.run(dsl_code_or_name, context = {}) ⇒ Object

If given a symbol as the first parameter, it attempts to run a previously registered job using that name. Alternatively, a string of code can be passed to be parsed and run directly.

Parameters:

    As a symbol, the name of a registered job. As a string, the EXEL code to be run.

  • context (Context, Hash) (defaults to: {})

    (Optional) The initial Context to be passed to the job.

Raises:

  • If no job has been registered with the given name
