NAME

Thrift::Parser - A Thrift message (de)serialization OO representation

SYNOPSIS

use Thrift;
use Thrift::Parser;
use Thrift::IDL;

my $parser = Thrift::Parser->new(
    idl => Thrift::IDL->parse_thrift_file('tutorial.thrift'),
    service => 'Calculator',
);

## Parse a payload

# Obtain a Thrift::Protocol subclass somehow with a loaded buffer
my $buffer   = ...;
my $protocol = Thrift::BinaryProtocol->new($buffer);

my $message = $parser->parse_message($protocol);

print "Received method call " . $message->method->name . "\n";

## Use the auto-generated classes to create request/responses

my $request = tutorial::Calculator::add->compose_message_call(
  num1 => 15,
  num2 => 33,
);

my $response = $request->compose_reply(48);

DESCRIPTION

This module provides strict typing and full object orientation of all the Thrift types. It allows you, with a Thrift::IDL object, to create a parser which can parse any Thrift::Protocol object into a message object, and creates dynamic classes according to the IDL specification, allowing you to create method calls, objects, and responses.

METHODS

new

my $parser = Thrift::Parser->new(
  idl => Thrift::IDL->parse_thrift_file('..'),
  service => 'myServiceName',
)

Creates the Parser object and dynamic classes from the IDL file.

parse_message

my $message = $parser->parse_message($transport);

Given a Thrift::Transport object, the parser will create a Thrift::Parser::Message object.

full_docs_to_dir

$parser->full_docs_to_dir($dir, $format);

Using the dynamically generated classes, this will create 'pod' or 'pm' files in the target directory in the following format:

$dir/tutorial::Calculator::testVars.pod
(or with format 'pm')
$dir/tutorial/Calculator/testVars.pm

The directory will be created if it doesn't exist.

INTERNAL METHODS

parse_structure

my $fieldset = $parser->parse_structure($transport, $thrift_idl_method->arguments);

Returns a Thrift::Parser::FieldSet. Attempts to read a structure off the transport, using an array of Thrift::IDL::Field objects to define the specification of the structure.

parse_type

my $typed_value = $parser->parse_type($transport, { idl => $thrift_idl_type_object || type => 4 });

Reads a single value off the transport and returns it as an object in a Thrift::Parser::Type subclass.

idl_type_class

my $parser_type_class = $parser->idl_type_class($thrift_idl_type_object);

Maps the given Thrift::IDL::Type object to one in my parser namespace. If it's a custom type, it'll map into a dynamic class.

resolve_idl_type

my $thrift_idl_type_object = $parser->resolve_idl_type($thrift_idl_custom_type_object);

Returns the base Thrift::IDL::Type object from the given Thrift::IDL::Type::Custom object
