Method ObserveEval

interpreter/interpretable.go:171–173

ObserveEval evaluates an interpretable and performs per-evaluation state-tracking. This method is concurrency safe and the expectation is that the observer function will use a switch statement to determine the type of the state which has been reported back from the call.

(vars Activation, observer func(any))

// This method is concurrency safe and the expectation is that the observer function will use
// a switch statement to determine the type of the state which has been reported back from the call.
func (oi *ObservableInterpretable) ObserveEval(vars Activation, observer func(any)) ref.Val {
	return oi.ObserveExec(AsFrame(vars), observer)
