Class StackableException
java.lang.Object
java.lang.Throwable
java.lang.Exception
org.pentaho.reporting.libraries.base.util.StackableException
- All Implemented Interfaces:
Serializable
- Direct Known Subclasses:
ModuleInitializeException
,UnsupportedEncoderException
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.

Method Details
-
getParent
Deprecated.use the throwable instead.Returns the parent exception (possibly null).- Returns:
- the parent exception.
-
getParentThrowable
-
getMessage
Returns the detail message string of this throwable.- Overrides:
getMessage
in classThrowable
- Returns:
- the detail message string of this Throwable instance (which may be null).
-
toString
Returns a short description of this throwable. If thisThrowable
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
Throwable
object was created with a null detail message string, then the name of the actual class of this object is returned. -
printStackTrace
Prints the stack trace to the specified stream.- Overrides:
printStackTrace
in classThrowable
- Parameters:
stream
- the output stream.
-
printStackTrace
Prints the stack trace to the specified writer.- Overrides:
printStackTrace
in classThrowable
- Parameters:
writer
- the writer.

printStackTrace
public void printStackTrace()Prints thisThrowable
and its backtrace to the standard error stream. This method prints a stack trace for thisThrowable
object on the error output stream that is the value of the fieldSystem.err
. The first line of output contains the result of thetoString()
method for this object. Remaining lines represent data previously recorded by the methodThrowable.fillInStackTrace()
. The format of this information depends on the implementation, but the following example may be regarded as typical:
This example was produced by running the program:java.lang.NullPointerException at MyClass.mash(MyClass.java:9) at MyClass.crunch(MyClass.java:6) at MyClass.main(MyClass.java:3)
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]); } }
