SYNOPSIS

  my $arrayref = t('ArrayRef');

  my $arrayref_of_int = $arrayref->parameterize( of => t('Int') );

  my $parameter = $arrayref_of_int->parameter(); # returns Int

DESCRIPTION

This class implements the API for parameterized types.

API

This class implements the same API as Type::Constraint::Simple, with a few additions.

Type::Constraint::Parameterized->new(...)

This class's constructor accepts two additional parameters:

• parent

  This should be the Type::Constraint::Parameterizable object from which this object was created.

  This parameter is required.

• parameter

  This is the type parameter for the parameterized type. This must be an object which does the Type::Constraint::Role::Interface role.

  This parameter is required.

$type->parameter()

Returns the type that was passed to the constructor.
