Method Detail
captureStackTrace
static captureStackTrace(error : Error, constructorOpt : Function) : void
Fills the stack property for the passed error.
The optional constructorOpt parameter allows you to pass in a function value. When collecting the stack trace all frames above the topmost call to this function, including that call, are left out of the stack trace. This can be useful to hide implementation details that won’t be useful to the user. The usual way of defining a custom error that captures a stack trace would be:
 function MyError() {
     // fill the stack trace, but hide the call to MyError
     Error.captureStackTrace(this, MyError);
 }
 
API Versioned:
From version 21.2.
Parameters:
error - The error whose stack trace should be filled.
constructorOpt - An optional filter to hide the topmost stack frames.

toString
toString() : String
Returns a String representation of the Error.
Returns:
a String representation of the Error.
