Field Summary

Fields

Modifier and Type	Field and Description
static String	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).
static String	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.
static String	ALLOW_MULTIPLE_EDGES Multigraph choice; allowing multiple edges with the same node pairs if set to true, otherwise, new edges with existing same node pairs will not be inserted.
static String	EMBEDDING_TABLE If table exists (should be generated by the match/graph match_embedding solver), the vector embeddings for the newly inserted nodes will be appended into this table.
static String	ENABLE_GRAPH_DRAW If set to TRUE, adds a 'EDGE_WKTLINE' column identifier to the specified GRAPH_TABLE so 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.
static String	EXPORT_CREATE_RESULTS If set to TRUE, returns the graph topology in the response as arrays.
static String	FALSE
static String	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	static String	LABEL_DELIMITER If provided the label string will be split according to this delimiter and each sub-string will be applied as a separate label onto the specified edge.
static String	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.
static String	RESTRICTION_THRESHOLD_VALUE Value-based restriction comparison.
static String	SAVE_PERSIST If set to TRUE, the graph will be saved in the persist directory (see the	static String	TRUE
static String	TURN_ANGLE Value in degrees modifies the thresholds for attributing right, left, sharp turns, and intersections.
static String	USE_RTREE Use an range tree structure to accelerate and improve the accuracy of snapping, especially to edges.

Field Detail

RESTRICTION_THRESHOLD_VALUE

public static final String RESTRICTION_THRESHOLD_VALUE

Value-based restriction comparison. Any node or edge with a RESTRICTIONS_VALUECOMPARED value greater than the RESTRICTION_THRESHOLD_VALUE will not be included in the graph.

Constant Field Values

EXPORT_CREATE_RESULTS

public static final String EXPORT_CREATE_RESULTS

If set to TRUE, returns the graph topology in the response as arrays. Supported values:

• TRUE
• FALSE

The default value is FALSE.

FALSE

public static final String FALSE

ENABLE_GRAPH_DRAW

public static final String ENABLE_GRAPH_DRAW

If set to TRUE, adds a 'EDGE_WKTLINE' column identifier to the specified GRAPH_TABLE so 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:

• TRUE
• FALSE

The default value is FALSE.

Constant Field Values

SAVE_PERSIST

public static final String SAVE_PERSIST

If set to TRUE, the graph will be saved in the persist directory (see the config reference for more information). If set to FALSE, the graph will be removed when the graph server is shutdown. Supported values:

• TRUE
• FALSE

The default value is FALSE.

See Also:

Constant Field Values

ADD_TABLE_MONITOR

public static final String 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, if SAVE_PERSIST is also set to TRUE, the graph will be fully reconstructed and the table monitors will be reattached. For more details on table monitors, see GPUdb.createTableMonitor. Supported values:

• TRUE
• FALSE

The default value is FALSE.

See Also:

Constant Field Values

GRAPH_TABLE

public static final String 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 ''.

Constant Field Values

REMOVE_LABEL_ONLY

public static final String 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:

• TRUE
• FALSE

The default value is FALSE.

See Also:

Constant Field Values

ADD_TURNS

public static final String 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:

• TRUE
• FALSE

The default value is FALSE.

See Also:

Constant Field Values

TURN_ANGLE

public static final String 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'.

Constant Field Values

USE_RTREE

public static final String USE_RTREE

Use an range tree structure to accelerate and improve the accuracy of snapping, especially to edges. Supported values:

• TRUE
• FALSE

The default value is TRUE.

See Also:

Constant Field Values

LABEL_DELIMITER

public static final String LABEL_DELIMITER

If provided the label string will be split according to this delimiter and each sub-string will be applied as a separate label onto the specified edge. The default value is ''.

See Also:

Constant Field Values

ALLOW_MULTIPLE_EDGES

public static final String ALLOW_MULTIPLE_EDGES

Multigraph choice; allowing multiple edges with the same node pairs if set to true, otherwise, new edges with existing same node pairs will not be inserted. Supported values:

• TRUE
• FALSE

The default value is TRUE.

See Also:

Constant Field Values

EMBEDDING_TABLE

public static final String EMBEDDING_TABLE

If table exists (should be generated by the match/graph match_embedding solver), the vector embeddings for the newly inserted nodes will be appended into this table. The default value is ''.
