-----------------------------------------
Summary: VertexPrograms should declare traverser requirements
Key: TINKERPOP-1280
URL: https://issues.apache.org/jira/browse/TINKERPOP-1280
Project: TinkerPop
Issue Type: Improvement
Components: process
Affects Versions: 3.2.0-incubating
Reporter: Daniel Kuppitz
VertexPrograms should declare their {{TraverserRequirement}} which can then be
propagated by the {{program()}} step. Most VPs (at least the ones I have
written so far) rely on (labeled) path information and thus will fail if the
actual traversal doesn't use any other steps with the same traverser
requirements. I keep running into this issue whenever I write a new VP.
