NAME

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

VERSION

       version 2.2009

DESCRIPTION

       A type coercion object is basically a mapping of one or more type constraints and the
       associated coercions subroutines.

       It's unlikely that you will need to instantiate an object of this class directly, as it's
       part of the deep internals of Moose.

METHODS

   Moose::Meta::TypeCoercion->new(%options)
       Creates a new type coercion object, based on the options provided.

       •   type_constraint

           This is the Moose::Meta::TypeConstraint object for the type that is being coerced to.

   $coercion->type_coercion_map
       This returns the map of type constraints to coercions as an array reference. The values of
       the array alternate between type names and subroutine references which implement the
       coercion.

       The value is an array reference because coercions are tried in the order they are added.

   $coercion->type_constraint
       This returns the Moose::Meta::TypeConstraint that was passed to the constructor.

   $coercion->has_coercion_for_type($type_name)
       Returns true if the coercion can coerce the named type.

   $coercion->add_type_coercions( $type_name => $sub, ... )
       This method takes a list of type names and subroutine references. If the coercion already
       has a mapping for a given type, it throws an exception.

       Coercions are actually

   $coercion->coerce($value)
       This method takes a value and applies the first valid coercion it finds.

       This means that if the value could belong to more than type in the coercion object, the
       first coercion added is used.

   Moose::Meta::TypeCoercion->meta
       This will return a Class::MOP::Class instance for this class.
