NAME

Siebel::Srvrmgr::ListParser::FSA - the FSA::Rules class specification for Siebel::Srvrmgr::ListParser

SYNOPSIS

        use FSA::Rules;
        my $fsa = Siebel::Srvrmgr::ListParser::FSA->get_fsa();
    # do something with $fsa

    # for getting a diagram exported in your currently directory with a onliner
    perl -MSiebel::Srvrmgr::ListParser::FSA -e "Siebel::Srvrmgr::ListParser::FSA->export_diagram"

DESCRIPTION

Siebel::Srvrmgr::ListParser::FSA subclasses the state machine implemented by Siebel::Srvrmgr::ListParser class.

This class also have a Log::Log4perl instance built in the FSA::Rules instance returned by get_fsa method.

EXPORTS

Nothing.

METHODS

export_diagram

Creates a PNG file with the state machine diagram in the current directory where the method was invoked.

new

Returns the state machine object defined for usage with a Siebel::Srvrmgr::ListParser instance.

free_refs

This methods eliminates all circular references that version 0.31 of FSA::Rules has, which makes it impossible to call the DESTROY before the program termination.

It should be invoked before program termination, possibly also in DESTROY and DEMOLISH methods of objects to give to the Perl interpreter a change to release memory by calling the related DESTROY methods of FSA::Rules and FSA::State instances.

SEE ALSO

• Siebel::Srvrmgr::ListParser

CAVEATS

This class has some problems, most due the API of FSA::Rules: since the state machine is a group of references to subroutines, it holds references to Siebel::Srvrmgr::ListParser, which basically causes circular references between the two classes.

There is some workaround to the caused memory leaks due this configuration, but in future releases FSA::Rules may be replaced to something else.
