=head1 NAME

Class::Method::array - Create methods for handling an array value.

=head1 SYNOPSIS

  use Class::MethodMaker
    [ array => [qw/ x /] ];

  $instance->x;                # empty
  $instance->x(1, 1, 2, 3, 5, 8);
  $instance->x_count == 6;     # true
  $instance->x = (13, 21, 34);
  $instance->x_index(1) == 21; # true

=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_clear>, C<x_isset>,
C<x_count>, C<x_index>, C<x_push>, C<x_pop>, C<x_unshift>, C<x_shift>,
C<x_splice>.


Methods available are:

=head3 C<*>

I<Created by default.> This method returns the list of values stored in the
slot.  If any arguments are provided to this method, they B<replace> the
current list contents.  In an array context it returns the values as an array
and in a scalar context as a reference to an array.  Note that this reference
is no longer a direct reference to the storage, in contrast to
Class::MethodMaker v1.  This is to protect encapsulation.  See x_ref if you
need that functionality (and are prepared to take the associated risk.)  This
function no longer auto-expands arrayrefs input as arguments, since that makes
it awkward to set individual values to arrayrefs.  See x_setref for that
functionality.

If a default value is in force, then that value will be auto-vivified (and
therefore set) for each otherwise I<unset> (not I<not defined>) value up to
the array max (so new items will not be appended)


=head3 C<*_reset>

I<Created by default.> Called without an argument, this resets the component
as a whole; deleting any associated storage, and returning the component to
its default state.  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.

If called with arguments, these arguments are treated as indexes into the
component, and the individual elements thus referenced are reset (their
storage deleted, so that C<*_isset(n)> will return false for appropriate I<n>,
except where C<-default> or C<-default_ctor> are in force, as above).  As with
perl arrays, resetting the highest set value implicitly decreases the count
(but x_reset(n) never unsets the aggregate itself, even if all the elements
are not set).


=head3 C<*_clear>

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

  package main;
  my $m = MyClass->new;
  $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 on request>.  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<*_isset>

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.

C<*_isset()> tests the component as a whole.  C<*_isset(a)> tests the element
indexed by I<a>.  C<*_isset(a,b)> tests the elements indexed by I<a>, I<b>,
and returns the logical conjunction (I<and>) of the tests.


=head3 C<*_count>

I<Created by default.> Returns the number of elements in this component.  This
is not affected by presence (or lack) of a C<default> (or C<default_ctor>).
Returns C<undef> if whole component not set (as per C<*_isset>).


=head3 C<*_index>

I<Created by default.> Takes a list of indices, returns a list of the
corresponding values.

If a default (or a default ctor) is in force, then a lookup by
index will vivify & set to the default the respective elements (and
therefore the aggregate data-structure also, if it's not already).

Beware of a bug in perl 5.6.1 that will sometimes invent values in
previously unset slots of arrays that previously contained a value.
So, vivifying a value (e.g. by x_index(2)) where x_index(1) was
previously unset might cause x_index(1) to be set spuriously.  This
is fixed in 5.8.0.


=head3 C<*_push>

I<Created by default.> Push item(s) onto the end of the list.  No return
value.


=head3 C<*_pop>

I<Created by default.> Given a number, pops that many items off the end of the
list, and returns them (as a ref in scalar context, as a list in list
context).  Without an arg, always returns a single element.  Given a number,
returns them in array order (not in reverse order as multiple pops would).


=head3 C<*_unshift>

I<Created by default.> Push item(s) onto the start of the list.  No return
value.


=head3 C<*_shift>

I<Created by default.> Given a number, shifts that many items off the start of
the list, and returns them (as a ref in scalar context, as a list in list
context).  Without an arg, always returns a single element.  Given a number,
returns them in array order.


=head3 C<*_splice>

I<Created by default.> Arguments as for L<perldoc perlfunc splice|splice>.
Returns an arrayref in scalar context (even if a single item is spliced), and
a list in list context.


=head3 C<*_get>

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


=head3 C<*_set>

  @n = $x->a; # (1,2,3)
  $x->a_set(1=>4,3=>7);
  @n = $x->a; # (1,4,3,7)

I<Created by default.> Takes a list, treated as pairs of index => value; each
given index is set to the corresponding value.  No return.

If two arguments are given, of which the first is an arrayref, then it is
treated as a list of indices of which the second argument (which must also be
an arrayref) are the corresponding values.  Thus the following two commands
are equivalent:

  $x->a_set(1=>4,3=>7);
  $x->a_set([1,3],[4,7]);
