.IX Title "JSON::Any 3"
.TH JSON::Any 3 "2007-10-22" "perl v5.8.8" "User Contributed Perl Documentation"
.SH "NAME"
JSON::Any \- Wrapper Class for the various JSON classes.
.SH "VERSION"
.IX Header "VERSION"
Version 1.12
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
This module will provide a coherent \s-1API\s0 to bring together the various \s-1JSON\s0
modules currently on \s-1CPAN\s0. This module will allow you to code to any \s-1JSON\s0 \s-1API\s0
and have it work regardless of which \s-1JSON\s0 module is actually installed.
.PP
.Vb 1
\&        use JSON::Any;
.Ve
.PP
.Vb 1
\&        my $j = JSON::Any->new;
.Ve
.PP
.Vb 2
\&        $json = $j->objToJson({foo=>'bar', baz=>'quux'});
\&        $obj = $j->jsonToObj($json);
.Ve
.PP
or
.PP
.Vb 2
\&        $json = $j->encode({foo=>'bar', baz=>'quux'});
\&        $obj = $j->decode($json);
.Ve
.PP
or
.PP
.Vb 2
\&        $json = $j->Dump({foo=>'bar', baz=>'quux'});
\&        $obj = $j->Load($json);
.Ve
.PP
or
.PP
.Vb 2
\&        $json = $j->to_json({foo=>'bar', baz=>'quux'});
\&        $obj = $j->from_json($json);
.Ve
.PP
or without creating an object:
.PP
.Vb 2
\&        $json = JSON::Any->objToJson({foo=>'bar', baz=>'quux'});
\&        $obj = JSON::Any->jsonToObj($json);
.Ve
.PP
On load, JSON::Any will find a valid \s-1JSON\s0 module in your \f(CW@INC\fR by looking 
for them in this order:
.PP
.Vb 4
\&        JSON::XS 
\&        JSON 
\&        JSON::DWIW 
\&        JSON::Syck
.Ve
.PP
And loading the first one it finds.
.PP
You may change the order by specifying it on the \f(CW\*(C`use JSON::Any\*(C'\fR line:
.PP
.Vb 1
\&        use JSON::Any qw(DWIW Syck XS JSON);
.Ve
.PP
Specifying an order that is missing one of the modules will prevent that module from being used:
.PP
.Vb 1
\&        use JSON::Any qw(DWIW XS JSON);
.Ve
.PP
This will check in that order, and will never attempt to load JSON::Syck. This can also be set via
the \f(CW$ENV\fR{\s-1JSON_ANY_ORDER\s0} environment variable.
.SH "FUNCTIONS"
.IX Header "FUNCTIONS"
.ie n .IP """new""" 4
.el .IP "\f(CWnew\fR" 4
.IX Item "new"
Will take any of the parameters for the underlying system and pass them through. 
However these values don't map between \s-1JSON\s0 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.
.Sp
The one parameter that is universally supported (to the extent that is
supported by the underlying \s-1JSON\s0 modules) is \f(CW\*(C`utf8\*(C'\fR. When this parameter is
enabled all resulting \s-1JSON\s0 will be marked as unicode, and all unicode strings
in the input data structure will be preserved as such.
.Sp
The actual output will vary, for example \s-1JSON\s0 will encode and decode unicode
chars (the resulting \s-1JSON\s0 is not unicode) wheras \s-1JSON::XS\s0 will emit unicode
\&\s-1JSON\s0.
.ie n .IP """handlerType""" 4
.el .IP "\f(CWhandlerType\fR" 4
.IX Item "handlerType"
Takes no arguments, returns a string indicating which \s-1JSON\s0 Module is in use.
.ie n .IP """handler""" 4
.el .IP "\f(CWhandler\fR" 4
.IX Item "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.
.ie n .IP """objToJson""" 4
.el .IP "\f(CWobjToJson\fR" 4
.IX Item "objToJson"
Takes a single argument, a hashref to be converted into \s-1JSON\s0.
It returns the \s-1JSON\s0 text in a scalar.
.ie n .IP """to_json""" 4
.el .IP "\f(CWto_json\fR" 4
.IX Item "to_json"
.PD 0
.ie n .IP """Dump""" 4
.el .IP "\f(CWDump\fR" 4
.IX Item "Dump"
.ie n .IP """encode""" 4
.el .IP "\f(CWencode\fR" 4
.IX Item "encode"
.PD
Aliases for objToJson, can be used interchangeably, regardless of the 
underlying \s-1JSON\s0 module.
.ie n .IP """jsonToObj""" 4
.el .IP "\f(CWjsonToObj\fR" 4
.IX Item "jsonToObj"
Takes a single argument, a string of \s-1JSON\s0 text to be converted
back into a hashref.
.ie n .IP """from_json""" 4
.el .IP "\f(CWfrom_json\fR" 4
.IX Item "from_json"
.PD 0
.ie n .IP """Load""" 4
.el .IP "\f(CWLoad\fR" 4
.IX Item "Load"
.ie n .IP """decode""" 4
.el .IP "\f(CWdecode\fR" 4
.IX Item "decode"
.PD
Aliases for jsonToObj, can be used interchangeably, regardless of the 
underlying \s-1JSON\s0 module.

.SH "ACKNOWLEDGEMENTS"
.IX Header "ACKNOWLEDGEMENTS"
This module came about after discussions on irc.perl.org about the fact 
that there were now six separate \s-1JSON\s0 perl modules with different interfaces.
.PP
In the spirit of Class::Any, JSON::Any was created with the considerable 
help of Matt 'mst' Trout.
