NAME

Class::Accessor::Lite::Lazy - Class::Accessor::Lite with lazy accessor feature

SYNOPSIS

  package MyPackage;

  use Class::Accessor::Lite::Lazy (
      rw_lazy => [
        # implicit builder method name is "_build_foo"
        qw(foo foo2),
        # or specify builder explicitly
        {
          xxx => 'method_name',
          yyy => sub {
            my $self = shift;
            ...
          },
        }
      ],
      ro_lazy => [ qw(bar) ],
      # Class::Accessor::Lite functionality is also available
      new => 1,
      rw  => [ qw(baz) ],
  );

  # or if you specify all attributes' builders explicitly
  use Class::Accessor::Lite::Lazy (
      rw_lazy => {
        foo => '_build_foo',
        bar => \&_build_bar,
      }
  );

  sub _build_foo {
      my $self = shift;
      ...
  }

  sub _build_bar {
      my $self = shift;
      ...
  }

DESCRIPTION

Class::Accessor::Lite::Lazy provides a "lazy" accessor feature to Class::Accessor::Lite.

If a lazy accessor without any value set is called, a builder method is called to generate a value to set.

THE USE STATEMENT

As Class::Accessor::Lite, the use statement provides the way to create lazy accessors.

rw_lazy => \@name_of_the_properties | \%properties_and_builders

Creates read / write lazy accessors.

ro_lazy => \@name_of_the_properties | \%properties_and_builders

Creates read-only lazy accessors.

new, rw, ro, wo

Same as Class::Accessor::Lite.

FUNCTIONS

Class::Accessor::Lite::Lazy->mk_lazy_accessors(@name_of_the_properties)

Creates lazy accessors in current package.

Class::Accessor::Lite::Lazy->mk_ro_lazy_accessors(@name_of_the_properties)

Creates read-only lazy accessors in current package.

SPECIFYING BUILDERS

As seen in SYNOPSIS, each attribute is specified by either a string or a hashref.

In the string form $attr you specify builders implicitly, the builder method name for the attribute $attr is named _build_$attr.

In the hashref form { $attr => $method_name | \&builder } you can explicitly specify builders, each key is the attribute name and each value is either a string which specifies the builder method name or a coderef itself.
