OrientDB shortestPath () using a specific @class edge?

Question

The function shortestPath()takes direction as the third argument. How to change a function so that it intersects only the edges of a certain class? I believe that I can simply add the class as the second argument on line 106:

If I do this, do I need to rebuild from the source code? How can I create a custom function to use in my queries?

Answer 1

OrientDB v.2.0.9 2.1. , , ( "2.0.x" "develop" )

:

shortestPath(<sourceVertex>, <destinationVertex>, [<direction>, [ <edgeTypeAsString> ]])

SELECT shortestPath(#12:0, #12:10, null, "MyEdgeClass")
