NAME

       Type::Tiny::Class - type constraints based on the "isa" method

DESCRIPTION

       Type constraints of the general form "{ $_->isa("Some::Class") }".

       This package inherits from Type::Tiny; see that for most documentation.  Major differences
       are listed below:

   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 should generally not pass a constraint to the constructor.
           Instead rely on the default.

       "inlined"
           Unlike Type::Tiny, you should generally not 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(Types::Standard::HashRef, "new")
              $classtype->plus_constructors()  ## identical to above

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