Detailed Description

Evaluate assertions.

If the runtime is configured to evaluate assertions, it evaluates the given boolean expression. If the expression evaluates to true, nothing happens. If the expression evaluates to false, the execution of OTX procedure will be stopped (the exact runtime behaviour is unspecified), and the failed assertion is reported to the runtime system (out of OTX scope). The errorMessage term, if present, will only be evaluated when the assertion failed. In particular, the errorMessage term cannot throw any exceptions unless the assertion failed. If the runtime is configured not to evaluate assertions, the Assert action does nothing. In particular, the condition and errorMessage terms will not be evaluated, and thus cannot throw any exceptions.

Syntax

Assertion.Assert(BooleanTerm condition, StringTerm errorMessage);

Example

// Local Declarations
 
// Flow
Assertion.Assert(1 == 1, "the expression evaluates to true");
Assertion.Assert(1 != 1, "the expression evaluates to false");
Assertion.Assert((1/0) == 0, "an exception occurs while evaluating the boolean expression");
