Archive::Zip::MemberRead(3)

NAME
Archive::Zip::MemberRead - A wrapper that lets you read Zip archive members as if they were files.

SYNOPSIS
  use Archive::Zip;
  use Archive::Zip::MemberRead;
  $zip = new Archive::Zip("file.zip");
  $fh  = new Archive::Zip::MemberRead($zip, "subdir/abc.txt");
  while (defined($line = $fh->getline()))
  {
      print $fh->input_line_number . "#: $line\n";
  }

  $read = $fh->read($buffer, 32*1024);
  print "Read $read bytes as :$buffer:\n";

DESCRIPTION
The Archive::Zip::MemberRead module lets you read Zip archive member data just like you read data from files.

METHODS

Archive::Zip::Member::readFileHandle()
    You can get a "Archive::Zip::MemberRead" from an archive member by calling "readFileHandle()":

      my $member = $zip->memberNamed('abc/def.c');
      my $fh = $member->readFileHandle();
      while (defined($line = $fh->getline()))
      {
              # ...
      }
      $fh->close();

Archive::Zip::MemberRead->new($zip, $fileName)
Archive::Zip::MemberRead->new($zip, $member)
Archive::Zip::MemberRead->new($member)
    Construct a new Archive::Zip::MemberRead on the specified member.

      my $fh = Archive::Zip::MemberRead->new($zip, 'fred.c')

rewind()
    Rewinds an "Archive::Zip::MemberRead" so that you can read from it again starting at the beginning.

input_line_number()
    Returns the current line number, but only if you're using "getline()". Using "read()" will not update the line number.

close()
    Closes the given file handle.

buffer_size([ $size ])
    Gets or sets the buffer size used for reads. Default is the chunk size used by Archive::Zip.

getline()
    Returns the next line from the currently open member. Makes sense only for text files. A read error is considered fatal enough to die. Returns undef on eof. All subsequent calls would return undef, unless a rewind() is called. Note: The line returned has the newline removed.

read($buffer, $num_bytes_to_read)
    Simulates a normal "read()" system call. Returns the no. of bytes read. "undef" on error, 0 on eof, e.g.:

      $fh = new Archive::Zip::MemberRead($zip, "sreeji/secrets.bin");
      while (1)
      {
        $read = $fh->read($buffer, 1024);
        die "FATAL ERROR reading my secrets !\n" if (!defined($read));
        last if (!$read);
        # Do processing.
        ....
       }
