| | 4 | [wiki:UsersWikiPostgisTopology Topology] editing is currently supported by a partial implementation |
| | 5 | of ISO SQL/MM specification functions. |
| | 6 | |
| | 7 | You can still use SQL UPDATE,SELECT and DELETE commands, but using SQL/MM functions will provide you with a more stable abstraction, will perform some checks and in some cases automatically update TopoGeometry composition records. |
| | 8 | |
| | 9 | All SQL/MM functions have the ST_ prefix in addition to being installed under the ''topology'' schema as every other Topology object. Fully implemented editing functions are: |
| | 10 | |
| | 11 | ST_!InitTopoGeo |
| | 12 | |
| | 13 | Creates a topology, just a wrapper around CreateTopology |
| | 14 | |
| | 15 | St_!AddIsoNode |
| | 16 | |
| | 17 | Adds an IsolatedNode |
| | 18 | |
| | 19 | ST_!RemoveIsoNode |
| | 20 | |
| | 21 | Removes an IsolatedNode |
| | 22 | |
| | 23 | ST_!MoveIsoNode |
| | 24 | |
| | 25 | Move an IsolatedNode in space |
| | 26 | |
| | 27 | ST_!AddIsoEdge |
| | 28 | |
| | 29 | Adds an IsolatedEdge |
| | 30 | |
| | 31 | ST_!RemoveIsoEdge |
| | 32 | |
| | 33 | Removes an IsolatedEdge |
| | 34 | |
| | 35 | ST_!ChangeEdgeGeom |
| | 36 | |
| | 37 | Updates the [wiki:UsersWikiLineStringGeometry curve geometry] of an [wiki:UsersWikiEdgeElement Edge]. |
| | 38 | |
| | 39 | ST_!NewEdgesSplit |
| | 40 | |
| | 41 | Splits an IsolatedEdge with a new [wiki:UsersWikiNodeElement Node]. |
| | 42 | The old Edge will be removed and substituted with the two new Edges resulting from the split. |
| | 43 | Any TopoGeometry object referring to the old Edge will be updated to refer to the new Edges. |
| | 44 | |
| | 45 | ST_!GetFaceGeometry |
| | 46 | |
| | 47 | Returns a face [wiki:UsersWikiGeometryType Geometry] |
