6 Archive::Zip::MemberRead - A wrapper that lets you read Zip archive
7 members as if they were files.
8
10 use Archive::Zip;
11 use Archive::Zip::MemberRead;
12 $zip = Archive::Zip->new("file.zip");
13 $fh = Archive::Zip::MemberRead->new($zip, "subdir/abc.txt");
14 while (defined($line = $fh->getline()))
15 {
16 print $fh->input_line_number . "#: $line\n";
17 }
18
19 $read = $fh->read($buffer, 32*1024);
20 print "Read $read bytes as :$buffer:\n";
21
23 The Archive::Zip::MemberRead module lets you read Zip archive member
24 data just like you read data from files.
25
27 Archive::Zip::Member::readFileHandle()
28 You can get a "Archive::Zip::MemberRead" from an archive member by
29 calling readFileHandle():
30
31 my $member = $zip->memberNamed('abc/def.c');
32 my $fh = $member->readFileHandle();
33 while (defined($line = $fh->getline()))
34 {
35 # ...
36 }
37 $fh->close();
38
39 Archive::Zip::MemberRead->new($zip, $fileName)
40 Archive::Zip::MemberRead->new($zip, $member)
41 Archive::Zip::MemberRead->new($member)
42 Construct a new Archive::Zip::MemberRead on the specified member.
43
44 my $fh = Archive::Zip::MemberRead->new($zip, 'fred.c')
45
46 setLineEnd(expr)
47 Set the line end character to use. This is set to \n by default
48 except on Windows systems where it is set to \r\n. You will only
49 need to set this on systems which are not Windows or Unix based and
50 require a line end different from \n. This is a class method so
51 call as "Archive::Zip::MemberRead"->setLineEnd($nl)
52
53 rewind()
54 Rewinds an "Archive::Zip::MemberRead" so that you can read from it
55 again starting at the beginning.
56
57 input_record_separator(expr)
58 If the argument is given, input_record_separator for this instance
59 is set to it. The current setting (which may be the global $/) is
60 always returned.
61
62 input_line_number()
63 Returns the current line number, but only if you're using
64 getline(). Using read() will not update the line number.
65
66 close()
67 Closes the given file handle.
68
69 buffer_size([ $size ])
70 Gets or sets the buffer size used for reads. Default is the chunk
71 size used by Archive::Zip.
72
73 getline()
74 Returns the next line from the currently open member. Makes sense
75 only for text files. A read error is considered fatal enough to
76 die. Returns undef on eof. All subsequent calls would return
77 undef, unless a rewind() is called. Note: The line returned has
78 the input_record_separator (default: newline) removed.
79
80 getline( { preserve_line_ending => 1 } )
81 Returns the next line including the line ending.
82
83 read($buffer, $num_bytes_to_read)
84 Simulates a normal read() system call. Returns the no. of bytes
85 read. "undef" on error, 0 on eof, e.g.:
86
87 $fh = Archive::Zip::MemberRead->new($zip, "sreeji/secrets.bin");
88 while (1)
89 {
90 $read = $fh->read($buffer, 1024);
91 die "FATAL ERROR reading my secrets !\n" if (!defined($read));
92 last if (!$read);
93 # Do processing.
94 ....
95 }
