Parameter Descriptions

direction="DIRECTED" | "UNDIRECTED"

specifies whether to consider the input graph as directed or undirected.

Default

UNDIRECTED

DIRECTED

specifies the graph as directed. In a directed graph, each link (i,j) has a direction that defines how something (such as information) can flow over that link. In link (i,j), the flow is from node i to node j. Node i is called the source (tail) node, and node j is called the sink (head) node.

UNDIRECTED

specifies the input graph as undirected. In an undirected graph, each link {i,j} has no direction, and the flow can be in either direction. That is, {i,j} = {j,i}.

display={displayTables}

specifies a list of results tables to send to the client for display.

For more information about specifying the display parameter, see the common displayTables parameter (Appendix A: Common Parameters).

FALSE

Default

FALSE

specifies the index offset for identifiers in the log and results output data tables. For example, if three entities are found, they are labeled entity 1, 2, and 3 by default. If the value of indexOffset is 4, the entities are labeled entity 4, 5, and 6.
