NAME

Data::MessagePack::Unpacker - messagepack streaming deserializer

SYNOPSIS

use Data::Dumper;
my $up = Data::MessagePack::Unpacker->new;

open my $fh, $data or die $!;

my $offset = 0;
while( read($fh, my $buf, 1024) ) {
    $offset = $up->execute($buf, $offset);
    if($up->is_finished) {
        print Dumper($up->data);
    }
}

DESCRIPTION

This is a streaming deserializer for messagepack.

METHODS

my $up = Data::MessagePack::Unpacker->new()

creates a new instance of the stream deserializer.

$up->utf8([$bool])

sets utf8 mode. true if $bool is omitted. returns $up itself.

If utf8 mode is enabled, strings will be decoded as UTF-8.

The utf8 mode is disabled by default.

my $ret = $up->get_utf8()

returns the utf8 mode flag of $up.

$offset = $up->execute($data, $offset);

$offset = $up->execute_limit($data, $offset, $limit)

parses unpacked $data from $offset to $limit. returns a new offset of $data, which is for the next <execute()>.

If $data is insufficient, $offset does not change, saving $data in internal buffers.

my $bool = $up->is_finished();

is this deserializer finished?

my $data = $up->data();

returns the deserialized object.

$up->reset();

resets the stream deserializer, without memory zone.
