1 package Test::Valgrind::Tool::SuppressionsParser;
8 Test::Valgrind::Tool::SuppressionsParser - Mock Test::Valgrind::Tool for parsing valgrind suppressions.
16 our $VERSION = '1.01';
20 This class provides a default C<parse_suppressions> method, so that real tools for which suppressions are meaningful can exploit it by inheriting.
22 It's not meant to be used directly as a tool.
26 use base qw/Test::Valgrind::Carp/;
32 Just a croaking stub to remind you not to use this class as a real tool.
34 If your tool both inherit from this class and from C<Test::Valgrind::Tool>, and that you want to dispatch the call to your C<new> to its ancestors', be careful with C<SUPER> which may end up calling this dieing version of C<new>.
35 The solution is to either put C<Test::Valgrind::Tool> first in the C<@ISA> list or to explicitely call C<Test::Valgrind::Tool::new> instead of C<SUPER::new>.
39 sub new { shift->_croak('This mock tool isn\'t meant to be used directly') }
41 =head2 C<report_class_suppressions $session>
43 Generated reports are L<Test::Valgrind::Report::Suppressions> objects.
44 Their C<data> member contains the raw text of the suppression.
48 sub report_class_suppressions { 'Test::Valgrind::Report::Suppressions' }
50 =head2 C<parse_suppressions $session, $fh>
52 Parses the filehandle C<$fh> fed with the output of F<valgrind --gen-suppressions=all> and sends a report to the session C<$session> for each suppression.
