Question
What is the use of catch in escript?
Answers
The catch clause is used to handle the exception. To raise an exception, use the throw statement.
When you want to trap potential errors generated by a block of code, place that code in a try statement, and follow the try statement with a catch statement. The catch statement is used to process the exceptions that may occur in the manner you specify in the exception_handling_block.
The following example demonstrates the general form of the try statement with the catch clause. In this example, the script continues executing after the error message is displayed:
try
{
do_something;
}
catch( e )
{
TheApplication().RaiseErrorText(Clib.rsprintf(
"Something bad happened: %s
",e.toString()));
