21 | =head1 NAME | |
22 | ||
23 | IO::Uncompress::Brotli - Read Brotli buffers/streams | |
24 | ||
25 | =head1 SYNOPSIS | |
26 | ||
27 | use IO::Uncompress::Brotli; | |
28 | ||
29 | # uncompress a buffer | |
30 | my $decoded = unbro $encoded; | |
31 | ||
32 | # uncompress a stream | |
33 | my $bro = IO::Uncompress::Brotli->create; | |
34 | while(have_input()) { | |
35 | my $block = get_input_block(); | |
36 | my $decoded_block = $bro->decompress($block); | |
37 | handle_output_block($decoded_block); | |
38 | } | |
39 | ||
40 | =head1 DESCRIPTION | |
41 | ||
42 | IO::Uncompress::Brotli is a module that decompresses Brotli buffers | |
43 | and streams. Despite its name, it is not a subclass of | |
44 | L<IO::Uncompress::Base> and does not implement its interface. This | |
45 | will be rectified in a future release. | |
46 | ||
47 | =head2 One-shot interface | |
48 | ||
49 | If you have the whole buffer in a Perl scalar use the B<unbro> | |
50 | function. | |
51 | ||
52 | =over | |
53 | ||
54 | =item B<unbro>(I<$input>) | |
55 | ||
56 | Takes a whole compressed buffer as input and returns the decompressed | |
57 | data. This function relies on the BrotliDecompressedSize function. In | |
58 | other words, it only works if the buffer has a single meta block or | |
59 | two meta-blocks where the first is uncompressed and the second is | |
60 | empty. | |
61 | ||
62 | Exported by default. | |
63 | ||
64 | =back | |
65 | ||
66 | =head2 Streaming interface | |
67 | ||
68 | If you want to process the data in blocks use the object oriented | |
69 | interface. The available methods are: | |
70 | ||
71 | =over | |
72 | ||
73 | =item IO::Uncompress::Brotli->B<create> | |
74 | ||
75 | Returns a IO::Uncompress::Brotli instance. Please note that a single | |
76 | instance cannot be used to decompress multiple streams. | |
77 | ||
78 | =item $bro->B<decompress>(I<$block>) | |
79 | ||
80 | Takes the a block of compressed data and returns a block of | |
81 | uncompressed data. Dies on error. | |
