4.33 SDO_TOPO_MAP.GET_NODE_DELETIONS
Format
SDO_TOPO_MAP.GET_NODE_DELETIONS() RETURN SDO_NUMBER_ARRAY;
Description
Returns an array of node ID numbers of nodes that have been deleted from the current updatable TopoMap object.
Parameters
None.
Usage Notes
This function returns the node ID numbers of nodes in the current updatable TopoMap object that have been deleted since the object was most recently loaded (using SDO_TOPO_MAP.LOAD_TOPO_MAP), updated (using SDO_TOPO_MAP.UPDATE_TOPO_MAP), cleared (using SDO_TOPO_MAP.CLEAR_TOPO_MAP), committed (using SDO_TOPO_MAP.COMMIT_TOPO_MAP), or rolled back (using SDO_TOPO_MAP.ROLLBACK_TOPO_MAP). If there have been no deletions during that time, the function returns an empty SDO_NUMBER_ARRAY object.
This function is equivalent to using the getNodeDeletions
method of the TopoMap
class of the client-side Java API (described in Topology Data Model Java Interface).
Examples
The following example returns the node ID numbers of nodes that have been deleted from the current updatable TopoMap object. In this case, the return of an empty SDO_NUMBER_ARRAY object indicates that no nodes have been deleted.
