DESCRIPTION

"TAP::Object" provides a default constructor and exception model for all "TAP::*" classes. Exceptions are raised using Carp.

METHODS

Class Methods

"new"

Create a new object. Any arguments passed to "new" will be passed on to the ``_initialize'' method. Returns a new object.

Instance Methods

"_initialize"

Initializes 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.

"_croak"

Raise 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' );

"_confess"

Raise 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' );

"_construct"

Create a new instance of the specified class.

"mk_methods"

Create simple getter/setters.
