Field Details
RESTRICTION_THRESHOLD_VALUE
Value-based restriction comparison. Any node or edge with a RESTRICTIONS_VALUECOMPARED value greater than theRESTRICTION_THRESHOLD_VALUEwill not be included in the graph.See Also:ENABLE_GRAPH_DRAW
If set toTRUE, adds a ‘EDGE_WKTLINE’ column identifier to the specifiedGRAPH_TABLEso the graph can be viewed via WMS; for social and non-geospatial graphs, the ‘EDGE_WKTLINE’ column identifier will be populated with spatial coordinates derived from a flattening layout algorithm so the graph can still be viewed. Supported values:The default value isFALSE.See Also:SAVE_PERSIST
If set toTRUE, the graph will be saved in the persist directory (see the config reference for more information). If set toFALSE, the graph will be removed when the graph server is shutdown. Supported values:The default value isFALSE.See Also:ADD_TABLE_MONITOR
Adds a table monitor to every table used in the creation of the graph; this table monitor will trigger the graph to update dynamically upon inserts to the source table(s). Note that upon database restart, ifSAVE_PERSISTis also set toTRUE, the graph will be fully reconstructed and the table monitors will be reattached. For more details on table monitors, seeGPUdb.createTableMonitor. Supported values:The default value isFALSE.See Also:GRAPH_TABLE
If specified, the created graph is also created as a table with the given name, in [schema_name.]table_name format, using standard name resolution rules and meeting table naming criteria. This table will have the following identifier columns: ‘EDGE_ID’, ‘EDGE_NODE1_ID’, ‘EDGE_NODE2_ID’. If left blank, no table is created. The default value is ”.See Also:REMOVE_LABEL_ONLY
When RESTRICTIONS on labeled entities requested, if set to true this will NOT delete the entity but only the label associated with the entity. Otherwise (default), it’ll delete the label AND the entity. Supported values:The default value isFALSE.See Also:ADD_TURNS
Adds dummy ‘pillowed’ edges around intersection nodes where there are more than three edges so that additional weight penalties can be imposed by the solve endpoints. (increases the total number of edges). Supported values:The default value isFALSE.See Also:TURN_ANGLE
Value in degrees modifies the thresholds for attributing right, left, sharp turns, and intersections. It is the vertical deviation angle from the incoming edge to the intersection node. The larger the value, the larger the threshold for sharp turns and intersections; the smaller the value, the larger the threshold for right and left turns; 0 < turn_angle < 90. The default value is ‘60’.See Also:
