Archive::Zip::MemberRead(3)          User Contributed Perl Documentation         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 = 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
       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')

       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 diffrent 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 argumnet 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.

       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.
               ....
              }
