.SH DESCRIPTION
.IX Header "DESCRIPTION"
\&\f(CW\*(C`TAP::Object\*(C'\fR provides a default constructor and exception model for all
\&\f(CW\*(C`TAP::*\*(C'\fR classes.  Exceptions are raised using Carp.
.SH METHODS
.IX Header "METHODS"
.SS "Class Methods"
.IX Subsection "Class Methods"
\fR\f(CI\*(C`new\*(C'\fR\fI\fR
.IX Subsection "new"
.PP
Create a new object.  Any arguments passed to \f(CW\*(C`new\*(C'\fR will be passed on to the
"_initialize" method.  Returns a new object.
.SS "Instance Methods"
.IX Subsection "Instance Methods"
\fR\f(CI\*(C`_initialize\*(C'\fR\fI\fR
.IX Subsection "_initialize"
.PP
Initializes a new object.  This method is a stub by default, you should override
it as appropriate.
.PP
\&\fINote:\fR "new" expects you to return \f(CW$self\fR or raise an exception.  See
"_croak", and Carp.
.PP
\fR\f(CI\*(C`_croak\*(C'\fR\fI\fR
.IX Subsection "_croak"
.PP
Raise an exception using \f(CW\*(C`croak\*(C'\fR from Carp, eg:
.PP
.Vb 1
\&    $self\->_croak( \*(Aqwhy me?\*(Aq, \*(Aqaaarrgh!\*(Aq );

May also be called as a \fIclass\fR method.
