  • Method Details

    • printStackTrace

      public static String printStackTrace(Throwable throwable)
      Generate string for specified exception and the cause of this exception (if any).
      Parameters:
      throwable - a Throwable
      Returns:
      the stack trace as a String

    • printStackTrace

      public static String printStackTrace(Throwable throwable, boolean printCascading)
      Generate string for specified exception and if printCascading is true will print all cascading exceptions.
      Parameters:
      throwable - a Throwable
      printCascading - if true will print all cascading exceptions
      Returns:
      the stack trace as a String

    • printStackTrace

      public static String printStackTrace(Throwable throwable, int depth)
      Serialize the specified Throwable to a string. Restrict the number of frames printed out to the specified depth. If the depth specified is 0 then all the frames are converted into a string.
      Parameters:
      throwable - a Throwable
      depth - number of stack trace frames to show
      Returns:
      the stack trace as a String

    • printStackTrace

      public static String printStackTrace(Throwable throwable, int depth, boolean printCascading)
      Generate exception string for specified exception to specified depth and all Cascading exceptions if printCascading is true.
      Parameters:
      throwable - a Throwable
      depth - number of stack trace frames to show
      printCascading - if true will print all cascading exceptions
      Returns:
      the stack trace as a String

    • printStackTrace

      public static String printStackTrace(Throwable throwable, int depth, boolean printCascading, boolean useReflection)
      Generate exception string for specified exception to specified depth and all Cascading exceptions if printCascading is true. If useReflection is true then the method will also attempt to use reflection to find a method with signature Throwable getCause(). This makes it compatible with JDK1.4 mechanisms for nesting exceptions.
      Parameters:
      throwable - a Throwable
      depth - number of stack trace frames to show
      printCascading - if true will print all cascading exceptions
      useReflection - if true will use reflection to handle JDK1.4 nested exceptions
      Returns:
      the stack trace as a String

    • getCause

      public static Throwable getCause(Throwable throwable, boolean useReflection)
      Utility method to get cause of exception.
      Parameters:
      throwable - a Throwable
      useReflection - if true will use reflection to handle JDK1.4 nested exceptions
      Returns:
      cause of specified exception

    • captureStackTrace

      public static String[] captureStackTrace(Throwable throwable)
      Captures the stack trace associated with this exception.
      Parameters:
      throwable - a Throwable
      Returns:
      an array of Strings describing stack frames.

    • splitString

      public static String[] splitString(String string, String onToken)
      Deprecated.
      This is an internal utility method that should not be used
      Splits the string on every token into an array of stack frames.
      Parameters:
      string - the string to split
      onToken - the token to split on
      Returns:
      the resultant array
