# Specio::Constraint::Parameterized(3pm)

A class which represents parameterized constraints

## NAME

Specio::Constraint::Parameterized - A class which represents parameterized constraints

## VERSION

version 0.53

## SYNOPSIS

```
    my $arrayref = t('ArrayRef');
    my $arrayref_of_int = $arrayref->parameterize( of => t('Int') );
    my $parent = $arrayref_of_int->parent; # returns ArrayRef
    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 Specio::Constraint::Simple, with a few additions.

### Specio::Constraint::Parameterized-\>new(...)

This class's constructor accepts two additional parameters:

- •

  parent

  This should be the Specio::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 Specio::Constraint::Role::Interface role.

  This parameter is required.

### $type-\>parameter

Returns the type that was passed to the constructor.
