8 Test::Valgrind::Tool::memcheck - Run an analysis through the memcheck tool.
16 our $VERSION = '1.10';
20 This tool parses the XML output of a C<memcheck> run with L<XML::Twig>.
24 use base qw/Test::Valgrind::Tool/;
28 This class inherits L<Test::Valgrind::Tool>.
30 =head2 C<requires_version>
32 This tool requires C<valgrind> C<3.1.0>.
36 sub requires_version { '3.1.0' }
38 =head2 C<< new callers => $callers, ... >>
40 Your usual constructor.
42 C<$callers> specifies the number of stack frames to inspect for errors : the bigger you set it, the more granular the analysis is.
44 Other arguments are passed straight to C<< Test::Valgrind::Tool->new >>.

64 sub new_trainer { shift->new(callers => 50) }
68 Read-only accessor for the C<callers> option.
72 sub callers { $_[0]->{callers} }
74 sub suppressions_tag { 'memcheck-' . $_[1]->version }
76 =head2 C<parser_class $session>
78 This tool uses a C<Test::Valgrind::Parser::XML::Twig> parser in analysis mode, and a C<Test::Valgrind::Parser::Suppressions::Text> parser in suppressions mode.

97 This tool emits C<Test::Valgrind::Tool::memcheck::Report> object reports in analysis mode.
102 my ($self, $session) = @_;
