URL: http://<db.host>:<db.port>/modify/graph
Update an existing graph network using given nodes, edges, weights, restrictions, and options. IMPORTANT: It’s highly recommended that you review the Graphs and Solvers concepts documentation, and Graph REST Tutorial before using this endpoint.

Input Parameter Description

graph_name
string
Name of the graph resource to modify.
nodes
array of strings
Nodes with which to update existing input parameter nodes in graph specified by input parameter graph_name. Review Nodes for more information. Nodes must be specified using identifiers; identifiers are grouped as combinations. Identifiers can be used with existing column names, e.g., ‘table.column AS NODE_ID’, expressions, e.g., ‘ST_MAKEPOINT(column1, column2) AS NODE_WKTPOINT’, or raw values, e.g., ‘{9, 10, 11} AS NODE_ID’. If using raw values in an identifier combination, the number of values specified must match across the combination. Identifier combination(s) do not have to match the method used to create the graph, e.g., if column names were specified to create the graph, expressions or raw values could also be used to modify the graph.
edges
array of strings
Edges with which to update existing input parameter edges in graph specified by input parameter graph_name. Review Edges for more information. Edges must be specified using identifiers; identifiers are grouped as combinations. Identifiers can be used with existing column names, e.g., ‘table.column AS EDGE_ID’, expressions, e.g., ‘SUBSTR(column, 1, 6) AS EDGE_NODE1_NAME’, or raw values, e.g., ”{‘family’, ‘coworker’} AS EDGE_LABEL”. If using raw values in an identifier combination, the number of values specified must match across the combination. Identifier combination(s) do not have to match the method used to create the graph, e.g., if column names were specified to create the graph, expressions or raw values could also be used to modify the graph.
weights
array of strings
Weights with which to update existing input parameter weights in graph specified by input parameter graph_name. Review Weights for more information. Weights must be specified using identifiers; identifiers are grouped as combinations. Identifiers can be used with existing column names, e.g., ‘table.column AS WEIGHTS_EDGE_ID’, expressions, e.g., ‘ST_LENGTH(wkt) AS WEIGHTS_VALUESPECIFIED’, or raw values, e.g., ‘{4, 15} AS WEIGHTS_VALUESPECIFIED’. If using raw values in an identifier combination, the number of values specified must match across the combination. Identifier combination(s) do not have to match the method used to create the graph, e.g., if column names were specified to create the graph, expressions or raw values could also be used to modify the graph.
restrictions
array of strings
Restrictions with which to update existing input parameter restrictions in graph specified by input parameter graph_name. Review Restrictions for more information. Restrictions must be specified using identifiers; identifiers are grouped as combinations. Identifiers can be used with existing column names, e.g., ‘table.column AS RESTRICTIONS_EDGE_ID’, expressions, e.g., ‘column/2 AS RESTRICTIONS_VALUECOMPARED’, or raw values, e.g., ‘{0, 0, 0, 1} AS RESTRICTIONS_ONOFFCOMPARED’. If using raw values in an identifier combination, the number of values specified must match across the combination. Identifier combination(s) do not have to match the method used to create the graph, e.g., if column names were specified to create the graph, expressions or raw values could also be used to modify the graph.
options
map of string to strings
Optional parameters.The default value is an empty map ( {} ).

Output Parameter Description

status
String
‘OK’ or ‘ERROR’
message
String
Empty if success or an error message
data_type
String
‘modify_graph_response’ or ‘none’ in case of an error
data
String
Empty string
data_str
JSON or String
This embedded JSON represents the result of the /modify/graph endpoint:Empty string in case of an error.
