DataModel.getTypedValueAt

Upon errors null will be returned and error will be assigned a #GError from the #GDA_DATA_MODEL_ERROR domain.

This method is similar to gda.data_model.DataModel.getValueAt, except that it also allows one to specify the expected #GType of the value to get: if the data model returned a #GValue of a type different than the expected one, then this method returns null and an error code.

Note: the same limitations and usage instructions apply as for gda.data_model.DataModel.getValueAt.

Upon errors null will be returned and error will be assigned a #GError from the #GDA_DATA_MODEL_ERROR domain.
