VERSION

version 0.03

SYNOPSIS

my $pool = Protobuf::DescriptorPool->generated_pool;
my $file_def = $pool->find_file_by_name('my/app/stuff.proto');

if ($file_def) {
    print "File Name: ", $file_def->name, "
";
    print "Package: ", $file_def->get_package, "
";
    for my $i (0 .. $file_def->top_level_message_count - 1) {
        my $msg = $file_def->get_top_level_message($i);
        print "  Message: ", $msg->full_name, "

DESCRIPTION

This class represents the descriptor for a single .proto file. It contains information about the file's name, package, and the top-level messages, enums, and extensions defined within it.

Instances of this class are usually obtained from a Protobuf::DescriptorPool when a file is loaded, for example, via $pool->add_serialized_file().

METHODS

name()

Returns the path/name of the .proto file.

get_package()

Returns the package name declared in the .proto file.

top_level_message_count()

Returns the number of top-level message types defined in this file.

get_top_level_message($index)

Returns the Protobuf::Descriptor::MessageDef for the top-level message at the given $index (0-based).
