Class StackableException

  • All Implemented Interfaces:
    java.io.Serializable
    Direct Known Subclasses:
    ModuleInitializeException, UnsupportedEncoderException
    public class StackableException
extends java.lang.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.

      • getParent

        public java.lang.Exception getParent()
        Deprecated.
        use the throwable instead.
        Returns the parent exception (possibly null).
        Returns:
        the parent exception.

      • getParentThrowable

        public java.lang.Throwable getParentThrowable()

      • getMessage

        public java.lang.String getMessage()
        Returns the detail message string of this throwable.
        Overrides:
        getMessage in class java.lang.Throwable
        Returns:
        the detail message string of this Throwable instance (which may be null).

      • toString

        public java.lang.String toString()
        Returns a short description of this throwable. If this Throwable object was created with a non-null detail message string, then the result is the concatenation of three strings:
        • The name of the actual class of this object
        • ": " (a colon and a space)
        • The result of the getMessage() method for this object
        If this Throwable object was created with a null detail message string, then the name of the actual class of this object is returned.
        Overrides:
        toString in class java.lang.Throwable
        Returns:
        a string representation of this throwable.

      • printStackTrace

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

      • printStackTrace

        public void printStackTrace​(java.io.PrintWriter writer)
        Prints the stack trace to the specified writer.
        Overrides:
        printStackTrace in class java.lang.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 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 java.lang.Throwable
