Method Summary

String	backgroundExecuteAction(IPentahoSession userSession, IParameterProvider parameterProvider) NOTE: client code is responsible for making sure a job with the name identified by the parameter StandardSettings.SCHEDULE_NAME in the parameter provider does not already exist in the quartz scheduler.
IContentItem	getBackgroundContent(String contentGUID, IPentahoSession userSession) Gets the content generated by background execution
List	getBackgroundExecutedContentList(IPentahoSession userSession) Gets a list of content GUIDs of background executed jobs
IOutputHandler	getContentOutputHandler(String location, String fileName, String solutionName, IPentahoSession userSession, IParameterProvider parameterProvider) Returns the output handler for content, specific to the implementation of the background execution helper.
IPentahoSession	getEffectiveUserSession(String user) When the job runs in background, gets the effective user session for the user executing the job
List<IJobDetail>	getScheduledAndExecutingBackgroundJobs(IPentahoSession userSession) Gets the list of items scheduled for background execution, and those currently executing
void	removeBackgroundExecutedContentForID(String contentGUID, IPentahoSession userSession) Removes the content generated by background execution
void	trackBackgroundExecution(IPentahoSession userSession, String GUID) This provides an entry point for tracking the created background execution task
