=head1 NAME

Class::Method::scalar - Create methods for handling a scalar value.

=head1 SYNOPSIS

  package MyClass;
  use Class::MethodMaker
    [ scalar => [qw/ a -static s /]];

  sub new {
    my $class = shift;
    bless {}, $class;
  }

  package main;

  my $m = MyClass->new;
  my $a, $x;

  $a = $m->a;       # *undef*
  $x = $m->a_isset; # false
  $a = $m->a(1);    # 1
  $m->a(3);
  $x = $m->a_isset; # true
  $a = $m->a;       # 3
  $a = $m->a(5);     # 5;
  $m->a_reset;
  $x = $m->a_isset; # false

=head1 DESCRIPTION

Creates methods to handle array values in an object.  For a component named
C<x>, by default creates methods C<x>, C<x_reset>, C<x_isset>, C<x_clear>.


Methods available are:


=head3 C<*>

  $m->a(3);
  $a = $m->a;       # 3
  $a = $m->a(5);     # 5;

I<Created by default>.  If an argument is provided, the component is set to
that value.  The method returns the value of the component (after assignment
to a provided value, if appropriate).


=head3 C<*_reset>

  $m->a_reset;

I<Created by default>.  Resets the component back to its default.  Normally,
this means that C<*_isset> will return false, and C<*> will return undef.  If
C<-default> is in effect, then the component will be set to the default value,
and C<*_isset> will return true.  If C<-default_ctor> is in effect, then the
default subr will be invoked, and its return value used to set the value of
the component, and C<*_isset> will return true.

B<Advanced Note>: actually, defaults are assigned as needed: typically, the
next time a the value of a component is read.


=head3 C<*_isset>

  print $m->a_isset ? "true" : "false";

I<Created by default>.  Whether the component is currently set.  This is
different from being defined; initially, the component is not set (and if
read, will return undef); it can be set to undef (which is a set value, which
also returns undef).  Having been set, the only way to unset the component is
with <*_reset>.

If a default value is in effect, then <*_isset> will always return true.


=head3 C<*_clear>

  $m->a(5);
  $a = $m->a;       # 5
  $x = $m->a_isset; # true
  $m->a_clear;
  $a = $m->a;       # *undef*
  $x = $m->a_isset; # true

I<Created by default>.  A shorthand for setting to undef.  Note that the
component will be set to undef, not reset, so C<*_isset> will return true.


=head3 C<*_get>

  package MyClass;
  use Class::MethodMaker
    [ scalar => [{'*_get' => '*_get'}, 'a'],
      new    => new, ];

  package main;
  my $m = MyClass->new;
  $m->a(3);
  $a = $m->a_get;     # 3
  $a = $m->a_get(5);  # 3; ignores argument
  $a = $m->a_get(5);  # 3; unchanged by previous call

I<Created on request>.  Retrieves the value of the component without setting
(ignores any arguments passed).


=head3 C<*_set>

  package MyClass;
  use Class::MethodMaker
    [ scalar => [{'*_set' => '*_set'}, 'a'],
      new    => new, ];

  package main;
  my $m = MyClass->new;
  $m->a(3);
  $a = $m->a_set;     # *undef*
  $a = $m->a_set(5);  # *undef*; value is set but not returned
  $a = $m->a;         # 5

I<Created on request>.  Sets the component to the first argument (or undef if
no argument provided).  Returns no value.
