Gremlin | fold | reducing barrier | fold-step | There are situations when the traversal stream needs a "barrier" to aggregate all the objects and emit a computation that is a function of the aggregate. The fold()-step (map) is one particular instance of this. Please see unfold()-step for the inverse functionality. | 3 | ||
Gremlin | has | filter | has-step | has-java.lang.String- | filters vertices, edges, and vertex properties based on their properties. This step has quite a few variations. | 2 | |
Gremlin | hasNext | terminal | terminal-steps | determines whether there are available results | 2 | ||
Gremlin | id | map | id-step | maps the traversal to the ids of the current elements. | 2 | ||
Gremlin | in | flatMap | maps the current elements to the vertices at the end of the ingoing edges. | 2 | |||
Gremlin | inE | flatMap | maps the current elements to the the ingoing edges. | 2 | |||
Gremlin | inV | flatMap | maps the current edges to the the ingoing Vertices. | 2 | |||
Gremlin | is | filter | is-step | is-org.apache.tinkerpop.gremlin.process.traversal.P- | filters elements that fullfill the given predicate. Variant: Filters elements that are equal to the given Object. | 2 | |
Gremlin | iterate | terminal | terminal-steps | Iterates the traversal presumably for the generation of side-effects. See https://stackoverflow.com/questions/47403296/iterate-step-is-used-in-the-end-of-the-command-when-creating-nodes-and-edges-t | 2 | ||
Gremlin | label | map | label-step | maps the traversal to the labels of the current elements. | 2 | ||
Gremlin | limit | filter | limit-step | ||||
Gremlin | map | general | general-steps | transforms the current step element to a new element (which may be empty). see also https://stackoverflow.com/questions/51015636/in-gremlin-how-does-map-really-work | 2 | ||
Gremlin | match | map | match-step | see https://stackoverflow.com/questions/55609832/is-threre-a-document-about-how-gremlin-match-works | 2 | ||
Gremlin | max | reducing barrier | max-step | operates on a stream of comparable objects and determines which is the last object according to its natural order in the stream. | 3 | ||
Gremlin | mean | reducing barrier | mean-step | operates on a stream of numbers and determines the average of those numbers. | 3 | ||
Gremlin | min | reducing barrier | min-step | operates on a stream of comparable objects and determines which is the first object according to its natural order in the stream. | 3 | ||
Gremlin | next | terminal | terminal-steps | will return the next result.next(n) will return the next n results in a list | 2 | ||
Gremlin | option | modulator | option-step | An option to a branch() or choose() | 2 | ||
Gremlin | or | filter | or-step | or-org.apache.tinkerpop.gremlin.process.traversal.Traversal...- | ensures that at least one of the provided traversals yield a result. | 2 | |
Gremlin | order | map | order-step | order--,order-org.apache.tinkerpop.gremlin.process.traversal.Scope- | orders the traversal elements | 2 |
