public abstract class StackableException extends Exception
A baseclass for exceptions, which could have parent exceptions. These parent exceptions are raised in a subclass and are now wrapped into a subclass of this Exception.

The parents are printed when this exception is printed. This class exists mainly for debugging reasons, as with them it is easier to detect the root cause of an error.

    • printStackTrace

      public void printStackTrace(PrintStream stream)
      Prints the stack trace to the specified stream.
      Overrides:
      printStackTrace in class Throwable
      Parameters:
      stream - the output stream.
    • printStackTrace

      public void printStackTrace(PrintWriter writer)
      Prints the stack trace to the specified writer.
      Overrides:
      printStackTrace in class Throwable
      Parameters:
      writer - the writer.
    • printStackTrace

      public void printStackTrace()
      Prints this Throwable and its backtrace to the standard error stream. This method prints a stack trace for this Throwable object on the error output stream that is the value of the field System.err. The first line of output contains the result of the Throwable.toString() method for this object. Remaining lines represent data previously recorded by the method Throwable.fillInStackTrace(). The format of this information depends on the implementation, but the following example may be regarded as typical:
       java.lang.NullPointerException
               at MyClass.mash(MyClass.java:9)
               at MyClass.crunch(MyClass.java:6)
               at MyClass.main(MyClass.java:3)
       
      This example was produced by running the program:
      
       class MyClass {
      
           public static void main(String[] argv) {
               crunch(null);
           }
           static void crunch(int[] a) {
               mash(a);
           }
      
           static void mash(int[] b) {
               System.out.println(b[0]);
           }
       }
       
      Overrides:
      printStackTrace in class Throwable
