JSON::Any(3pm) User Contributed Perl Documentation JSON::Any(3pm)
NAME
JSON::Any - Wrapper Class for the various JSON classes.
VERSION
Version 1.22
SYNOPSIS
This module will provide a coherent API to bring together the various JSON modules
currently on CPAN. This module will allow you to code to any JSON API and have it work
regardless of which JSON module is actually installed.
use JSON::Any;
my $j = JSON::Any->new;
$json = $j->objToJson({foo=>'bar', baz=>'quux'});
$obj = $j->jsonToObj($json);
or
$json = $j->encode({foo=>'bar', baz=>'quux'});
$obj = $j->decode($json);
or
$json = $j->Dump({foo=>'bar', baz=>'quux'});
$obj = $j->Load($json);
or
$json = $j->to_json({foo=>'bar', baz=>'quux'});
$obj = $j->from_json($json);
or without creating an object:
$json = JSON::Any->objToJson({foo=>'bar', baz=>'quux'});
$obj = JSON::Any->jsonToObj($json);
On load, JSON::Any will find a valid JSON module in your @INC by looking for them in this
order:
JSON::XS
JSON
JSON::DWIW
And loading the first one it finds.
You may change the order by specifying it on the "use JSON::Any" line:
use JSON::Any qw(DWIW XS JSON);
Specifying an order that is missing one of the modules will prevent that module from being
used:
use JSON::Any qw(DWIW XS JSON);
This will check in that order, and will never attempt to load JSON::Syck. This can also be
set via the $ENV{JSON_ANY_ORDER} environment variable.
JSON::Syck has been deprecated by it's author, but in the attempt to still stay relevant
as a "Compat Layer" JSON::Any still supports it. This support however has been made
optional starting with JSON::Any 1.19. In deference to a bug request starting with JSON
1.20 JSON::Syck and other deprecated modules will still be installed, but only as a last
resort and will now include a warning.
use JSON::Any qw(Syck XS JSON);
or
$ENV{JSON_ANY_ORDER} = 'Syck XS JSON';
WARNING: If you call JSON::Any with an empty list
use JSON::Any ();
It will skip the JSON package detection routines and will die loudly that it couldn't find
a package.
FUNCTIONS
"new"
Will take any of the parameters for the underlying system and pass them through.
However these values don't map between JSON modules, so, from a portability standpoint
this is really only helpful for those paramters that happen to have the same name.
This will be addressed in a future release.
The one parameter that is universally supported (to the extent that is supported by
the underlying JSON modules) is "utf8". When this parameter is enabled all resulting
JSON will be marked as unicode, and all unicode strings in the input data structure
will be preserved as such.
Also note that the "allow_blessed" parameter is recognised by all the modules that
throw exceptions when a blessed reference is given them meaning that setting it to
true works for all modules. Of course, that means that you cannot set it to false
intentionally in order to always get such exceptions.
The actual output will vary, for example JSON will encode and decode unicode chars
(the resulting JSON is not unicode) wheras JSON::XS will emit unicode JSON.
"handlerType"
Takes no arguments, returns a string indicating which JSON Module is in use.
"handler"
Takes no arguments, if called on an object returns the internal JSON::* object in use.
Otherwise returns the JSON::* package we are using for class methods.
"true"
Takes no arguments, returns the special value that the internal JSON object uses to
map to a JSON "true" boolean.
"false"
Takes no arguments, returns the special value that the internal JSON object uses to
map to a JSON "false" boolean.
"objToJson"
Takes a single argument, a hashref to be converted into JSON. It returns the JSON
text in a scalar.
"to_json"
"Dump"
"encode"
Aliases for objToJson, can be used interchangeably, regardless of the underlying JSON
module.
"jsonToObj"
Takes a single argument, a string of JSON text to be converted back into a hashref.
"from_json"
"Load"
"decode"
Aliases for jsonToObj, can be used interchangeably, regardless of the underlying JSON
module.

BUGS
Please report any bugs or feature requests to "bug-json-any at rt.cpan.org", or through
the web interface at <http://rt.cpan.org/NoAuth/ReportBug.html?Queue=JSON-Any>. I will be
notified, and then you'll automatically be notified of progress on your bug as I make
changes.
ACKNOWLEDGEMENTS
This module came about after discussions on irc.perl.org about the fact that there were
now six separate JSON perl modules with different interfaces.
In the spirit of Class::Any, JSON::Any was created with the considerable help of Matt
'mst' Trout.
Simon Wistow graciously supplied a patch for backwards compat with JSON::XS versions
previous to 2.01
