> Key: CALCITE-955
> URL: https://issues.apache.org/jira/browse/CALCITE-955
> Project: Calcite
> Issue Type: Bug
> Reporter: Julian Hyde
> Assignee: Julian Hyde
> Fix For: 1.6.0
>
>
> Calcite has several methods that check internal consistency that have a
> 'boolean fail' argument indicating whether the method should throw or just
> return false if a consistency error is detected.
> We propose to add a class Litmus:
> {code}interface Litmus {
> boolean fail(String message);
> boolean succeed();
> }{code}
> and replace those {{boolean fail}} with {{Litmus litmus}}, so that the caller
> can determine policy on how to handle failures.
> Methods affected include:
> * RelNode.isValid(boolean)
