Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

Contain the validation pipeline and expose the results.

  1. Checks in #initialize:
    • Rescue a ParseError, halt if there is one
    • Check for selected operation, halt if not found
  2. Validate the AST, halt if errors
  3. Validate the variables, halt if errors
  4. Run query analyzers, halt if errors

#valid? is false if any of the above checks halted the pipeline.
