NAME

Specio::Constraint::Structured - A class which represents structured constraints

VERSION

version 0.47

SYNOPSIS

    my $tuple = t('Tuple');

    my $tuple_of_str_int = $tuple->parameterize( of => [ t('Str'), t('Int') ] );

    my $parent = $tuple_of_str_int->parent; # returns Tuple
    my $parameters = $arrayref_of_int->parameters; # returns { of => [ t('Str'), t('Int') ] }

DESCRIPTION

This class implements the API for structured types.

API

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

Specio::Constraint::Structured->new(...)

This class's constructor accepts two additional parameters:

•

parent

This should be the Specio::Constraint::Structurable object from which this object was created.

This parameter is required.

•

parameters

This is the hashref of parameters for the structured type. These are the parameters returned by the "Structurable" type's "parameterization_args_builder". The exact form of this hashref will vary for each structured type.

This parameter is required.

$type->parameters

Returns the hashref that was passed to the constructor.
