Constructor Detail

SolutionProcessor

public SolutionProcessor(TaskAssigningRuntimeDelegate delegate,
                         Consumer<SolutionProcessor.Result> resultConsumer,
                         String targetUserId,
                         int publishWindowSize)

Parameters:

delegate - a TaskAssigningRuntimeDelegate instance for executing methods into the jBPM runtime.

resultConsumer - a consumer for processing the results.

targetUserId - a user identifier for using as the "on behalf of" user when interacting with the jBPM runtime.

publishWindowSize - Integer value > 0 that indicates the number of tasks to be published.

Method Detail

isProcessing

public boolean isProcessing()

Returns:

true if a solution is being processed at this time, false in any other case.

process

public void process(org.kie.server.services.taskassigning.core.model.TaskAssigningSolution solution)

This method is invoked from a different thread for doing the processing of a solution. If a solution is being processed an exception is thrown, so it's expected that any synchronization required between the isProcessing() and process() methods is performed by the caller. Since only one solution can be processed at time, the caller should typically execute in the following sequence. if (!solutionProcessor.isProcessing()) { solutionProcessor.process(solution); } else { //invoke at a later time. } A null value will throw an exception too.

Parameters:

solution - a solution to process.

destroy

public void destroy()

Overrides:

destroy in class RunnableBase

run

public void run()

doProcess

protected void doProcess(org.kie.server.services.taskassigning.core.model.TaskAssigningSolution solution)
