NAME

6       Moose::Meta::TypeCoercion - The Moose Type Coercion metaclass
7

VERSION

9       version 2.2206
10

DESCRIPTION

12       A type coercion object is basically a mapping of one or more type
13       constraints and the associated coercions subroutines.
14
15       It's unlikely that you will need to instantiate an object of this class
16       directly, as it's part of the deep internals of Moose.
17

METHODS

19   Moose::Meta::TypeCoercion->new(%options)
20       Creates a new type coercion object, based on the options provided.
21
22       •   type_constraint
23
24           This is the Moose::Meta::TypeConstraint object for the type that is
25           being coerced to.
26
27   $coercion->type_coercion_map
28       This returns the map of type constraints to coercions as an array
29       reference. The values of the array alternate between type names and
30       subroutine references which implement the coercion.
31
32       The value is an array reference because coercions are tried in the
33       order they are added.
34
35   $coercion->type_constraint
36       This returns the Moose::Meta::TypeConstraint that was passed to the
37       constructor.
38
39   $coercion->has_coercion_for_type($type_name)
40       Returns true if the coercion can coerce the named type.
41
42   $coercion->add_type_coercions( $type_name => $sub, ... )
43       This method takes a list of type names and subroutine references. If
44       the coercion already has a mapping for a given type, it throws an
45       exception.
46
47       Coercions are actually
48
49   $coercion->coerce($value)
50       This method takes a value and applies the first valid coercion it
51       finds.
52
53       This means that if the value could belong to more than type in the
54       coercion object, the first coercion added is used.
55
56   Moose::Meta::TypeCoercion->meta
57       This will return a Class::MOP::Class instance for this class.
