Moose::Meta::TypeCoercion - phpMan

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

VERSION
    version 2.2200

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.
