Method Detail

process

public <R,E extends Exception> Cancellable process(Executable<R,E> task,
                                                   Continuation<R,E> 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.

Specified by:

process in interface Processor

Parameters:

task - The task to run on the processing thread

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

process

public <R,E extends Exception> Cancellable process(Executable<R,E> task,
                                                   Continuation<R,E> command,
                                                   int priority,
                                                   SelectorManager selector,
                                                   TimeSource ts,
                                                   LogManager log)

Description copied from interface: Processor

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. Passes a priority that will be respected if possible.

Specified by:

process in interface Processor

Parameters:

task - The task to run on the processing thread

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

priority - lower number is higher priority, 0 is default priority, and negative numbers are high priority

processBlockingIO

public Cancellable processBlockingIO(WorkRequest workRequest)

Description copied from interface: Processor

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

Specified by:

processBlockingIO in interface Processor

getQueue

public Queue<ProcessingRequest> getQueue()

destroy

public void destroy()

Description copied from interface: Processor

Shuts down the processing thread.

Specified by:

destroy in interface Destructable

Specified by:

destroy in interface Processor

getIOQueue

public WorkQueue getIOQueue()

main

public static void main(String[] args)
                 throws Exception

This is a test to make sure the order is correct.

Throws:

Exception
