Exception Handling (Error Runtime Handling)
An exception is an error occurs in the runtime (the excution) of program. The CGScript language uses the try/catch statement and the throw expression to implement the exception handling.
Syntax
try-catch statement
try {
// codes that could throw an exception
}
catch (exception) {
// codes that execute when exception-declaration is thrown in the try block
}
- The exception can be any type (E.g. exception object, number, string...)
- CGScript language does not support multi catch clauses.
throw expression
throw [expression]
- The expression can be any type (E.g. exception object, number, string...)
- If throw is used in catch clause, it will be re-throw. See below examples for information about re-throw.
