NAME

6       Throwable::Error - an easy-to-use class for error objects
7

VERSION

9       version 1.001
10

SYNOPSIS

12         package MyApp::Error;
13         # NOTE: Moo can also be used here instead of Moose
14         use Moose;
15         extends 'Throwable::Error';
16
17         has execution_phase => (
18           is  => 'ro',
19           isa => 'MyApp::Phase',
20           default => 'startup',
21         );
22
23       ...and in your app...
24
25         MyApp::Error->throw("all communications offline");
26
27         # or...
28
29         MyApp::Error->throw({
30           message         => "all communications offline",
31           execution_phase => 'shutdown',
32         });

DESCRIPTION

35       Throwable::Error is a base class for exceptions that will be thrown to
36       signal errors and abort normal program flow.  Throwable::Error is an
37       alternative to Exception::Class, the features of which are largely
38       provided by the Moo object system atop which Throwable::Error is built.
39
40       Throwable::Error performs the Throwable and StackTrace::Auto roles.
41       That means you can call "throw" on it to create and throw an error
42       object in one call, and that every error object will have a stack trace
43       for its creation.
44

PERL VERSION

46       This library should run on perls released even a long time ago.  It
47       should work on any version of perl released in the last five years.
48
49       Although it may work on older versions of perl, no guarantee is made
50       that the minimum required version will not be increased.  The version
51       may be increased for any reason, and there is no promise that patches
52       will be accepted to lower the minimum required perl.
53

ATTRIBUTES

55   message
56       This attribute must be defined and must contain a string describing the
57       error condition.  This string will be printed at the top of the stack
58       trace when the error is stringified.
59
60   stack_trace
61       This attribute, provided by StackTrace::Auto, will contain a stack
62       trace object guaranteed to respond to the "as_string" method.  For more
63       information about the stack trace and associated behavior, consult the
64       StackTrace::Auto docs.
65

METHODS

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