13
14 sigil
15 The effective sigil ('$', '@' or '%') of this parameter.
16
17 type_constraints
18 Type: Parse::Method::Signatures::TypeConstraint
19
20 Predicate: has_type_constraints
21
22 Representation of the type constraint for this parameter. Most commonly
23 you will just call "meta_type_constraint" and not access this attribute
24 directly.
25
26 default_value
27 Type: Str
28
29 Predicate: has_default_value
30
31 A string that should be eval'd or injected to get the default value for
32 this parameter. For example:
33
34 $name = 'bar'
35
36 Would give a default_value of "'bar'".

38 constraints
39 Type: ArrayRef[Str]
40
41 Predicate: has_constraints
42
43 "where" constraints for this type. Each member of the array a the
44 string (including enclosing braces) of the where constraint block.
45
46 param_traits
47 Type: ArrayRef[ Tupple[Str,Str] ]
48
49 Predicate: has_traits
50
51 Traits that this parameter is declared to have. For instance
52
53 $foo does coerce
54
55 would have a trait of
56
57 ['does', 'coerce']
58
60 to_string
61 meta_type_constraint
62 Get the Moose::Meta::TypeConstraint for this parameter. Check first
63 that the type has a type constraint:
64
65 $tc = $param->meta_type_constraint if $param->has_type_constraints;
