Class ProcessorTask

java.lang.Object
  uk.ac.soton.itinnovation.freefluo.core.task.AbstractTask
      uk.ac.soton.itinnovation.taverna.enactor.entities.ProcessorTask

All Implemented Interfaces:

IProcessorTask, uk.ac.soton.itinnovation.freefluo.core.event.RunEventSource, uk.ac.soton.itinnovation.freefluo.core.event.TaskStateListener, uk.ac.soton.itinnovation.freefluo.core.task.Task

public class ProcessorTask
extends uk.ac.soton.itinnovation.freefluo.core.task.AbstractTask
implements IProcessorTask

The superclass of all actual task implementations

Field Summary

static org.jdom.Namespace	provNS
static java.lang.String	REPORT_NAMESPACE
WorkflowInstance	workflowInstance

Constructor Summary

ProcessorTask(java.lang.String id, uk.ac.soton.itinnovation.freefluo.core.flow.Flow flow, Processor p, uk.ac.soton.itinnovation.freefluo.task.LogLevel l, java.lang.String userID, java.lang.String userCtx)

Method Summary

ProcessEvent[]	getEventList() Get the list of events thus far
org.jdom.Element	getFaultElement() If the processor invocation throws an exception causing it to fail, this class will populate an XML element with as much information as possible about the exception that was thrown.
Processor	getProcessor() Retrieves the XScufl Processor object for this task
org.jdom.Element	getProvenance() Retrieve provenance information for this task, concrete tasks should overide this method and provide this information as an XML JDOM element
java.util.List<java.lang.String>	getProvenanceList()
WorkflowInstance	getWorkflowInstance()
void	handleRun(uk.ac.soton.itinnovation.freefluo.core.event.RunEvent runEvents) Run the task
