SYNOPSIS

  use Archive::Zip;
  use Archive::Zip::MemberRead;
  $zip = Archive::Zip->new("file.zip");
  $fh  = Archive::Zip::MemberRead->new($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

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')
    

setLineEnd(expr)

Set the line end character to use. This is set to \n by default except on Windows systems where it is set to \r\n. You will only need to set this on systems which are not Windows or Unix based and require a line end different from \n. This is a class method so call as "Archive::Zip::MemberRead"->"setLineEnd($nl)"

rewind()

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

input_record_separator(expr)

If the argument is given, input_record_separator for this instance is set to it. The current setting (which may be the global $/) is always returned.

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 input_record_separator (default: newline) removed.

getline( { preserve_line_ending => 1 } )

Returns the next line including the line ending.

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.:

  $fh = Archive::Zip::MemberRead->new($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.
    ....
   }
