Archive::Zip::MemberReUser)Contributed Perl DocumenArchive::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 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.
....
}
