archive::zip::memberread5.18
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
";
}
$read = $fh->read($buffer, 32*1024);
print "Read $read bytes as :$buffer:
";
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
by default except on Windows systems where it is set to
. You will only need
to set this on systems which are not Windows or Unix based and require a line end different from
. 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 !
" if (!defined($read));
last if (!$read);
# Do processing.
....
}
