=head1 NAME

Path::Class::URI - Serializes and deserializes Path::Class objects as file:// URI

=head1 SYNOPSIS

  use Path::Class;
  use Path::Class::URI;

  my $file = file('bob', 'john.txt');
  my $uri  = $file->uri; # file:bob/john.txt

  file('', 'tmp', 'bar.txt')->uri; # file:///tmp/bar.txt

  my $file = file_from_uri("file:///tmp/bar.txt"); # or URI::file object
  $fh = $file->open;

=head1 DESCRIPTION

Path::Class::URI is an extension to Path::Class to serialize file path
from and to I<file://> form URI objects.

This module encodes and decodes non URI-safe characters using its
literal byte encodings. If you call I<uri> methods on Win32 Path::File
objects, you'll get local filename encodings.

If you want to avoid that and always use UTF-8 filename encodings in
URI, see L<Path::Class::Unicode> bundled in this distribution.

=head1 METHODS

=over 4

=item uri (Path::Class::Entity)

  $uri = $file->uri;
  $uri = $dir->uri;

returns URI object representing Path::Class file and directory.

=item from_uri (Path::Class::Entity)

  $file = Path::Class::File->from_uri($uri);
  $dir  = Path::Class::Dir->from_uri($uri);

Deserializes URI object (or string) into Path::Class objects.

=item file_from_uri, dir_from_uri

Shortcuts for those I<from_uri> methods. Exported by default.
