public static final class QueryGraphRequest.Options
extends Object

Additional parameters

• FORCE_UNDIRECTED: If set to true, all inbound edges and outbound edges relative to the node will be returned. If set to false, only outbound edges relative to the node will be returned. This parameter is only applicable if the queried graph graphName is directed and when querying nodes. Consult Directed Graphs for more details. Supported values:
  • TRUE
  • FALSE
  The default value is FALSE.
• LIMIT: When specified (>0), limits the number of query results. The size of the nodes table will be limited by the limit value. The default value is '0'.
• OUTPUT_WKT_PATH: If true then concatenated wkt line segments will be added as the WKT column of the adjacency table. Supported values:
  • TRUE
  • FALSE
  The default value is FALSE.
• AND_LABELS: If set to true, the result of the query has entities that satisfy all of the target labels, instead of any. Supported values:
  • TRUE
  • FALSE
  The default value is FALSE.
• SERVER_ID: Indicates which graph server(s) to send the request to. Default is to send to the server, amongst those containing the corresponding graph, that has the most computational bandwidth.
• OUTPUT_CHARN_LENGTH: When specified (>0 and <=256), limits the number of char length on the output tables for string based nodes. The default length is 64. The default value is '64'.
• FIND_COMMON_LABELS: If set to true, for many-to-many queries or multi-level traversals, it lists the common labels between the source and target nodes and edge labels in each path. Otherwise (zero rings), it'll list all labels of the node(s) queried. Supported values:
  • TRUE
  • FALSE
  The default value is FALSE.

The default value is an empty Map. A set of string constants for the parameter options.
