    Methods
    Modifier and Type | Method and Description
    --- | ---
    `int` | `columnNumber()` The column number of the location of the error, or zero if unknown.
    `java.lang.String` | `details()`
    `java.lang.String` | `getMessage()`
    `ScriptStackElement[]` | `getScriptStack()` Get the script stack of this exception as an array of `ScriptStackElement`s.
    `ScriptStackElement[]` | `getScriptStack(int limit, java.lang.String hideFunction)` Get the script stack of this exception as an array of `ScriptStackElement`s.
    `java.lang.String` | `getScriptStackTrace()` Get a string representing the script stack of this exception.
    `java.lang.String` | `getScriptStackTrace(java.io.FilenameFilter filter)` Deprecated. the filter argument is ignored as we are able to recognize script stack elements by our own. Use #getScriptStackTrace() instead.

    `static void` | `useMozillaStackStyle(boolean flag)` Tell subclasses of `RhinoException` whether to use the Mozilla/Firefox style of rendering script stacks (`functionName()@fileName:lineNumber`) instead of Rhino's own Java-inspired format (`at fileName:lineNumber (functionName)`).

    - #### getScriptStackTrace

          public java.lang.String getScriptStackTrace()

      Get a string representing the script stack of this exception. If optimization is enabled, this includes java stack elements whose source and method names suggest they have been generated by the Rhino script compiler.
