public interface Processor
extends Destructable

Provides a mechanism to do time consuming tasks off of FreePastry's selecto thread. Usually acquired by calling environment.getProcessor().

Method Summary

void	destroy() Shuts down the processing thread.
void	process(Executable task, Continuation command, SelectorManager selector, TimeSource ts, LogManager log) Schedules a job for processing on the dedicated processing thread.
void	processBlockingIO(WorkRequest request) Schedules a different type of task.

Method Detail

process

void process(Executable task,
             Continuation command,
             SelectorManager selector,
             TimeSource ts,
             LogManager log)

Schedules a job for processing on the dedicated processing thread. CPU intensive jobs, such as encryption, erasure encoding, or bloom filter creation should never be done in the context of the underlying node's thread, and should only be done via this method. The continuation will be called on the Selector thread.

Parameters:

task - The task to run on the processing thread

command - The command to return the result to once it's done

processBlockingIO

void processBlockingIO(WorkRequest request)

Schedules a different type of task. This thread is for doing Disk IO that is required to be blocking.

Parameters:

request -

destroy

void destroy()

Shuts down the processing thread.
