The throw statement

The throw statement causes an exception to be thrown. If it is not caught by a try-catch in that action or any calling actions, then the monitor instance is terminated along with any listeners it has. The syntax is:

throw expression;

where expression must be of the Exception type.

Example:

action getAverageReading() returns float {
if readingsCount <= 0 {
throw Exception("No readings", "IllegalArgumentException");
}
return readingsSum / readingsCount.toFloat();
}
