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.
....
}
