Servlet::Util::ExceptiUser)Contributed Perl DocumenServlet::Util::Exception(3)

NAME
       Servlet::Util::Exception	- exception base class

SYNOPSIS
	 eval {
	     Servlet::Util::Exception->throw("oops");
	 };

	 if ($@) {
	     warn "caught exception: $@\n";
	 }

DESCRIPTION
       This is a base class for	exceptions. It extends Exception::Class::Base.
       See Exception::Class for	a full list of inherited methods.

       There is	only one exception to the inherited API: tracing is on by
       default.	This means that	a stack	trace will be created when an
       exception is thrown. By way of comparison to java.lang.Throwable, it's
       as if "fillInStackTrace()" is automatically called inside "throw()". To
       selectively disable tracing for a subclass, do the following:

	 My::Exception::do_trace(0);

CONSTRUCTOR
       new($msg)
	   Construct an	instance with the given	error message.

	   Exceptions are rarely directly constructed. Usually they are
	   constructed and thrown in one call to "throw()".

	   Parameters:

	   $msg
	       the error message

CLASS METHODS
       throw($msg)
	   Constructs an instance with the given error essage and then
	   "die()"s.

	   Parameters:

	   $msg
	       the error message

METHODS
       getMessage()
	   Returns the error message.

       toString()
	   Returns a short description of the exception, including the stack
	   trace if the	exception has been thrown.

EXCEPTION SUBCLASSESS
       These commonly encountered exceptions are provided as utilities.

       Servlet::Util::IOException
	   Thrown to indicate than an I/O exception of some sort has occurred.

       Servlet::Util::IllegalArgumentException
	   Thrown to indicate that a method has	been passed an illegal or
	   inappropriate argument.

       Servlet::Util::IllegalStateException
	   Thrown to indicate that a method has	been invoked at	an illegal or
	   inappropriate time.

       Servlet::Util::IndexOutOfBoundsException
	   Thrown to indicate that an index of some sort (such as to an	array)
	   is out of range.

       Servlet::Util::UndefReferenceException
	   Thrown to indicate that undef was used in a case where a value is
	   required.

       Servlet::Util::UnsupportedEncodingException
	   Thrown to indicate that the chosen character	encoding is
	   unsupported by the environment (most	commonly encountered during
	   character conversions on byte streams).
