portfolio_caller_base::add_format ( $format )

protectedinherited

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 chat_portfolio_caller::base_supported_formats ( )

static

Return values

array

Reimplemented from portfolio_caller_base.

check_permissions()

chat_portfolio_caller::check_permissions

(

)

Return values

bool

Reimplemented from portfolio_caller_base.

display_name()

static chat_portfolio_caller::display_name ( )

static

Return values

string

Reimplemented from portfolio_caller_base.

expected_callbackargs()

static chat_portfolio_caller::expected_callbackargs ( )

static

Return values

array

Reimplemented from portfolio_caller_base.

expected_time()

chat_portfolio_caller::expected_time

(

)

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 from portfolio_caller_base.

expected_time_file()

portfolio_caller_base::expected_time_file ( )

inherited

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 )

inherited

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 )

inherited

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()

portfolio_module_caller_base::get ( $key )

inherited

Override the parent get function to make sure when we're asked for a course, We retrieve the object from the database as needed.

Parameters

string

$key

the name of get function

Return values

stdClass

Reimplemented from portfolio_caller_base.

get_allowed_export_config()

portfolio_caller_base::get_allowed_export_config ( )

inherited

Similar to the other allowed_config functions if you need export config, you must provide a list of what the fields are.

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 )

finalinherited

Returns a particular export config value.

Subclasses shouldn't need to override this

Parameters

string

$key

the config item to fetch

Return values

null|mixed

of export configuration

get_export_summary()

portfolio_caller_base::get_export_summary ( )

inherited

After the user submits their config, they're given a confirm screen summarising what they've chosen.

This function should return a table of nice strings => values of what they've chosen to be displayed in a table.

Return values

portfolio_caller_base::get_mimetype ( )

inherited

Gets mimetype.

Return values

string
