NAME ^

Class::MakeMethods::Basic::Global - Basic shared methods

SYNOPSIS ^

  package MyObject;
  use Class::MakeMethods::Basic::Global (
    scalar => [ 'foo', 'bar' ],
    array => 'my_list',
    hash => 'my_index',
  );
  ....
  
  # Store and retrieve global values
  MyObject->foo('Foobar');
  print MyObject->foo();
  
  # All instances of your class access the same values
  $my_object->bar('Barbados'); 
  print $other_one->bar(); 
  
  # Array accessor
  MyObject->my_list(0 => 'Foozle', 1 => 'Bang!');
  print MyObject->my_list(1);
  
  # Hash accessor
  MyObject->my_index('broccoli' => 'Blah!', 'foo' => 'Fiddle');
  print MyObject->my_index('foo');

DESCRIPTION ^

The Basic::Global subclass of MakeMethods provides basic accessors for data shared by an entire class, sometimes called "static" or "class data."

Calling Conventions

When you use this package, the method names you provide as arguments cause subroutines to be generated and installed in your module.

See "Calling Conventions" in Class::MakeMethods::Basic for a summary, or "USAGE" in Class::MakeMethods for full details.

Declaration Syntax

To declare methods, pass in pairs of a method-type name followed by one or more method names. Valid method-type names for this package are listed in "METHOD GENERATOR TYPES".

See "Declaration Syntax" in Class::MakeMethods::Basic for more syntax information.

METHOD GENERATOR TYPES ^

scalar - Shared Accessor

For each method name passed, uses a closure to generate a subroutine with the following characteristics:

Sample declaration and usage:

  package MyObject;
  use Class::MakeMethods::Basic::Hash (
    scalar => 'foo',
  );
  ...
  
  # Store value
  MyObject->foo('Foozle');
  
  # Retrieve value
  print MyObject->foo;

array - Shared Ref Accessor

For each method name passed, uses a closure to generate a subroutine with the following characteristics:

Sample declaration and usage:

  package MyObject;
  use Class::MakeMethods::Basic::Hash (
    array => 'bar',
  );
  ...
  
  # Set values by position
  $obj->bar(0 => 'Foozle', 1 => 'Bang!');
  
  # Positions may be overwritten, and in any order
  $obj->bar(2 => 'And Mash', 1 => 'Blah!');
  
  # Retrieve value by position
  print $obj->bar(1);
  
  # Retrieve slice of values by position
  print join(', ', $obj->bar( [0, 2] ) );
  
  # Direct access to referenced array
  print scalar @{ $obj->bar() };
  
  # Reset the array contents to empty
  @{ $obj->bar() } = ();

hash - Shared Ref Accessor

For each method name passed, uses a closure to generate a subroutine with the following characteristics:

Sample declaration and usage:

  package MyObject;
  use Class::MakeMethods::Basic::Hash (
    hash => 'baz',
  );
  ...
  
  # Set values by key
  $obj->baz('foo' => 'Foozle', 'bar' => 'Bang!');
  
  # Values may be overwritten, and in any order
  $obj->baz('broccoli' => 'Blah!', 'foo' => 'Fiddle');
  
  # Retrieve value by key
  print $obj->baz('foo');
  
  # Retrieve slice of values by position
  print join(', ', $obj->baz( ['foo', 'bar'] ) );
  
  # Direct access to referenced hash
  print keys %{ $obj->baz() };
  
  # Reset the hash contents to empty
  @{ $obj->baz() } = ();
