NAME

JSON::RPC::Common::Procedure::Call - JSON RPC Procedure Call base class.

VERSION

version 0.11

SYNOPSIS

use JSON::RPC::Common::Procedure::Call;

my $req = JSON::RPC::Common::Procedure::Call->inflate({ ... });

warn "HALLO JSONRPC VERSION " . $req->version;

DESCRIPTION

A JSON-RPC Procedure Call (ed: *rolls eys*, what was wrong with "request"?) is either a notification or a method invocation in JSON-PRC.

See http://json-rpc.org/wiki/specification for more details.

ATTRIBUTES

All attributes are read only unless otherwise specified.

version

id

The request ID.

Used to correlate a request to a response.

method

The name of the method to invoke.

params

Returns a reference to the parameters hash or array.

return_class

error_class

The classes to instantiate the response objects.

These vary per subclass.

METHODS

inflate

A factory constructor. Delegates to new on a subclass based on the protocol version.

This is the recommended constructor.

deflate

Flatten to JSON data

new

The actual constructor.

Not intended for normal use on this class, you should use a subclass most of the time.

Calling JSON::RPC::Common::Procedure::Call->new will construct a call with an undefined version, which cannot be deflated (and thus sent over the wire). This is still useful for testing your own code's RPC hanlding, so this is not allowed.

params_list

Dereferences params regardless of representation.

Returns a list of positionals or a key/value list.

return_result $result

return_error %error_params

Create a new JSON::RPC::Common::Procedure::Return with or without an error.

is_notification

Whether this request is a notification (a method that does not need a response).

is_service

Whether this request is a JSON-RPC 1.1 service method (e.g. system.describe).

This method is always false for 1.0 and 2.0.

call $obj

A convenience method to invoke the call on $obj and create a new return with the return value.
