class Traversal[A] extends IterableOnce[A] with IterableOps[A, Traversal, Traversal[A]] with IterableFactoryDefaults[A, Traversal]

TODO more docs

Just like Tinkerpop3 and most other Iterators, a Traversal can only be executed once. Since this may trip up users, we'll log a warning

    Branch step: based on the current element, match on something given a traversal, and provide resulting traversals based on the matched element. Allows to implement conditional semantics: if, if/else, if/elseif, if/elseif/else, ...

    BranchOn

    required to be >: Null because the implementation is using null as the default value. I didn't find a better way to implement all semantics with the niceties of PartialFunction, and also yolo...

    NewEnd

    Repeat the given traversal

    Repeat the given traversal

    By default it will continue repeating until there's no more results, not emit anything along the way, and use depth first search.

    The @param behaviourBuilder allows you to configure end conditions (times/until), whether it should emit elements it passes by, and which search algorithm to use (depth-first or breadth-first).

    Search algorithm: Depth First Search (DFS) vs Breadth First Search (BFS): DFS means the repeat step will go deep before wide. BFS does the opposite: wide before deep. For example, given the graph 

    L3 <- L2 <- L1 <- Center -> R1 -> R2 -> R3 -> R4

    DFS will iterate the nodes in the order: 

    Center, L1, L2, L3, R1, R2, R3, R4

    BFS will iterate the nodes in the order: 

    Center, L1, R1, R1, R2, L3, R3, R4
    Annotations
    @Doc(short = "repeat the given traversal", long = help.this.Doc.<init>$default$2, example = help.this.Doc.<init>$default$3)
    Example:

    1. .repeat(_.out)                            // repeat until there's no more elements, emit nothing, use DFS
.repeat(_.out)(_.times(3))                               // perform exactly three repeat iterations
.repeat(_.out)(_.until(_.property(Name).endsWith("2")))  // repeat until the 'Name' property ends with '2'
.repeat(_.out)(_.emit)                                   // emit everything along the way
.repeat(_.out)(_.emit.breadthFirstSearch)                // emit everything, use BFS
.repeat(_.out)(_.emit(_.property(Name).startsWith("L"))) // emit if the 'Name' property starts with 'L'
    Note

    this works for domain-specific steps as well as generic graph steps - for details please take a look at the examples in RepeatTraversalTests: both .followedBy and .out work.
