NAME

6       Specio::DeclaredAt - A class to represent where a type or coercion was
7       declared
8

VERSION

10       version 0.46
11

SYNOPSIS

13           my $declared = Specio::DeclaredAt->new_from_caller(1);
14
15           print $declared->description;
16

DESCRIPTION

18       This class provides a thin wrapper around some of the return values
19       from Perl's "caller" built-in. It's used internally to identify where
20       types and coercions are being declared, which is useful when generating
21       error messages.
22

API

24       This class provides the following methods.
25
26   Specio::DeclaredAt->new_from_caller($depth)
27       Given a call stack depth, this method returns a new
28       "Specio::DeclaredAt" object.
29
30   $declared_at->package, $declared_at->filename, $declared_at->line
31       Returns the call stack information recorded when the object was
32       created. These values are always populated.
33
34   $declared_at->subroutine
35       Returns the subroutine from the call stack. This may be an "udnef"
36
37   $declared_at->has_subroutine
38       Returns true if there is a subroutine name associated with this object.
39
40   $declared_at->description
41       Puts all the information together into a single string like "declared
42       in package Foo::Bar (.../Foo/Bar.pm) at line 42 in sub named blah".
