Method Detail

setEmbargo

void setEmbargo(Context context,
              Item item)
                throws SQLException,
                       AuthorizeException

Put an Item under embargo until the specified lift date. Calls EmbargoSetter plugin to adjust Item access control policies.

Parameters:

context - the DSpace context

item - the item to embargo

Throws:

SQLException

AuthorizeException

getEmbargoTermsAsDate

DCDate getEmbargoTermsAsDate(Context context,
                           Item item)
                             throws SQLException,
                                    AuthorizeException

Get the embargo lift date for an Item, if any. This looks for the metadata field configured to hold embargo terms, and gives it to the EmbargoSetter plugin's method to interpret it into an absolute timestamp. This is intended to be called at the time the Item is installed into the archive.

Note that the plugin is *always* called, in case it gets its cue for the embargo date from sources other than, or in addition to, the specified field.

Parameters:

context - the DSpace context

item - the item to embargo

Returns:

lift date on which the embargo is to be lifted, or null if none

Throws:

SQLException

AuthorizeException

liftEmbargo

void liftEmbargo(Context context,
               Item item)
                 throws SQLException,

                        IOException

Lift the embargo on an item which is assumed to be under embargo. Call the plugin to manage permissions in its own way, then delete the administrative metadata fields that dictated embargo date.

Parameters:

context - the DSpace context

item - the item on which to lift the embargo

Throws:

SQLException

AuthorizeException

IOException
