Context context,
                     Bundle bundle,
                     Bitstream bitstream)
              throws AuthorizeException,
                     SQLException,
                     IOException

Remove a bitstream from this bundle - the bitstream is only deleted if this was the last reference to it

If the bitstream in question is the primary bitstream recorded for the bundle the primary bitstream field is unset in order to free the bitstream from the foreign key constraint so that the cleanup process can run normally.

Parameters:

context - DSpace Context

bundle - the bitstream bundle

bitstream - the bitstream to remove

Throws:

IOException - if IO error

AuthorizeException - if authorization error

SQLException - if database error

inheritCollectionDefaultPolicies

void inheritCollectionDefaultPolicies(Context context,
                                      Bundle bundle,
                                      Collection collection)
                               throws SQLException,
                                      AuthorizeException

remove all policies on the bundle and its contents, and replace them with the DEFAULT_BITSTREAM_READ policies belonging to the collection.

Parameters:

context - DSpace Context

bundle - the bitstream bundle

collection - Collection

Throws:

SQLException - if an SQL error or if no default policies found. It's a bit draconian, but default policies must be enforced.

AuthorizeException - if authorization error

replaceAllBitstreamPolicies

void replaceAllBitstreamPolicies(Context context,
                                 Bundle bundle,
                                 List<ResourcePolicy> newpolicies)
                          throws SQLException,
                                 AuthorizeException

remove all of the policies for the bundle and bitstream contents and replace them with a new list of policies

Parameters:

context - DSpace Context

bundle - the bitstream bundle

newpolicies - - this will be all of the new policies for the bundle and bitstream contents

Throws:

SQLException - if database error

AuthorizeException - if authorization error

getBitstreamPolicies
