Interface Computation

All Superinterfaces:

java.lang.Runnable

All Known Implementing Classes:

FactorialComputation, ParticleComputation, ParticleComputation, ParticleComputation, PingPongComputation

public interface Computation
extends java.lang.Runnable

Computation is the interface to be implemented by a class that will be instantiated by the SWC2 system in order to generate WorkUnit's and collect ResultUnit's.

The implementing class is also required to define the Runnable.run() method, which will be called (potentially in a separate thread) to do all the necessary work by the computation.

Method Detail

loadConfiguration

void loadConfiguration(java.util.Map config,
                       WorkQueueAccess wqa,
                       java.io.OutputStream os)
                       throws java.lang.Exception

Invoked by the SWC2 system in order to initialize the computation with the user supplied parameters.

Parameters:

config - The key/value pairs passed as initialization values for the computation.

wqa - The object through which the computation will submit work units and collect result units.

os - An output stream opened by the swc2 system, to be used by the computation for any output.

Throws:

java.lang.Exception - Any exception during initialization will caught by the swc2 system and the computation will be terminated.
