Class StackTraceElement

java.lang.Object

org.scalajs.javalibintf.StackTraceElement

public final class StackTraceElement
extends java.lang.Object

Scala.js-specific extensions for StackTraceElement.

In the JavaScript ecosystem, it is common practice for stack traces to mention column numbers in addition to line numbers. The official API of StackTraceElement does not allow for representing column numbers, but Scala.js supports them.

This class offers methods to manipulate the extended information of StackTraceElement for Scala.js.

This class only contains static methods. It cannot be instantiated.
