NAME
EPrints::Plugin::Import
METHODS
new
$plugin = EPrints::Plugin::Import->new( %params )
Creates a new Import plugin. In addition to those parameters defined by EPrints::Plugin:
- accept
- Array reference of acceptable MIME types. By default includes application/x-eprints-import-XXX, where XXX is the case-insensitive id of the plugin.
- actions
- Array reference of named actions.
- advertise
- Boolean for whether to advertise this plugin to users.
- arguments
- Hash reference of supported arguments/default values.
- Handler
- Reference to a handler class, typically EPrints::CLIProcessor or EPrints::ScreenProcessor.
- produce
- Array reference of object types this plugin can produce.
- screen
- The screen id this plugin uses to provide its import UI.
- visible
- "staff" (staff only) or "all" (anyone).
handler
$handler = $plugin->handler()
Returns the Handler object, which is used for messages and object creation.
set_handler
$plugin->set_handler( $handler )
Set the handler object.
can_input
$ok = $plugin->can_input( TYPE )
Supports user input via:
- textarea
- Paste into a text area.
- file
- Upload a file.
- form
- Calls $plugin->render_input_form() to render an input form.
input_fh
$plugin->input_fh( fh => FILEHANDLE [, %opts] )
Import one or more objects from FILEHANDLE. FILEHANDLE should be set to binary semantics using perlfunc/binmode.
This method should by subclassed.
input_file
$plugin->input_file( filename => FILENAME [, %opts] )
Opens FILENAME for reading, sets binary semantics and calls input_fh to actually read the file.
This method may be subclassed (e.g. see EPrints::Plugin::Import::TextFile).
epdata_to_dataobj
$dataobj = $plugin->epdata_to_dataobj( $epdata, %opts )
Turn $epdata into a EPrints::DataObj using the dataset argument passed in %opts.
Uses the handler object to perform the actual object creation.
When sub-classing you must call epdata_to_dataobj in order to correctly handle the parse-only and test phases during import.
warning
$plugin->warning( $text )
Generate a warning message using $text.
error
$plugin->error( $text )
Generate an error message using $text.
is_tool
$bool = $plugin->is_tool()
Returns true if this plugin is a tool that should be rendered as a link.
