DESCRIPTION

A processor task based on this class process anything that can be divided into processing clusters. Each cluster is processed one by one by calling the process() method. A count is incremented at the end of each cluster. By default, a AnyEvent::Processor::Watcher is associated with the class, interrupting the processing each second for calling "process_message".

ATTRIBUTES

verbose

Verbose mode. In this mode an AnyEvent::Processor::Watcher is automatically created, with a 1s timeout, and action directly sent to this class. You can create your own watcher subclassing AnyEvent::Processor::Watcher.

watcher

An AnyEvent::Processor::Watcher.

count

Number of items which have been processed.

blocking

Is it a blocking task (not a task). False by default.

METHODS

run

Run the process.

start_process

Something to do at beginning of the process.

start_message

Something to say about the process. Called by default watcher when verbose mode is enabled. By default, just send to STDOUT 'Start process...'. Your class can display another message, or do something else, like sending an email, or a notification to a monitoring system like Nagios.

process

Process something and increment count. This method has to be surclassed by you class if you want to do someting else than incrementing the "count" attribute.

process_message

Say something about the process. Called by default watcher (verbose mode) each 1s. By default, just display the "count" value. Your processor can display something else than just the number of processing clusters already processed. If your processor monitor the temperature of your fridge, you can display it...

end_process

Do something at the end of the process.

end_message

Say something at the end of the process. Called by default watcher.
