Description

SDO_DAS_Relational::createRootDataObject
( void

WarningThis function is
EXPERIMENTAL. The behaviour of this function, its name, and
surrounding documentation may change without notice in a future release of PHP.
This function should be used at your own risk.
Returns the special root object at the top of an otherwise
empty data graph.
This call is used when the application wants to create a
data graph from scratch, without having called
executeQuery()
to create a data graph.
The special root object has one multi-valued containment property,
with a name of the application root type that was passed when
the Relational DAS was constructed.
The property can take values of only that type.
The only thing that the application can usefully do with the root
type is to call
createDataObject()
on it, passing the name of the application root type,
in order to create a data object of their own application type.
Return Values
The root object.
Examples
Please see the
Examples
section in the general information about the Relational DAS
for many examples of calling this method.
