PARALOOP::PLUGIN::Dummy - Template object
PARALOOP::PLUGIN::BpInput
This plugin reads the next record from the input file, copies this record to the output file, then sleeps a few seconds: this is dummy, but this is just a demo, and a template to help you write your plugins.
PARALOOP_Dummy_sleep_path path to the sleep program (default sleep) PARALOOP_Dummy_sleep_time time to sleep (default 6)
WhatParaloopPlugin my $msg=$obj->WhatParaloopPlugin()
Parameters my $msg=$obj->Parameters()
New my $obj = PARALOOP::Dummy->New(-params => $params, -log => $o_log);
Exec my ($incr_size,$error,$killed) = $obj->Exec();
SetOutputFile $obj->SetOutputFile('filename');
NextRecord my $seq = $obj->NextRecord(); SkipRecords $obj->SkipRecords($n); Tell() my $position = $obj->Tell(); TellLength my $length = $obj->TellLength(); SetOutputFile $obj->SetOutputFile('filename');
Usage: my $msg = PARALOOP::Dummy::WhatParaloopPlugin() or my $msg = $obj->WhatParaloopPlugin() Function: Return some information (2 lines max) on the plugin An object is NOT considered as a plugin if this function is not implemented Arg: none ($self is ignored) Return: A message describing the plugin (1 or 2 lines)
Usage: my $msg = PARALOOP::Dummy::Parameters() or my $msg = $obj->Parameters() Function: Return the list of allowed parameters for this plugin If your plugin defines some parameters, it is good pratice adding this function, to display those parameters when the --parameters switch of paraloop.pl is used. However, this is not mandatory Arg: none ($self is ignored) Return: A message describing the plugin (1 or 2 lines)
Usage: CALLED BY _Initializable::New my obj = PARALOOP::Dummy->New(-params => $params, -log => $o_log); Access: private (use New instead) procedure: Init the object Return: nothing Args: -params = an object of class ParamParser (already initialized) -log = an object of class Log (already initialized) globals: none The plugin is created by paraloop at initialization, BEFORE calling qsub; this lets you the opportunity to check everything carefully, so you can hope not to have any error message when your job will be submitted later If a resource is created (file, temporary directory, etc) it must be deleted in DESTROY
Usage: The destructor of the object undef($obj); Access: public procedure: Destroyes the resources allocated by __Init Return: nothing Args: nothing globals: none
Usage: my ($incr_size, $error,$killed) = &$opt->Exec($timeout); Function: Copy the input record to the output Sleep a few seconds Arg: $timeout = The number of seconds after which a timeout is sent Return: $incr_size = The number of bytes added to the output file $error = An error code. If != 0, paraloop WILL BE TERMINATED - Generally marks the end of file $killed = A kill code 0: everything OK -1: killed by timeout 2: killed by TERM signal (kill, qdel, ...)
