Dear Friends,
I m working neo4j in java. I have some paths and i m trying to find some
relations. I have two problems according to below example. If it is
possible, I will be waiting your answers.
for (Path path :
graphDb.traversalDescription().depthFirst().uniqueness(Uniqueness.NODE_PATH)
.evaluator(Evaluators.atDepth(3))
.relationships(relation.A), Direction.BOTH)
.relationships(relation.B), Direction.BOTH)
.relationships(relation.C, Direction.BOTH)
.traverse(node)) {
}
1. I want to use each relation just one time.
For example: (1)--[A]-->(2)--[A]-->(3)--[B]-->(4) it is not available
for me - A is used two times
(1)--[C]-->(2)--[A]-->(3)--[B]-->(4) it is
available - each relation is unique
2. I want to use relations in order or priority.
For example: (1)--[B]-->(2)--[A]-->(3)--[C]-->(4) it is not
available for me because in my path B is first relationship
(1)--[A]-->(2)--[B]-->(3)--[C]-->(4) it is
available - each relation is in an order
Note: I can solve some other java codes about these, but running time is
slowing.
Best regards.
