Archive::Zip::MemberRead - A wrapper that lets you read Zip archive members as if they were files.
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";
The Archive::Zip::MemberRead module lets you read Zip archive member data just like you read data from files.
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())) { # ... } $fh->close();
new($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.
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.
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. .... }
