MakeMethods::Template:UseriContributed PerlMakeMethods::Template::InsideOut(3)NAMEClass::MakeMethods::Template::InsideOut - External data
SYNOPSIS
package MyObject;
use Class::MakeMethods::Template::InsideOut (
scalar => [ 'foo', 'bar' ]
);
sub new { ... }
package main;
my $obj = MyObject->new( foo => "Foozle", bar => "Bozzle" );
print $obj->foo(); # Prints Foozle
$obj->bar("Bamboozle"); # Sets $obj's bar value
DESCRIPTION
Supports the Generic object constructor and accessors meta-method
types, but accepts any object as the underlying implementation type,
with member data stored in external indices.
Each method stores the values associated with various objects in an
hash keyed by the object's stringified identity. Since that hash is
accessible only from the generated closures, it is impossible for
foreign code to manipulate those values except through the method
interface.
A DESTROY method is installed to remove data for expired objects from
the various hashes. (If the DESTROY method is not called, your program
will not release this data and memory will be wasted.)
Common Parameters: The following parameters are defined for InsideOut
meta-methods.
data
An auto-vivified reference to a hash to be used to store the values
for each object.
Note that using InsideOut meta-methods causes the installation of a
DESTROY method in the calling class, which deallocates data for each
instance when it is discarded.
NOTE: This needs some more work to properly handle inheritance.
Standard Methods
The following methods from Generic are all supported:
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.
boolean_index
boolean_index => [ qw / foo bar baz / ]
Like InsideOut:boolean, boolean_index creates x, set_x, and clear_x
methods. However, it also defines a class method find_x which returns a
list of the objects which presently have the x-flag set to true.
Note that to free items from memory, you must clear these bits!
