Class::WhiteHole adpO Blocks autoloader inheritance MSCHWERN
So, this module might be a little silly, but I had a need. This does
the reverse of Class::BlackHole, all unhandled methods become normal
errors as if no autoloader existed. Useful if you've accidentally
inherited an autoloader and its making your class's error messages
look funny. Class::DBI and Ima::DBI have such a problem.
This is obviously a module that has to be used with care. The docs
cover the issues a bit.
NAME
Class::WhiteHole - base class to treat unhandled method
calls as errors
SYNOPSIS
package Bar;
# DBI inherits from DynaLoader which inherits from AutoLoader
# Bar wants to avoid this accidental inheritance of AutoLoader.
use base qw(Class::WhiteHole DBI);
DESCRIPTION
Its possible to accidentally inherit an AUTOLOAD method.
Often this will happen if a class somewhere in the chain
uses AutoLoader or defines one of their own. This can
lead to confusing error messages when method lookups fail.
Sometimes you want to avoid this accidental inheritance.
In that case, inherit from Class::WhiteHole. All
unhandled methods will produce normal Perl error messages.
CAVEATS
Be sure to have Class::WhiteHole before the class from
which you're inheriting AUTOLOAD in the ISA. Usually
you'll want Class::WhiteHole to come first.
If your class inherits autoloaded routines this class may
cause them to stop working. Choose wisely before using.
