.SH DESCRIPTION
.IX Header "DESCRIPTION"
This class contains attributes which are common to all Moose internal
exception classes.
.SH "WARNING WARNING WARNING"
.IX Header "WARNING WARNING WARNING"
If you\*(Aqre writing your own exception classes, you should instead prefer
the Throwable role or the Throwable::Error superclass \- this is
effectively a cut\-down internal fork of the latter, and not designed
for use in user code.
.PP
Of course if you\*(Aqre writing metaclass traits, it would then make sense to
subclass the relevant Moose exceptions \- but only then.
.SH METHODS
.IX Header "METHODS"
.ie n .SS $exception\->message
.el .SS \f(CW$exception\fP\->message
.IX Subsection "$exception->message"
This attribute contains the exception message.
.PP
Every subclass of Moose::Exception is expected to override
\&\f(CW\*(C`_build_message\*(C'\fR method in order to construct this value.
.ie n .SS $exception\->trace
.el .SS \f(CW$exception\fP\->trace
.IX Subsection "$exception->trace"
This attribute contains the stack trace for the given exception. It returns a
Devel::StackTrace object.
.ie n .SS $exception\->as_string
.el .SS \f(CW$exception\fP\->as_string
.IX Subsection "$exception->as_string"
This method returns a stringified form of the exception, including a stack
trace. By default, this method skips Moose\-internal stack frames until it sees
a caller outside of the Moose core. If the \f(CW\*(C`MOOSE_FULL_EXCEPTION\*(C'\fR environment
variable is true, these frames are included.
