Description
In order to improve error handling at CTL2, introduce try-catch statement. If an exception is thrown by a statement in try block, then catch block is executed.
try {
//try block
} catch (CTLException e) {
//catch block
}
CTLException is of type record and have following fields:
- sourceRow - integer
- sourceColumn - integer
- message - string - error message from the deepest/inner-most exception - i.e. the original reason for failure
- cause - string - name of the exception which caused this
- stackTrace - list[string] - hierarchy of function call frames on stack
- exceptionTrace - list[string] - list of exception types from the top-most down to inner-most
Try-catch blocks can be nested in other try-catch blocks:
try {
a = b/c;
} catch (CTLException myex1) {
try {
a = b/d;
} catch (CTLException myex2) {
a = INT_CONSTANT;
}
}
