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.
