NAME

6       Test::Valgrind::Command - Base class for Test::Valgrind commands.
7

VERSION

9       Version 1.19

DESCRIPTION

12       This class is the base for Test::Valgrind commands.
13
14       Commands gather information about the target of the analysis.  They
15       should also provide a default setup for generating suppressions.
16

METHODS

18   "new"
19           my $tvc = Test::Valgrind::Command->new(
20            command => $command,
21            args    => \@args,
22           );
23
24       Creates a new command object of type $command by requiring and
25       redispatching the method call to the module named $command if it
26       contains '::' or to "Test::Valgrind::Command::$command" otherwise.  The
27       class represented by $command must inherit this class.
28
29       The "args" key is used to initialize the "args" accessor.
30
31   "new_trainer"
32       Creates a new command object suitable for generating suppressions.
33
34       Defaults to return "undef", which skips suppression generation.
35
36   "args"
37           my @args = $tvc->args($session);
38
39       Returns the list of command-specific arguments that are to be passed to
40       "valgrind".
41
42       Defaults to return the contents of the "args" option.
43
44   "env"
45           my $env = $tvc->env($session);
46
47       This event is called in scalar context before the command is ran, and
48       the returned value goes out of scope when the analysis ends.  It's
49       useful for e.g. setting up %ENV for the child process by returning an
50       Env::Sanctify object, hence the name.
51
52       Defaults to void.
53
54   "suppressions_tag"
55           my $tag = $tvc->suppressions_tag($session);
56
57       Returns a identifier that will be used to pick up the right
58       suppressions for running the command, or "undef" to indicate that no
59       special suppressions are needed.
60
61       This method must be implemented when subclassing.
62
63   "check_suppressions_file"
64           my $supp_ok = $tvc->check_suppressions_file($file);
65
66       Returns a boolean indicating whether the suppressions contained in
67       $file are compatible with the command.
68
69       Defaults to true.
70
71   "filter"
72           my $filtered_report = $tvc->filter($session, $report);
73
74       The $session calls this method after receiving a report from the tool
75       and before forwarding it to the action.  You can either return a
76       mangled $report (which does not need to be a clone of the original) or
77       "undef" if you want the action to ignore it completely.
78
79       Defaults to the identity function.
