.SH "NAME"
Embperl::Form::DataSource \- Base class for data source objects
which provides the data for ControlMutlValue objects.
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
Do not use directly, instead derive a class
.SH "DESCRIPTION"
.IX Header "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.
.SH "METHODS"
.IX Header "METHODS"
.SS "get_values"
.IX Subsection "get_values"
returns the values and options. Must be overwritten.
.PP
\fIget_id_from_value\fR
.IX Subsection "get_id_from_value"
.PP
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.
.PP
\fIget_datasource_controls\fR
.IX Subsection "get_datasource_controls"
.PP
returns additional controls provided by the
datasource object e.g. a browse button
