=head1 DESCRIPTION
This class extends L<Siebel::Srvrmgr::ListParser::Output::Tabular> base class adding support for parsing C<list comp> commands.
The module is capable of identifying output of several servers configured in the enterprise and organizes the components
found for each server.
It is expected that the C<srvrmgr> program has a proper configuration for the C<list comp> command. The configuration
can see below:
srvrmgr> configure list comp
SV_NAME (31): Server name
CC_ALIAS (31): Component alias
CC_NAME (76): Component name
CT_ALIAS (31): Component type alias
CG_ALIAS (31): Component Group Alias
CC_RUNMODE (31): Component run mode (enum)
CP_DISP_RUN_STATE (61): Component display run state
CP_NUM_RUN_TASKS (11): Current number of running tasks
CP_MAX_TASKS (11): Maximum tasks configured
CP_ACTV_MTS_PROCS (11): Active MTS control processes
CP_MAX_MTS_PROCS (11): Maximum MTS control processes
CP_START_TIME (21): Component start time
CP_END_TIME (21): Component end time
CP_STATUS (251): Component-reported status
CC_INCARN_NO (23): Incarnation Number
CC_DESC_TEXT (251): Component description
This output above should be the default but it will be necessary to have the configuration below
(check the difference of size for each column):
srvrmgr> configure list comp
SV_NAME (31): Server name
CC_ALIAS (31): Component alias
CC_NAME (76): Component name
CT_ALIAS (31): Component type alias
CG_ALIAS (31): Component GRoup Alias
CC_RUNMODE (31): Component run mode (enum)
CP_DISP_RUN_STATE (61): Component display run state
CP_NUM_RUN_TASKS (16): Current number of running tasks
CP_MAX_TASKS (12): Maximum tasks configured
CP_ACTV_MTS_PROCS (17): Active MTS control processes
CP_MAX_MTS_PROCS (16): Maximum MTS control processes
CP_START_TIME (21): Component start time
CP_END_TIME (21): Component end time
CP_STATUS (251): Component-reported status
CC_INCARN_NO (23): Incarnation Number
CC_DESC_TEXT (251): Component description
because L<Siebel::Srvrmgr::ListParser::Output::Tabular::ListComp::Comp> will expect to have all columns names without being
truncated. This class will check those columns names and order and it will raise an exception if it found something different
from the expected.
To enable that, execute the following commands in the C<srvrmgr> program:
set ColumnWidth true
configure list components show SV_NAME(31), CC_ALIAS(31), CC_NAME(76), CT_ALIAS(31), CG_ALIAS(31), CC_RUNMODE(31), CP_DISP_RUN_STATE(61),\
CP_NUM_RUN_TASKS(16), CP_MAX_TASKS(12), CP_ACTV_MTS_PROCS(17), CP_MAX_MTS_PROCS(16), CP_START_TIME(21), CP_END_TIME(21),\
CP_STATUS(251), CC_INCARN_NO(23), CC_DESC_TEXT(251)
Saving this configuration as a preference and loading it everytime is a good idea too.
=head1 ATTRIBUTES
=head2 last_server
A string that represents the last associated server from the list of components read from output.
By default, the value of it is an empty string.
This attribute is used during parsing of C<list comp> command and is a read-only attribute.
=cut
has 'last_server' => (
is => 'ro',
isa => 'Str',
reader => 'get_last_server',
writer => '__set_last_server',
default => '',
init_arg => undef
);
=pod
=head2 comp_attribs
An array reference with the components attributes. This is a read-only attribute.
=cut
has 'comp_attribs' => (
is => 'ro',
isa => 'ArrayRef',
reader => 'get_comp_attribs',
builder => '_build_comp_attribs',
writer => '_set_comp_attribs',
);
=pod
=head2 servers
This is an array reference with the servers found during processing of the C<list components> output.
=cut
has 'servers' => (
is => 'rw',
isa => 'ArrayRef',
reader => 'get_servers',
default => sub { return [] }
);

=head2 get_comp_attribs
Returns the value of C<comp_attribs> attribute.
=head2 get_last_server
Returns the C<last_server> attribute.
=head2 get_servers
Returns the value of C<servers> attribute.
=head2 get_server
Expects as parameter the name of a server which output was parsed.
If the server exists in the C<servers> attribute, it returns a L<Siebel::Srvrmgr::ListParser::Output::Tabular::ListComp::Server>
object. Otherwise it will return C<undef>.
