==DESCRIPTION==<br />
This virtual class provides some utility methods to objects that are sub-objects of other data objects.<br />
<br />
It expects to find "datasetid" and "objectid" fields to identify the parent object with.<br />

====new_from_data====<br />
<br />
$dataobj = EPrints::DataObj::SubObject-&gt;new_from_data( $session, $data, [ $dataset ] )<br />
Constructs and returns a new sub-object from the <tt>$data</tt> provided.<br />
<br />
Looks for a special <tt>_parent</tt> element in <tt>$data</tt> and uses it to set the parent object, if defined.<br />
<br />
<tt>$dataset</tt> is determined from the class if not provided.<br />
<br />

====create_from_data====<br />
<br />
$dataobj = EPrints::DataObj::SubObject-&gt;create_from_data( $session, $data, [ $dataset ] )<br />
Creates and returns a new sub-object from the <tt>$data</tt> provided.<br />
<br />
Looks for a special '''_parent''' element in $data and uses it to create default values for '''datasetid''' and '''objectid''' if parent is available and those fields exist on the object.<br />
<br />
<tt>$dataset</tt> is determined from the class if not provided.<br />

====get_parent====<br />
<br />
$parent = $dataobj-&gt;get_parent( [ $datasetid, $objectid ] )<br />
Gets and caches the parent data object. If <tt>$datasetid</tt> and/or <tt>$objectid</tt> are specified uses these values rather than the stored values.<br />
<br />
Subsequent calls to <tt>get_parent</tt> will return the cached object, regardless of <tt>$datasetid</tt> and <tt>$objectid</tt>.<br />
<br />
Has alias:<br />
