NAME

       Lire::DlfConverterProcess - Object that controls the DLF conversion process

SYNOPSIS

	 use Lire::ImportJob;
	 use Lire::DlfStore;
	 use Lire::DlfConverterProcess;

	 my $src = new Lire::ImportJob( "file", 'pattern' => "/var/log/messages" );
	 my $store = Lire::DlfStore->open( "store" );

	 my $process = new Lire::DlfConverterProcess( $src, $store );

	 $process->run_import_job();

	 print "Log lines read: ",	$process->line_count(), "
";
	 print "DLF records created: ", $process->dlf_count,	"
";
	 print "Errors encountered: ",	$process->errors_count, "
";
	 print "Ignored records: ",	$process->ignored_count,"
";

DESCRIPTION

       This object encapsulates the Lire DLF conversion process. It takes as parameter a Lire::ImportJob and a Lire::DlfStore. It will setup the
       converter and will converter the content of Lire::ImportJob to DLF which will be saved in the Lire::DlfStore.

       The object provides the API to the converter. Methods are also available to query information on the conversion process.

new( $job, $store );
       Create a Lire::DlfConverterProcess that will be used to import the log specified in Lire::ImportJob into DLF records which will be stored
       into Lire::DlfStore.

   run_import_job( [$time] )
       Import the log data from ImportJob as DLF. This method will throw an exception if it is called more than once. The $time parameter will be
       used to determine the time window covered by period. It defaults to the current time.

   job_id()
       Returns the job identifier associated to this process.

   dlf_store()
       Returns the Lire::DlfStore in which this conversion process is storing the DLF records.

   import_job()
       Returns the Lire::ImportJob upon which this conversion process is operating.

   line_count()
       Returns the number of lines processed. This will 0 in case the DLF converter process file and not log lines. During a processing, this is
       always equals to the line that is currently being converted.

   dlf_count()
       Returns the number of DLF records created.

   error_count()
       Returns the number of errors encountered in the conversion process.

   ignored_count()
       Returns the number of records which were ignored in the conversion process.

   saved_count()
       Returns the number of lines which were saved for later processing.

API FOR THE DLF CONVERTERS

       This is the object that encapsulates the Dlf implementation and hides the complexitity of the storage framework from the DLF converter. It
       offers the following methods to the DLf converter.

   write_dlf( $schema, $dlf )
       This writes the $dlf DLF record conforming the $schema's schema in the Lire::DlfStore. The schema is the schema's name (e.g. 'www'). $dlf
       is an hash reference. Keys are the schema's field name. Undefined value means that this field isn't available in that record.

   save_log_line( $line )
       Method that should be used to save $line for a future processing run of the converter on the same Lire::ImportJob.

   ignored_log_line( $line, [ $reason ] )
       Method that can be used by the Lire::DlfConverter to report that the '$line' log line was ignored during that processing. The reason why
       the line was ignored can be given in $reason. For example, syslog-based converter should use that method to report lines that are for
       another 'service' than theirs.

   error( $error_msg, [ $line ] );
       Method that should be used by the Lire::DlfConveter to report that an error was encountered when processing the Lire::ImportJob. $error_msg
       should be used to report the nature of the error. The $line parameter should be used by converter operating on lines to associate the error
       message to a particular line.
