------------------------------------
Summary: Add getter for vertex properties in vertex programs
Key: TINKERPOP-2745
URL: https://issues.apache.org/jira/browse/TINKERPOP-2745
Project: TinkerPop
Issue Type: Improvement
Reporter: Boxuan Li
Many if not all vertex programs will mutate vertex properties during the
computation process. For graphs that enforce a schema, this could lead to
failure. JanusGraph, for example, when used with FulgoraGraphComputer and
disabled automatic schema maker, will report error for vertex programs. See
[https://gitter.im/janusgraph/janusgraph?at=626c568910cfc315bc5781a0]
This ticket proposes a getter method for each vertex program, which would
return the vertex properties together with their data types needed in the
computation. The graph providers or users could then leverage this information
to create the corresponding schema.
