DESCRIPTION
SYSTEM METADATA
METHODS
get_system_field_info
$metadata = EPrints::DataObj::EPM->get_system_field_info
Return an array describing the system metadata of the EPrint dataset.
map
EPrints::DataObj::EPM->map( $repo, sub { ... }, $ctx )
Apply a function over all installed EPMs.
sub {
my( $repo, $dataset, $epm [, $ctx ] ) = @_;
}
This loads the EPM index files only.
new
$epm = EPrints::DataObj::EPM->new( $repo, $id )
Returns a new object representing the installed package $id.
new_from_manifest
$epm = EPrint::DataObj::EPM->new_from_manifest( $repo, $epdata [, @manifest ] )
Makes and returns a new EPM object based on a manifest of installable files.
commit
$epm->commit
Commit any changes to the installed .epm, .epmi files.
rebuild
$epm->rebuild
Reload all of the installed files (regenerating hashes if necessary).
version
$v = $epm->version
Returns a stringified version suitable for string gt/lt matching.
is_enabled
$bool = $epm->is_enabled
Returns true if the $epm is enabled for the current repository.
repositories
@repoids = $epm->repositories
Returns a list of repository ids this $epm is enabled in.
package_filename
$filename = $epm->package_filename()
Returns the complete package filename.
epm_dir
$dir = $epm->epm_dir
Path to the epm directory for this $epm.
installed_files
@files = $epm->installed_files()
Returns a list of installed files as EPrints::DataObj::File.
repository_files
@files = $epm->repository_files()
Returns the list of configuration files used to enable/configure an $epm.
control_screen
$screen = $epm->control_screen( %params )
Returns the control screen for this $epm. %params are passed to the plugin constructor.
serialise
$epm->serialise( $fh, [ FILES ] )
Serialises this EPM to the open file handle $fh. If FILES is true file contents are included.
install
$ok = $epm->install( HANDLER [, FORCE ] )
Install the EPM into the system. HANDLER is a EPrints::CLIProcessor or EPrints::ScreenProcessor, used for reporting errors.
uninstall
$ok = $epm->uninstall( HANDLER [, FORCE ] )
Remove the EPM from the system. HANDLER is a EPrints::CLIProcessor or EPrints::ScreenProcessor, used for reporting errors.
disable_unchanged
$ok = $epm->disable_unchanged()
Remove unchanged files from the repository directory. This allows a new version of the EPM to be installed/enabled.
enable
$ok = $epm->enable( $handler )
Enables the $epm for the current repository.
Utility Methods
current_counters
$conf = $epm->current_counters()
current_datasets
$conf = $epm->current_datasets()
update_counters
$ok = $epm->update_counters( $conf )
update_datasets
$ok = $epm->update_datasets( $conf )
Update the datasets following any configuration changes made by the extension on being enabled. $conf should be retrieved before enabling by using current_datasets.
