InheritanceStackOverflowError Inheritance Error Inheritance Object

Language version: ActionScript 3.0
Runtime version: 

ActionScript throws a StackOverflowError exception when the stack available to the script is exhausted. ActionScript uses a stack to store information about each method call made in a script, such as the local variables that the method uses. The amount of stack space available varies from system to system.

A StackOverflowError exception might indicate that infinite recursion has occurred, in which case a termination case needs to be added to the function. It also might indicate that the recursive algorithm has a proper terminating condition but has exhausted the stack anyway. In this case, try to express the algorithm iteratively instead.

Examples
examples\StackOverflowErrorExample
The following example uses the sample StackOverflowErrorExample class to show the error generated in the event of a stack overflow. This is accomplished using the following steps:
  1. The constructor calls the method lockMachine() within an error handling code segment that catches StackOverflowError objects.
  2. The lockMachine() method calls itself until the stack overflows.
  3. After the StackOverflowError is thrown, the constructor catches it and then outputs an error message through the trace statement. 
package {
	import flash.display.Sprite;
	import flash.errors.StackOverflowError;

	public class StackOverflowErrorExample extends Sprite {		
		public function StackOverflowErrorExample() {
			try {
				lockMachine();
			} 
			catch(e:StackOverflowError) {
				trace(e);	// StackOverflowError: Error #1023: Stack overflow.
			}
		}
		
		private function lockMachine():void {
			lockMachine();
		}
	}
}
