NAME

6       Convert::Binary::C::Cached - Caching for Convert::Binary::C

SYNOPSIS

9         use Convert::Binary::C::Cached;
10         use Data::Dumper;
11
12         #------------------------
13         # Create a cached object
14         #------------------------
15         $c = Convert::Binary::C::Cached->new(
16                Cache   => '/tmp/cache.c',
17                Include => [
18                  '/usr/lib/gcc/i686-pc-linux-gnu/4.1.2/include',
19                  '/usr/include',
20                ],
21              );
22
23         #----------------------------------------------------
24         # Parse 'time.h' and dump the definition of timespec
25         #----------------------------------------------------
26         $c->parse_file('time.h');

DESCRIPTION

31       Convert::Binary::C::Cached simply adds caching capability to Con‐
32       vert::Binary::C. You can use it in just the same way that you would use
33       Convert::Binary::C. The interface is exactly the same.
34
35       To use the caching capability, you must pass the "Cache" option to the
36       constructor. If you don't pass it, you will receive an ordinary Con‐
37       vert::Binary::C object. The argument to the "Cache" option is the file
38       that is used for caching this object.
39
40       The caching algorithm automatically detects when the cache file cannot
41       be used and the original code has to be parsed.  In that case, the
42       cache file is updated. An update of the cache file can be triggered by
43       one or more of the following factors:
44
45       · The cache file doesn't exist, which is obvious.
46
47       · The cache file is corrupt, i.e. cannot be parsed.
48
49       · The object's configuration has changed.
50
51       · The embedded code for a "parse" method call has changed.
52
53       · At least one of the files that the object depends on does not exist
54         or has a different size or a different modification or change time‐
55         stamp.
56

LIMITATIONS

58       You cannot call "parse" or "parse_file" more that once when using a
59       Convert::Binary::C::Cached object. This isn't a big problem, as you
60       usually don't call them multiple times.
61
62       If a dependency file changes, but the change affects neither the size
63       nor the timestamps of that file, the caching algorithm cannot detect
64       that an update is required.
