@brief The _paths function returns all paths of a graph.

graph._paths(options)

This function determines all available paths in a graph.

The complexity of this method is O(n*n*m) with n being the amount of vertices in the graph and m the average amount of connected edges;

@PARAMS

@PARAM{options, object, optional} An object containing options, see below:

  • direction : The direction of the edges. Possible values are any, inbound and outbound (default).
  • followCycles (optional) : If set to true the query follows cycles in the graph, default is false.
  • minLength (optional) : Defines the minimal length a path must have to be returned (default is 0).
  • maxLength (optional) : Defines the maximal length a path must have to be returned (default is 10).

@EXAMPLES

Return all paths of the graph "social":

@EXAMPLE_ARANGOSH_OUTPUT{generalGraphModulePaths} var examples = require("@arangodb/graph-examples/example-graph.js"); var g = examples.loadGraph("social"); g._paths(); ~ examples.dropGraph("social"); @END_EXAMPLE_ARANGOSH_OUTPUT

Return all inbound paths of the graph "social" with a maximal length of 1 and a minimal length of 2:

@EXAMPLE_ARANGOSH_OUTPUT{generalGraphModulePaths2} var examples = require("@arangodb/graph-examples/example-graph.js"); var g = examples.loadGraph("social"); g._paths({direction : 'inbound', minLength : 1, maxLength : 2}); ~ examples.dropGraph("social"); @END_EXAMPLE_ARANGOSH_OUTPUT
