Summary: assert step
Key: TINKERPOP3-717
URL: https://issues.apache.org/jira/browse/TINKERPOP3-717
Project: TinkerPop 3
Issue Type: Improvement
Components: process
Reporter: Matt Frantz
Assignee: Marko A. Rodriguez
Consider a step that allows specifying a traversal that must be proven. In
conjunction with a strategy that removes such steps for "production", this
would provide the "assert" capability in many languages.
{code}
GraphTraversal assert(Traversal t)
{code}
The logic would be that if {{t}} does not produce a traverser, then an
assertion exception would be raised.
We probably can't call it {{assert}} because it is a reserved word in many
languages.
