=head1 NAME
Siebel::Srvrmgr::ListParser::Output::Tabular::ListTasks - subclass to parse list tasks command

=head1 SYNOPSIS
See L<Siebel::Srvrmgr::ListParser::Output::Tabular> for examples.
=head1 DESCRIPTION
This subclass of L<Siebel::Srvrmgr::ListParser::Output::Tabular> parses the output of the command C<list tasks>.
It is expected that the C<srvrmgr> program has a proper configuration for the C<list tasks> command. The default configuration
can be seen below:
srvrmgr> configure list tasks
SV_NAME (31): Server name
CC_ALIAS (31): Component alias
TK_TASKID (11): Internal task id
TK_PID (11): Task process id
TK_DISP_RUNSTATE (61): Task run state
CC_RUNMODE (31): Task run mode
TK_START_TIME (21): Task start time
TK_END_TIME (21): Task end time
TK_STATUS (251): Task-reported status
CG_ALIAS (31): Component group alias
TK_PARENT_TASKNUM (11): Parent task id
CC_INCARN_NO (23): Incarnation Number
TK_LABEL (76): Task Label
TK_TASKTYPE (31): Task Type
TK_PING_TIME (11): Last ping time for task
If you want to use fixed width configuration from C<srvrmgr> this will be the expected configuration:
srvrmgr> configure list tasks
SV_NAME (31): Server name
CC_ALIAS (31): Component alias
TK_TASKID (11): Internal task id
TK_PID (11): Task process id
TK_DISP_RUNSTATE (61): Task run state
If you want to use the field delimited output from C<srvrmgr> then this the expected configuration:
srvrmgr> configure list tasks
SV_NAME (31): Server name
CC_ALIAS (31): Component alias
TK_TASKID (11): Internal task id
TK_PID (11): Task process id
TK_DISP_RUNSTATE (61): Task run state
CC_RUNMODE (31): Task run mode
TK_START_TIME (21): Task start time
TK_END_TIME (21): Task end time
TK_STATUS (251): Task-reported status
CG_ALIAS (31): Component group alias
TK_PARENT_TASKNUM (18): Parent task id
CC_INCARN_NO (23): Incarnation Number
TK_LABEL (76): Task Label
TK_TASKTYPE (31): Task Type
TK_PING_TIME (12): Last ping time for task
The order of the fields is important too: everytime those fields are parsed, if they do not follow the order above an exception
will be raised.

=head1 METHODS
Some methods from the parent classes are overrided.
=head2 count_tasks
Returns an integer representing the number of tasks recovered from the parsed output.
Expects a string as parameter being the Siebel Server name, so the number of tasks are those related to the
server passed as argument.
=cut
sub count_tasks {
my $self = shift;
my $server = shift;
my $server_ref = $self->val_items_server($server);
return scalar( @{$server_ref} );
}
=pod
=head2 get_tasks
Returns an iterator to iterate over the list of tasks of a Siebel Server given as argument.
At each invocation of the iterator, a instance of L<Siebel::Srvrmgr::ListParser::Output::ListTasks::Task> is return,
or C<undef> in the case that there are no more tasks to return.
Beware that depending on the type of output parsed, the returned instances will have more or less attributes with
values.
To be compatible with the role L<Siebel::Srvrmgr::ListParser::Output::Duration>, fixed width output data will have a default
value of '2000-00-00 00:00:00' for C<start_datetime> attribute, which is basically useless if you need that of information.
You should use delimited data for that.

=head1 CAVEATS
Unfornately the results of C<list tasks> command does not work as expected if a fixed width output type is selected due a bug with
the C<srvrmgr> itself in recent versions of Siebel (8 and beyond).
Even though a L<Siebel::Srvrmgr::ListParser> instance is capable of identifying a C<list tasks> command output, this class is
not being able to properly parse the output from the command.
The problem is that the output is not following the expected fixed width as setup with the
C<configure list tasks show...> command: with that, the output width is resized depending on the content of each
column and thus impossible to predict how to parse it correctly.
That said, this class will make all the fields available from C<list tasks> B<only> if a field delimited output was
configured within C<srvrmgr>.
