Member Function Documentation

◆ add_format()

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$formatone of PORTFOLIO_FORMAT_XX
Return values
void

◆ base_supported_formats()

static portfolio_caller_base::base_supported_formats ( )
staticinherited

◆ check_permissions()

portfolio_caller_base::check_permissions ( )
abstractinherited

Callback to do whatever capability checks required in the caller (called during the export process.

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

◆ display_name()

static portfolio_caller_base::display_name ( )
staticinherited

◆ expected_callbackargs()

static portfolio_caller_base::expected_callbackargs ( )
staticinherited

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

◆ expected_time()

portfolio_caller_base::expected_time ( )
abstractinherited

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 assign_portfolio_caller, chat_portfolio_caller, data_portfolio_caller, forum_portfolio_caller, glossary_entry_portfolio_caller, glossary_full_portfolio_caller, and mod_workshop_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
stringfile 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.

moodleform$mformpassed by reference, add elements to it.
portfolio_plugin_base$instancesubclass of portfolio_plugin_base

Reimplemented in data_portfolio_caller.

◆ export_config_validation()

portfolio_caller_base::export_config_validation ( $data)

Reimplemented in data_portfolio_caller.

◆ get_export_config()
