perl-Class-ErrorHandler

Class::ErrorHandler provides an error-handling mechanism that's generic
enough to be used as the base class for a variety of OO classes. Subclasses
inherit its two error-handling methods, error and errstr, to
communicate error messages back to the calling program.
On failure (for whatever reason), a subclass should call error and return
to the caller; error itself sets the error message internally, then
returns 'undef'. This has the effect of the method that failed returning
'undef' to the caller. The caller should check for errors by checking for a
return value of 'undef', and calling errstr to get the value of the error
message on an error.
As demonstrated in the the SYNOPSIS manpage, error and errstr work as
both class methods and object methods.
