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

VERSION
       version 2.1213

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.
