Loads edges from a CSV file.
nodeType[in] The type of the edge to load. If it does not exist, it creates it
- Parameters
-
graph [in] The graph to load the edges into fileName [in] The name of the file edgeType null tailNodeType [in] The type of the tail nodes. If it does not exist and onMissingTail is set to "Create", it creates it. Otherwise, an exception is thrown headNodeType [in] The type of the head nodes. It it does not exist and onMissingHead is set to "Create", it creates it. Otherwise, an exception is thrown tail [in] The tail column index. Default: 0 head [in] The head column index. Default: 1 separator [in] The column separator. Default: "," directed [in] True if this edge is directed or not. False otherwise. Default: True header [in] True if the CSV contains a header. False otherwise. Default: True onMissingTail [in] The policy to follow when a tail is missing. Default: "IsError" onMissingHead [in] The policy to follow when a head is missing. Default: "IsError" columns [in] The list of columns to load. tail and head columns must be in this list if this list is specified. If the list is empty, all columns are loaded. Default: empty attrNames [in] The attribute names. If this list is empty and hasHeader is set to true, the header values are used as attribute names. Default: empty dataTypes [in] The dataTypes of the attributes if this do not already exist. If this list is empty, the method tries to infer the data type from the first non-header row. Default: empty attrKinds [in] The attributeKinds of the attributes if these do not already exist. If this list is empty, the attributeKind of the created attributes are set to Basic. Default: empty
