Constructor & Destructor Documentation

◆ __construct()

portfolio_caller_base::__construct ( $callbackargs )

Create portfolio_caller object.

Parameters

array $callbackargs argument properties

Reimplemented in mod_workshop_portfolio_caller, forum_portfolio_caller, data_portfolio_caller, and assign_portfolio_caller.

Member Function Documentation

◆ add_format()

portfolio_caller_base::add_format ( $format )

protected

Adds a new format to the list of supported formats.

This functions also handles removing conflicting and less specific formats at the same time.

Parameters

string $format one of PORTFOLIO_FORMAT_XX

Return values

void

◆ base_supported_formats()

static portfolio_caller_base::base_supported_formats ( )

static

Base supported formats.

Exceptions

coding_exception

Reimplemented in mod_workshop_portfolio_caller, glossary_entry_portfolio_caller, glossary_full_portfolio_caller, forum_portfolio_caller, data_portfolio_caller, chat_portfolio_caller, and assign_portfolio_caller.

◆ expected_callbackargs()

static portfolio_caller_base::expected_callbackargs ( )

static

Array of arguments the caller expects to be passed through to it.

This must be keyed on the argument name, and the array value is a boolean, whether it is required, or just optional eg array( id => true, somethingelse => false )

Reimplemented in mod_workshop_portfolio_caller, glossary_entry_portfolio_caller, glossary_full_portfolio_caller, forum_portfolio_caller, data_portfolio_caller, chat_portfolio_caller, and assign_portfolio_caller.

◆ expected_time()

portfolio_caller_base::expected_time ( )

abstract

How long does this reasonably expect to take.

Should we offer the user the option to wait..? This is deliberately nonstatic so it can take filesize into account the portfolio plugin can override this. (so for example even if a huge file is being sent, the download portfolio plugin doesn't care )

Reimplemented in mod_workshop_portfolio_caller, glossary_entry_portfolio_caller, glossary_full_portfolio_caller, forum_portfolio_caller, data_portfolio_caller, chat_portfolio_caller, and assign_portfolio_caller.

◆ expected_time_file()

portfolio_caller_base::expected_time_file ( )

Helper method to calculate expected time for multi or single file exports.

Return values

string file time expectation

◆ export_config_form()

portfolio_caller_base::export_config_form	(	&	$mform,
			$instance
	)

If this caller wants any additional config items, they should be defined here.

Parameters

moodleform	$mform	passed by reference, add elements to it.
portfolio_plugin_base	$instance	subclass of portfolio_plugin_base

Reimplemented in data_portfolio_caller.

◆ export_config_validation()

portfolio_caller_base::export_config_validation ( $data )

Just like the moodle form validation function, this is passed in the data array from the form and if a non empty array is returned, form processing will stop.

Parameters

array $data data from form.

◆ get()

Generic getter for properties belonging to this instance outside the subclasses like name, visible etc.

Parameters

string $field property's name

Return values

mixed

Exceptions

portfolio_export_exception

Reimplemented in portfolio_module_caller_base.

◆ get_allowed_export_config()

portfolio_caller_base::get_allowed_export_config ( )

Even if you want to store stuff during export without displaying a form to the user, you can use this.

Return values

array array of allowed keys

Reimplemented in data_portfolio_caller.

◆ get_export_config()

portfolio_caller_base::get_export_config ( $key )

final

Returns a particular export config value.

Subclasses shouldn't need to override this
