Examples of org.openquark.cal.runtime.CALExecutorException

org.openquark.cal.runtime.CALExecutorException
Base class for exceptions involved in evaluating CAL code.
The exception hierarchy is divided into two main branches, one for external exceptions and one for internal exceptions.
Internal exceptions are errors in the implementation of CAL, or errors in setting up the CAL services calls to activate the run-time i.e. they are not caused by the correct operation of the running CAL code.
External exceptions are errors in a CAL program. External errors can originate in several ways (currently).
1. A call to the CAL Prelude.error function.
2. A foreign function an exception.
3. An arithmetic exception, such as divide by zero, occurs in evaluating the CAL code.
4. A pattern matching failure, such as (case Just 10.0 of Nothing -> "ok";) or (Left 2.0 :: Either Double Double).Right.value
