NAME

JSON::RPC::Common::Procedure::Return - JSON-RPC procedure return class

SYNOPSIS

         use JSON::RPC::Common::Procedure::Return;
 
         # create a return from a call, retaining the ID
         my $return = $call->return_result("foo");
 
         # inflate gets a version specific class
         my $return = JSON::RPC::Common::Procedure::Return->inflate(
                 version => "2.0",
                 result  => "foo",
                 id      => $id,
         );
 
         # you can specify a return with an error, it's just an attribute
         my $return = JSON::RPC::Common::Procedure::Return->new(
                 error => ...,
         );
 
 

DESCRIPTION

This class abstracts JSON-RPC procedure returns (results).

Version specific implementation are provided as well.

ATTRIBUTES

id
The ID of the call this is a result for.

Results with no ID are typically error results for parse fails, when the call ID could never be determined.

result
The JSON data that is the result of the call, if any.
error
The error, if any. This is a JSON::RPC::Common::Procedure::Return::Error object (or a version specific subclass).
error_class
The error class to use when instantiating errors.

METHODS

inflate
deflate
Go to and from JSON data.
inflate_error
deflate_error
Helpers for managing the error sub object.
set_error
Calls "create_error" with it's arguments and sets the error to that.

E.g.

         $res->set_error("foo");
         $res->error->message; # "foo"
 
 
create_error
Instantiate a new error of class error_class using ``new_dwim'' in JSON::RPC::Common::Procedure::Return::Error.
