SYNOPSIS

  package MyObject;
  use Class::MakeMethods::Attribute 'Standard::Hash';

  sub new    :MakeMethod('new');
  sub foo    :MakeMethod('scalar');
  sub bar    :MakeMethod('scalar', { hashkey => 'bar_data' });
  sub debug  :MakeMethod('Standard::Global:scalar');

DESCRIPTION

This package allows common types of methods to be generated via a subroutine attribute declaration. (Available in Perl 5.6 and later.)

Adding the :MakeMethod() attribute to a subroutine declaration causes Class::MakeMethods to create and install a subroutine based on the parameters given to the :MakeMethod attribute.

You can declare a default method-generation class by passing the name of a MakeMethods subclass in the use Class::MakeMethods::Attribute statement. This default method-generation class will also apply as the default to any subclasses declared at compile time. If no default method-generation class is selected, you will need to fully-qualify all method type declarations.

EXAMPLE

Here's a typical use of Class::MakeMethods::Attribute:

package MyObject; use Class::MakeMethods::Attribute 'Standard::Hash';

sub new :MakeMethod('new'); sub foo :MakeMethod('scalar'); sub bar :MakeMethod('scalar', { hashkey => 'bar_data' }); sub debug :MakeMethod('Standard::Global:scalar');

package MySubclass; use base 'MyObject';

sub bazzle :MakeMethod('scalar');

This is equivalent to the following explicit Class::MakeMethods invocations:

package MyObject;

use Class::MakeMethods ( -MakerClass => 'Standard::Hash', new => 'new', scalar => 'foo', scalar => [ 'ba', { hashkey => 'bar_data' } ], 'Standard::Global:scalar' => 'debug', );

package MySubclass; use base 'MyObject';

use Class::MakeMethods ( -MakerClass => 'Standard::Hash', scalar => 'bazzle', );

DIAGNOSTICS

The following warnings and errors may be produced when using Class::MakeMethods::Attribute to generate methods. (Note that this list does not include run-time messages produced by calling the generated methods, or the standard messages produced by Class::MakeMethods.) You can not use the \*(C`:MakeMethod\*(C' attribute with lexical or anonymous subroutine declarations.

No method type provided for MakeMethod attribute.

You called \*(C`:MakeMethod()\*(C' without the required method-type argument.
