NAME

       Class::MakeMethods::Template::Scalar - Methods for blessed scalars

SYNOPSIS

	 package MyObject;
	 use Class::MakeMethods::Template::ExternalData (
	   new		   => 'new',
	   scalar	   => 'foo',
	 );

	 package main;

	 my $obj = MyObject->new( foo => "Foozle" );
	 print $obj->foo();	       # Prints Foozle
	 $obj->foo("Bamboozle");       # Sets $$obj
	 print $obj->foo();	       # Prints Bamboozle

DESCRIPTION

       Supports the Generic object constructor and accessors meta-method types, but uses scalar refs as the underlying implementation type, so
       only one accessor method can be used effectively.

   Standard Methods
       The following methods from Generic are all supported:

	 new
	 scalar
	 string
	 string_index
	 number
	 boolean
	 bits
	 array
	 hash
	 tiedhash
	 hash_of_arrays
	 object
	 instance
	 array_of_objects
	 code
	 code_or_scalar

       See Class::MakeMethods::Template::Generic for the interfaces and behaviors of these method types.

       However, note that due to special nature of this package, all accessor methods reference the same scalar value, so setting a value with one
       method will overwrite the value retrieved by another.

NAME

       Class::MakeMethods::Template::Hash - Method interfaces for hash-based objects

SYNOPSIS

	 package MyObject;
	 use Class::MakeMethods::Template::Hash (
	   new		   => [ 'new' ],
	   scalar	   => [ 'foo', 'bar' ]
	 );

	 package main;

	 my $obj = MyObject->new( foo => "Foozle", bar => "Bozzle" );
	 print $obj->foo();
	 $obj->bar("Bamboozle");

DESCRIPTION

       These meta-methods create and access values within blessed hash objects.

       Common Parameters: The following parameters are defined for Hash meta-methods.

       hash_key
	   The hash key to use when retrieving values from each hash instance. Defaults to '*', the name of the meta-method.

	   Changing this allows you to change an accessor method name to something other than the name of the hash key used to retrieve its value.

	   Note that this parameter is not portable to the other implementations, such as Global or InsideOut.

	   You can take advantage of parameter expansion to define methods whose hash key is composed of the defining package's name and the
	   individual method name, such as "$self->{MyObject-foo}":

		 'hash_key' => '*{target_class}-*{name}'

       Common Behaviors

       Behavior: delete
	   Deletes the named key and associated value from the current hash instance.

   Standard Methods
       The following methods from Generic are all supported:

	 new
	 scalar
	 string
	 string_index
	 number
	 boolean
	 bits (*)
	 array
	 hash
	 tiedhash
	 hash_of_arrays
	 object
	 instance
	 array_of_objects
	 code
	 code_or_scalar

       See Class::MakeMethods::Template::Generic for the interfaces and behaviors of these method types.

       The items marked with a * above are specifically defined in this package, whereas the others are formed automatically by the interaction of
       this package's generic settings with the code templates provided by the Generic superclass.

   struct
	 struct => [ qw / foo bar baz / ];

       Creates methods for setting, checking and clearing values which are stored by position in an array. All the slots created with this meta-
       method are stored in a single array.

       The argument to struct should be a string or a reference to an array of strings. For each string meta-method x, it defines two methods: x
       and clear_x. x returns the value of the x-slot.	If called with an argument, it first sets the x-slot to the argument.  clear_x sets the
       slot to undef.

       Additionally, struct defines three class method: struct, which returns a list of all of the struct values, struct_fields, which returns a
       list of all the slots by name, and struct_dump, which returns a hash of the slot-name/slot-value pairs.
