What import do i need for inV() and hasID() in gremlin groovy (3.0.1-incubating) -

-

i'm trying property value of edge given source , dest vertex ids, , edge label.

in gremlin terminal following worked:

g.v("fromnodeid").oute("edgelabel").where(inv().hasid("tonodeid")).values("edgeprop")

sadly, in groovy, inv() , hasid() aren't recognized, , can't find correct import work.

here imports iv'e tried:

import org.apache.commons.configuration.configuration; import org.apache.tinkerpop.gremlin.process.traversal.dsl.graph.graphtraversalsource import org.apache.tinkerpop.gremlin.process.* import org.apache.tinkerpop.gremlin.groovy.* import org.apache.tinkerpop.gremlin.groovy.function.* import org.apache.tinkerpop.gremlin.groovy.util.* import org.apache.tinkerpop.gremlin.pipes.filter.* import org.apache.tinkerpop.gremlin.structure.edge import org.apache.tinkerpop.gremlin.structure.vertex import org.apache.tinkerpop.gremlin.structure.edgetest; import org.apache.tinkerpop.gremlin.structure.graph

i'll note other queries s.a. following work fine:

string getpropvaluebyid(long id, string prop){     def result = []     **g.v(id).values(prop).fill(result)**     if(result.empty) return null      return result.first() }

this described in tinkerpop3 documentation

to reduce verbosity of expression, import static org.apache.tinkerpop.gremlin.process.traversal.dsl.graph.__.*. way, instead of doing __.ine() anonymous traversal, possible write ine(). aware of language-specific reserved keywords when using anonymous traversals. example, in , reserved keywords in groovy, therefore must use verbose syntax __.in() , __.as() avoid collisions.

i have been playing around irb , have string looks this: irb(main):072:0> puts ["[\"4354 5432 5432 xxxxx\", \"6547 6547 8543 xxxxx\", \"2344 6543 6674 xxxxx\", \"2346 6236 7543 xxxxx\", \"1273 5585 5587 xxxxx\"]"] => nil irb(main):073:0> what want gsub last 2 "x" s of each 17 digit combination, 23 . what i've tried far (i've been using rubular): a.gsub(/\d[x]/,"23") <= grabs "x" s i'm close a.gsub(/\w[x{2}]/,"23") <= grabs "x" s grabs two digits each combination. is there easier way i'm not understanding? a.gsub(/\d{4} \d{4} \d{4} xxx\kxx/, '23') \d{4} = 4 digits what \k drop matched far. can use don't replace entire number, still able validate have in desired format.
