NAME

       Alzabo::Exceptions - Creates all exception subclasses used in Alzabo.

SYNOPSIS

	 use Alzabo::Exceptions;

DESCRIPTION

       Using this class creates all the exceptions classes used by Alzabo (via the "Exception::Class" class).

       See "Exception::Class" for more information on how this is done.

EXCEPTION CLASSES

       * Alzabo::Exception
	   This is the base class for all exceptions generated within Alzabo (all exceptions should return true for "$@->isa('Alzabo::Exception')"
	   except those that are generated via internal Perl errors).

       * Alzabo::Exception::Driver
	   An error occured while accessing a database.  See "Alzabo::Driver" for more details.

       * Alzabo::Exception::Eval
	   An attempt to eval something returned an error.

       * Alzabo::Exception::Logic
	   Alzabo was asked to do something logically impossible, like retrieve rows for a table without a primary key.

       * Alzabo::Exception::NoSuchRow
	   An attempt was made to fetch data from the database with a primary key that does not actually exist in the specified table.

       * Alzabo::Exception::NotNullable
	   An attempt was made to set a non-nullable column to "NULL".	The "column_name", "table_name", and "schema_name" fields can be used to
	   identify the exact column.

       * Alzabo::Exception::Panic
	   This exception is thrown when something completely unexpected happens (think Monty Python).

       * Alzabo::Exception::Params
	   This exception is thrown when there is a problem with the parameters passed to a method or function.  These problems can include miss-
	   ing parameters, invalid values, etc.

       * Alzabo::Exception::RDBMSRules
	   A rule for the relevant RDBMS was violated (bad schema name, table name, column attribute, etc.)

       * Alzabo::Exception::ReferentialIntegrity
	   An insert/update/delete was attempted that would violate referential integrity constraints.

       * Alzabo::Exception::SQL
	   An error thrown when there is an attempt to generate invalid SQL via the Alzabo::SQLMaker module.

       * Alzabo::Exception::Storable
	   A error when trying to freeze, thaw, or clone an object using Storable.

       * Alzabo::Exception::System
	   Some sort of system call (file read/write, stat, etc.) failed.

       * Alzabo::Exception::VirtualMethod
	   A virtual method was called.  This indicates that this method should be subclassed.
