Version 3.23

TAP::Object provides a default constructor and exception model for all
TAP::* classes. Exceptions are raised using Carp.
newCreate a new object. Any arguments passed to new will be passed on to the
_initialize method. Returns a new object.
_initializeInitializes a new object. This method is a stub by default, you should override it as appropriate.
Note: new expects you to return $self or raise an exception. See
_croak, and Carp.
_croakRaise an exception using croak from Carp, eg:
$self->_croak( 'why me?', 'aaarrgh!' );
May also be called as a class method.
$class->_croak( 'this works too' );
_confessRaise an exception using confess from Carp, eg:
$self->_confess( 'why me?', 'aaarrgh!' );
May also be called as a class method.
$class->_confess( 'this works too' );
_constructCreate a new instance of the specified class.
mk_methodsCreate simple getter/setters.
