Constructor

"new"

When the constructor is called on an instance of Type::Tiny::Class, it passes the call through to the constructor of the class for the constraint. So for example:

   my $type = Type::Tiny::Class->new(class => "Foo::Bar");
   my $obj  = $type->new(hello => "World");
   say ref($obj);   # prints "Foo::Bar"
    

This little bit of DWIM was borrowed from MooseX::Types::TypeDecorator, but Type::Tiny doesn't take the idea quite as far.

Attributes

"class"

The class for the constraint.

"constraint"

Unlike Type::Tiny, you cannot pass a constraint coderef to the constructor. Instead rely on the default.

"inlined"

Unlike Type::Tiny, you cannot pass an inlining coderef to the constructor. Instead rely on the default.

"parent"

Parent is automatically calculated, and cannot be passed to the constructor.

Methods

"plus_constructors($source, $method_name)"

Much like "plus_coercions" but adds coercions that go via a constructor. (In fact, this is implemented as a wrapper for "plus_coercions".)

Example:

   package MyApp::Minion;
   
   use Moose; extends "MyApp::Person";
   
   use Types::Standard qw( HashRef Str );
   use Type::Utils qw( class_type );
   
   my $Person = class_type({ class => "MyApp::Person" });
   
   has boss => (
      is     => "ro",
      isa    => $Person->plus_constructors(
         HashRef,     "new",
         Str,         "_new_from_name",
      ),
      coerce => 1,
   );
   
   package main;
   
   MyApp::Minion->new(
      ...,
      boss => "Bob",  ## via MyApp::Person->_new_from_name
   );
   
   MyApp::Minion->new(
      ...,
      boss => { name => "Bob" },  ## via MyApp::Person->new
   );
    

Because coercing "HashRef" via constructor is a common desire, if you call "plus_constructors" with no arguments at all, this is the default.

   $classtype->plus_constructors(HashRef, "new")
   $classtype->plus_constructors()  ## identical to above
    

This is handy for Moose/Mouse/Moo-based classes.

Exports

Type::Tiny::Class can be used as an exporter.

  use Type::Tiny::Class 'HTTP::Tiny';

This will export the following functions into your namespace:

"HTTPTiny"

"is_HTTPTiny( $value )"

"assert_HTTPTiny( $value )"

"to_HTTPTiny( $value )"

You will also be able to use "HTTPTiny->new(...)" as a shortcut for "HTTP::Tiny->new(...)".

Multiple types can be exported at once:

  use Type::Tiny::Class qw( HTTP::Tiny LWP::UserAgent );
