NAME

6       MooseX::Meta::TypeConstraint::Structured - Structured type constraints
7

VERSION

9       version 0.36

DESCRIPTION

12       A structure is a set of Moose::Meta::TypeConstraint that are
13       'aggregated' in such a way as that they are all applied to an incoming
14       list of arguments.  The idea here is that a Type Constraint could be
15       something like, "An "Int" followed by an "Int" and then a "Str"" and
16       that this could be done so with a declaration like:
17
18           Tuple[Int,Int,Str]; ## Example syntax
19
20       So a structure is a list of type constraints (the "Int,Int,Str" in the
21       above example) which are intended to function together.
22

ATTRIBUTES

24   type_constraints
25       A list of Moose::Meta::TypeConstraint objects.
26
27   constraint_generator

METHODS

29   validate
30       Messing with validate so that we can support nicer error messages.
31
32   generate_constraint_for ($type_constraints)
33       Given some type constraints, use them to generate validation rules for
34       an ref of values (to be passed at check time)
35
36   parameterize (@type_constraints)
37       Given a ref of type constraints, create a structured type.
38
39   __infer_constraint_generator
40   compile_type_constraint
41       hook into compile_type_constraint so we can set the correct validation
42       rules.
43
44   create_child_type
45       modifier to make sure we get the constraint_generator
46
47   is_a_type_of
48   is_subtype_of
49   equals
50       Override the base class behavior.
51
52   type_constraints_equals
53       Checks to see if the internal type constraints are equal.
54
55   get_message
56       Give you a better peek into what's causing the error.  For now we
57       stringify the incoming deep value with Devel::PartialDump and pass that
58       on to either your custom error message or the default one.  In the
59       future we'll try to provide a more complete stack trace of the actual
60       offending elements
61
62       A subref or closure that contains the way we validate incoming values
63       against a set of type constraints.
64
65       This returns a CODEREF which generates a suitable constraint generator.
66       Not user servicable, you'll never call this directly.
