Exception

Base class for exceptions.

If this class (or derivatives) is used to catch an exception, then haxe.CallStack.exceptionStack() will not return a stack for the exception caught. Use haxe.Exception.stack property instead:

try {
throwSomething();
} catch(e:Exception) {
trace(e.stack);
}

Custom exceptions should extend this class:

class MyException extends haxe.Exception {}
//...
throw new MyException('terrible exception');

haxe.Exception is also a wildcard type to catch any exception:

try {
throw 'Catch me!';
} catch(e:haxe.Exception) {
trace(e.message); // Output: Catch me!
}

To rethrow an exception just throw it again. Haxe will try to rethrow an original native exception whenever possible.

try {
var a:Array<Int> = null;
a.push(1); // generates target-specific null-pointer exception
} catch(e:haxe.Exception) {
throw e; // rethrows native exception instead of haxe.Exception
}
