  package MyApp::Error;

  has execution_phase => (
    is  => 'ro',
    isa => 'MyApp::Phase',
    default => 'startup',

  });

DESCRIPTION

Throwable::Error is a base class for exceptions that will be thrown to signal errors and abort normal program flow. Throwable::Error is an alternative to Exception::Class, the features of which are largely provided by the Moose object system atop which Throwable::Error is built.

Throwable::Error performs the Throwable and StackTrace::Auto roles. That means you can call throw on it to create and throw an error object in one call, and that every error object will have a stack trace for its creation.

ATTRIBUTES

message

This attribute must be defined and must contain a string describing the error condition. This string will be printed at the top of the stack trace when the error is stringified.

stack_trace

This attribute, provided by StackTrace::Auto, will contain a stack trace object guaranteed to respond to the as_string method. For more information about the stack trace and associated behavior, consult the StackTrace::Auto docs.

METHODS

as_string

This method will provide a string representing the error, containing the error's message followed by the its stack trace.
