JSON::Any
Wrapper Class for the various JSON classes.

JSON::Any - Wrapper Class for the various JSON classes.


NAME

JSON::Any - Wrapper Class for the various JSON classes.


VERSION

Version 1.13


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 

        JSON::Syck

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 Syck 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.


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.

The actual output will vary, for example JSON will encode and decode unicode chars (the resulting JSON is not unicode) wheras the JSON::XS manpage 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.

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. 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.
