See “Using the Metadata API Class” on page 14. l_rc N specifies the return codes for the method. A nonzero code indicates failure and means that l_rc is an error list identifier. For the error list format, see “Error Codes” on page 14. reposid.typeid C specifies the passed reposid and typeid of metadata that is to be returned. For the general format of these IDs, see “Identifying Metadata” on page 7. l_objs L spcifies the returned list of metadata objects. List format: id=name. search_ secondary N specifies the passed indicator. Optional. Specifies whether the returned list should include any objects of the specified type from all active secondary repositories. include_subtypes N specifies the passed indicator. Optional. Specifies whether the returned list should include subtypes. Details search_secondary specifies the passed indicator. Optional. Specifies whether the returned list should include any objects of the specified type from all active secondary repositories. 0 — return objects from the passed repository only. Metadata API Class _GET_METADATA_OBJECTS_ 29 1 — (default) if passed repository ID is that of the primary repository, then return all from the secondary repository, too. If passed repository ID is that of a secondary repository, this parameter is ignored. include_subtypes specifies the passed indicator. Optional. Specifies whether the returned list should include subtypes. 0 — return objects of the specified type only. 1 — (default) return objects of the specified type and their subtypes, if any.

See “Using the Metadata API Class” on page 14. l_rc N specifies the return codes for the method. A nonzero code indicates failure and means that l_rc is an error list identifier. For the error list format, see “Error Codes” on page 14. type_id C specifies the passed type ID of metadata to be returned. For the general format of this ID, see “Identifying Metadata” on page 7. l_types L specifies the returned list of all possible subtypes for the specified type. List format: type_id=type_name. expand N specifies the passed indicator. Optional. Specifies whether returned list will expand all possible subtypes of all subtype branches. Details expand specifies the passed indicator. Optional. Specifies whether returned list will expand all possible subtypes of all subtype branches. 0 — (default) return all subtypes unexpanded. 1 — expand all possible subtypes of all subtype branches.
