NAME

Embperl::Form::DataSource - Base class for data source objects which provides the data for ControlMutlValue objects.

SYNOPSIS

Do not use directly, instead derive a class

DESCRIPTION

This class is not used directly, it is used as a base class for all data source objects. It provides a set of methods that could be overwritten to customize the behaviour of your controls.

METHODS

get_values

returns the values and options. Must be overwritten.

get_id_from_value

returns an id for a given value. This allows one to have an id form a value/option pair which is not exactly the same as the value. This is used in json requests for example for selectdyn control.

get_datasource_controls

returns additional controls provided by the datasource object e.g. a browse button
