Cole Greer updated TINKERPOP-3015: ---------------------------------- Component/s: process > Use wildcard instead of Object for hasId predicates > --------------------------------------------------- > > Key: TINKERPOP-3015 > URL: https://issues.apache.org/jira/browse/TINKERPOP-3015 > Project: TinkerPop > Issue Type: Improvement > Components: process > Affects Versions: 3.5.7, 3.6.5 > Reporter: Christopher Smith > Priority: Minor > > From both {{GraphTraversal}} and {{__}}, the {{hasId(P)}} steps specify a > {{P<Object>}}. Common predicates, such as {{within}}, propagate the generic > type from their own arguments, so that this produces a compile-time error: > {code} > Collection<String> ids = ... > g.V().hasId(P.within(ids)) > {code} > I believe that without loss of safety, the signature in both locations could > be changed to {{P<?>}}, making the typical case of "here's a collection of > IDs of known type" work smoothly. -- This message was sent by Atlassian Jira (v8.20.10#820010)
