Moose::Meta::TypeCoercion - The Moose Type Coercion metaclass
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.
Creates a new type coercion object, based on the options provided.
This is the Moose::Meta::TypeConstraint object for the type that is being coerced to.
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.
This returns the Moose::Meta::TypeConstraint that was passed to the constructor.
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
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.
This will return a Class::MOP::Class instance for this class.
All complex software has bugs lurking in it, and this module is no exception. If you find a bug please either email me, or add the bug to cpan-RT.
