User Comments


METHODS

User Comments


Constructor Methods

User Comments


create

$eprint = EPrints::DataObj::EPrint->create( $session, $dataset, $data )

Create a new EPrint entry in the given $dataset..

If $data is defined, then this is used as the base for the new record. Otherwise the repository specific defaults provided by

set_eprint_defaults are used.

The fields eprintid and dir will be overridden even if they are set.

User Comments


create_from_data

$dataobj = EPrints::DataObj::EPrint->create_from_data( $session, $data, $dataset ) 

Create a new object of this type in the database.

$dataset is the dataset it will belong to.

$data is the data structured as with EPrints::DataObj#new_from_data.

This will also create sub-objects also.

User Comments


Class Methods

User Comments


get_system_field_info

$fields = EPrints::DataObj::EPrint->get_system_field_info

Return an array describing the system metadata of the eprint dataset.

User Comments


get_dataset_id

$dataset = EPrints::DataObj::EPrint->get_dataset_id

Returns the ID of the EPrints::DataSet object to which this record belongs.

User Comments


get_defaults

$defaults = EPrints::DataObj::EPrint->get_defaults( $class, $session, $data, $dataset )

Returns default values for this data object based on the starting $data.

User Comments


Object Methods

User Comments


set_item_issues

$eprint->set_item_issues( $new_issues )

This method updates the issues associated to this eprint based on the $new_issues passed.

If an existing issue is set as discovered and doesn't exist in $new_issues its status will be updated to autoresolved, otherwise the old issue's status and description are updated.

Any issues in $new_issues that don't already exist will be appended.

User Comments


fileinfo

$fileinfo = $eprint->fileinfo

The special fileinfo field contains the icon and main file paths and filenames for each non-volatile document in the eprint. This is a performance tweak to avoid having to retrieve documents when rendering eprint citations.

Example:

/style/images/fileicons/application_pdf.png;/20/1/paper.pdf|/20/4.hassmallThumbnailVersion/tdb_portrait.jpg;/20/4/tdb_portrait.jpg
 

User Comments


update_triggers

$eprint->update_triggers

Update all the stuff that needs updating before an eprint data object is written to the database.

User Comments


get_dataset

$dataset = $eprint->get_dataset

Returns the dataset to which this object belongs. This will return one of the virtual datasets, by default: inbox, buffer, archive or deletion.

User Comments


store_path

$path = $eprint->store_path

Get the storage path for this eprint data object.

User Comments


clone

$eprint = $eprint->clone( $dest_dataset, $copy_documents, $link )

Create a copy of this eprint data object with a new ID in the given $dest_dataset.

Returns the new eprint, or undef in the case of an error.

If $copy_documents is set and true then the documents (and files) will be copied in addition to the metadata.

If $nolink is true then the new eprint is not connected to the old one by not setting the new eprint's succeeds field.

User Comments


log_mail_owner

$eprint->log_mail_owner( $mail )

Log that the given $mail message was sent to the owner of this eprint data object.

$mail is the same XHTML DOM that was sent as the email.

User Comments


get_editorial_contact

$user = $eprint->get_editorial_contact

Returns the user identified as the editorial contact for this item.

By default returns undef.

N.B. This does no relate to any editors defined in the metadata for this eprint data object.

User Comments


empty

$eprint->empty( [ $clear_all ] )

Remove all documents and set to empty (almost) all fields.

If $clear_all also unset rev_number, metadata_visibility, and eprint_status fields.

User Comments


remove

$success = $eprint->remove

Erase this eprint data object and any associated data objects from the database and filesystem.

This should only be called on eprints in inbox or buffer.

User Comments


commit

$success = $eprint->commit( [ $force ] );

Commit any changes to the database.

Calls update_triggers just before the database is updated.

The actions this method does are dependent on some object attributes:

 changed - hash of changed fields (from EPrints::DataObj)
 non_volatile_change - boolean (from EPrints::DataObj)
 under_construction - boolean
 

If datestamp is unset and this eprint is in the archive dataset datestamp will always be set which will in turn set datestamp as changed.

If no field values were changed and $force is false returns.

If under_construction is false:

- static files updated

If non_volatile_change is true:

- lastmod field updated
- triples update queued

If under_construction is false and non_volatile_change is true:

- revision generated

The goal of these controls is to only trigger expensive processes in response to user actions. Revisions need to be generated when the user changes metadata or uploads new files (see EPrints::DataObj::Document#commit).

User Comments


save_revision

$eprint->save_revision( %opts )

Increase the eprint revision number and save a complete copy of the record into the history (see EPrints::DataObj::History).

Options:

 user - user that caused the action to occur, defaults to current user
 action - see history.action, defaults to "modify"
 details - see history.details, defaults to a description of changed fields
 

User Comments


validate

$problems = $eprint->validate( [$for_archive], $workflow_id )

Return a reference to an array of XHTML DOM objects describing validation problems with the entire eprint based on $workflow_id.

If $workflow_id is undefined defaults to default.

A reference to an empty array indicates no problems.

Calls validate_eprint for the $eprint.

User Comments


skip_validation

$boolean = $eprint->skip_validation

Returns true if this eprint should pass validation without being properly validated. This is to allow the use of dodgy data imported from legacy systems.

User Comments


prune_documents

$eprint->prune_documents

Remove any documents associated with this eprint that do not actually have any files.

User Comments


get_all_documents

@documents = $eprint->get_all_documents

Return a list of all EPrints::DataObj::Document objects associated with this eprint excluding documents with a isVolatileVersionOf relation, (e.g. thumbnails).

User Comments


move_to_deletion

$success = $eprint->move_to_deletion

Transfer the eprint into the deletion dataset. Should only be called by eprints in the archive dataset.

User Comments


move_to_inbox

$success = $eprint->move_to_inbox

Transfer the eprint into the inbox dataset. Should only be called for eprints in the buffer dataset.

User Comments


move_to_buffer

$success = $eprint->move_to_buffer

Transfer the eprint into the buffer dataset. Should only be called by eprints in the inbox or archive datasets.

User Comments


move_to_archive

$success = $eprint->move_to_archive

Move this eprint into the main archive dataset. Normally only called on eprints in deletion or buffer datasets.

User Comments


local_path

$path = $eprint->local_path

Returns the full path of the eprint data onject directory on the local filesystem with no trailing slash.

User Comments


path

$path = $eprint->path

Returns the full URL path of the eprint data object including a trailing slash. E.g. 1234/.

User Comments


url_stem

$url = $eprint->url_stem

Returns the URL to this eprint's directory.

N.B. This includes the trailing slash, unlike the local_path method.

User Comments


generate_static

$eprint->generate_static

Generate the static version of the abstract/summary web page. In a multi-language repository this will generate one version per language.

If called on eprints in the inbox or buffer, remove the abstract/summary page.

User Comments
