NAME

6       Test::Valgrind::Tool - Base class for Test::Valgrind tools.
7

VERSION

9       Version 1.19
10

DESCRIPTION

12       This class is the base for Test::Valgrind tools.
13
14       They wrap around "valgrind" tools by parsing its output and sending
15       reports to the parent session whenever an error occurs.  They are
16       expected to function both in suppressions generation and in analysis
17       mode.

METHODS

20   "requires_version"
21           my $required_version = $tvt->requires_version;
22
23       The minimum "valgrind" version needed to run this tool.  Defaults to
24       3.1.0.
25
26   "new"
27           my $tvt = Test::Valgrind::Tool->new(tool => $tool);
28
29       Creates a new tool object of type $tool by requiring and redispatching
30       the method call to the module named $tool if it contains '::' or to
31       "Test::Valgrind::Tool::$tool" otherwise.  The class represented by
32       $tool must inherit this class.
33
34   "new_trainer"
35           my $tvt_train = Test::Valgrind::Tool->new_trainer;
36
37       Creates a new tool object suitable for generating suppressions.
38
39       Defaults to return "undef", which skips suppression generation.
40
41   "parser_class"
42           my $parser_class = $tvt->parser_class($session);
43
44       Returns the class from which the parser for this tool output will be
45       instanciated.
46
47       This method must be implemented when subclassing.
48
49   "report_class"
50           my $report_class = $tvt->report_class($session);
51
52       Returns the class in which suppression reports generated by this tool
53       will be blessed.
54
55       This method must be implemented when subclassing.
56
57   "args"
58           my @args = $tvt->args($session);
59
60       Returns the list of tool-specific arguments that are to be passed to
61       "valgrind".  All the suppression arguments are already handled by the
62       session.
63
64       Defaults to the empty list.
65
66   "suppressions_tag"
67           my $tag = $tvt->suppressions_tag($session);
68
69       Returns a identifier that will be used to pick up the right
70       suppressions for running the tool, or "undef" to indicate that no
71       special suppressions are needed.
72
73       This method must be implemented when subclassing.
74
75   "start"
76           $tvt->start($session);
77
78       Called when the $session starts.
79
80       Defaults to set "started" in Test::Valgrind::Component.
81
82   "filter"
83           my $filtered_report = $tvt->filter($session, $report);
84
85       The $session calls this method after receiving a report from the parser
86       and before letting the command filter it.  You can either return a
87       mangled $report (which does not need to be a clone of the original) or
88       "undef" if you want the action to ignore it completely.
89
90       Defaults to the identity function.
91
92   "finish"
93           $tvt->finish($session);
94
95       Called when the $session finishes.
96
97       Defaults to clear "started" in Test::Valgrind::Component.
