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 = 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";
The Archive::Zip::MemberRead module lets you read Zip archive
member data just like you read data from files.
- 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.
....
}
