==NAME

== EPrints::DataObj::Document - A single format of a record.

User Comments


==DESCRIPTION

== Document represents a single format of an EPrint (eg. PDF) - the 

actual file(s) rather than the metadata.

Inherits from EPrints::DataObj::SubObject, which in turn inherits 

from EPrints::DataObj.

User Comments


==INSTANCE VARIABLES

== See EPrints::DataObj#INSTANCE_VARIABLES.

User Comments


==CORE METADATA FIELDS

==

User Comments


===docid (int)

=

The unique ID of the document.

User Comments


===rev_number (int)

=

The revision number of this document record.

=

The position of the document record within those associated with the 

eprint.

User Comments


===placement (int)

=

Placement of the document - the order documents in which should be 

shown.  This may be different to pos, as the ultimate_doc_pos 
may lead to a different ordering.

User Comments


===format (namedset)

=

The format of this document. One of the types of the namedset 

c<document>.

User Comments


===formatdesc (text)

=

An additional description of this document. For example the specific 

version of a format.

===eprintid (itemref)

=

The ID number of the eprint to which this document belongs.

User Comments


===files (subobject, multiple)

=

A virtual field which represents the list of files which are part of 

this record.

User Comments


===relation (relation, multiple)

===Constructor Methods

=

User Comments


create

$doc = EPrints::DataObj::Document::create( $session, $eprint )

Create and return a new document belonging to the given $eprint 

object.

N.B. This creates the document in the database, not just in memory.

User Comments


create_from_data

$dataobj = EPrints::DataObj::Document::create_from_data( $session, $data, $dataset )

Create document data object from $data provided.

Returns undef if a bad (or no) eprintid specified in $data.

Otherwise calls the parent method in EPrints::DataObj.

User Comments


===Class Methods

=

User Comments


get_system_field_info

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

Returns an array describing the system metadata of the document 

dataset.

User Comments


get_defaults

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

Returns default values for this data object based on the starting 

$data.

User Comments


get_dataset_id

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

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

belongs.

User Comments


get_parent_dataset_id

$dataset_id = EPrints::DataObj::Document->get_parent_dataset_id

Returns the ID of the parent dataset for a document, (i.e. eprint).

User Comments


===Object Methods

=

User Comments


clone

$newdoc = $doc->clone( $eprint )

Attempt to clone this document. Both the document metadata and the 

actual files. The clone will be associated with the given $eprint.

Returns to the newly colument document.

User Comments


remove

$success = $doc->remove

Attempt to completely delete this document. Including derived 

documents such as thumbnails.

Returns boolean dependent on success of deleting document.

User Comments


get_eprint

$eprint = $doc->get_eprint

Returns the eprint this document is associated with.

Alias for: 

$doc->get_parent

User Comments


get_baseurl

$url = $doc->get_baseurl

Returns the base URL of the document.

User Comments


is_public

$boolean = $doc->is_public

Returnes true if this document has no security set and is in the 

live archive. Otherwise, returns false.

User Comments


path

$path = $doc->path

Returns the relative path to the document without specifying any file.

User Comments


file_path

$path = $doc->file_path( [ $file ] )

Returns the relative path to $file stored in this document. 

If $file is undefined returns the path to the main file.

This is an efficient shortcut to this: 

my $file = $doc->stored_file( $filename );
my $path = $file->path;

User Comments


get_url

$url = $doc->get_url( [ $file ] )

Returns the full URL of the document.

If $file is not specified then the main file is used.

User Comments


local_path

DEPRECATED.

Returns the full path of the directory where this document is stored 

in the filesystem.

User Comments


files

%files = $doc->files

Returns a hash, the keys of which are all the files belonging to this 

document (relative to local_path). The values are the sizes of the 
files in bytes.

User Comments


remove_file

$success = $doc->remove_file( $filename )

Attempts to remove the file with $filename. $filename must be 

specified in the format that can be retrieved by get_stored_file.

User Comments


set_main

$doc->set_main( $main_file )

Sets main for the document to the named $main_file and adjusts 

format and mime_type as necessary. Will not affect the database 
until the document is committed.

Unsets main if $main_file is undefined.

User Comments


get_main

$filename = $doc->get_main

Returns the filename of the file set as main in this document.

User Comments


set_format

$doc->set_format( $format )

Set format for document to $format. Will not affect the database

affect the database until document is committed.

Alias for: 

$doc->set_value( "format_desc" , $format_desc );

User Comments


upload

$success = $doc->upload( $filehandle, $filename, [ $preserve_path, $filesize ] )

DEPRECATED - Use add_file, which will automatically identify the 

file type.

Upload the contents of the given $filehandle into this document as 

the given $filename.

If $preserve_path then make any subdirectories needed, otherwise 

place this in the top level directory.

User Comments


add_file

$fileobj = $doc->add_file( $file, $filename, [ $preserve_path ] )

$file is the full path to a file to be added to the document, with

$filename.

Returns the file object if successfully created or undef on 

failure.

User Comments


upload_archive

$success = $doc->upload_archive( $filehandle, $filename, $archive_format )

filename from $filename. How to deal with the specified 
$archive_format (e.g. .zip, .tar.gz) is configured in 
EPrints::SystemSettings.

User Comments


add_archive

$success = $doc->add_archive( $file, $archive_format )
