Direct Known Subclasses:

PlainIterativeActivityRun, SearchBasedActivityRun

public abstract class IterativeActivityRun<I,WD extends WorkDefinition,AH extends ActivityHandler<WD,AH>,WS extends AbstractActivityWorkStateType>
extends LocalActivityRun<WD,AH,WS>
implements ExecutionSupport, IterativeActivityRunSpecifics

Represents a run of an iterative activity: either plain iterative one or search-based one. Responsibilities at this level of abstraction: 1. Orchestrates the basic run cycle - see runLocally(OperationResult): a. calls before/after execution "hook" methods + the main execution routine, b. generates the execution result based on kind(s) of error(s) encountered. 2. Orchestrates the basic bucket execution cycle - see processOrAnalyzeOrSkipSingleBucket(OperationResult): a. item source preparation, b. before/after bucket execution "hook" methods, along with main iterateOverItemsInBucket(OperationResult) method, c. sets up and winds down the coordinator,

Field Detail

bucket

protected WorkBucketType bucket

Current bucket that is being processed. It is used to narrow the search query for search-based activities.

coordinator

protected ProcessingCoordinator<I> coordinator

Schedules individual items for processing by worker threads (if running in multiple threads). Re-created for each individual bucket.

errorState

@NotNull
protected final @NotNull ErrorState errorState

Error state. In particular, should we stop immediately because of a fatal exception? TODO rethink this

transientRunStatistics

@NotNull
protected final @NotNull TransientActivityRunStatistics transientRunStatistics

Maintains selected statistical information related to processing items in the current run. It is like a simplified version of ActivityItemProcessingStatistics that cover all the runs (and sometimes all the realizations) of an activity.

beans

@NotNull
protected final @NotNull CommonTaskBeans beans

Useful Spring beans.

Constructor Detail

IterativeActivityRun

public IterativeActivityRun(@NotNull
                            @NotNull ActivityRunInstantiationContext<WD,AH> context,
                            @NotNull
                            @NotNull String shortName)

Method Detail

runLocally

@NotNull
protected final @NotNull ActivityRunResult runLocally(OperationResult result)
                                               throws ActivityRunException,
                                                      CommonException

Specified by:

runLocally in class LocalActivityRun<WD extends WorkDefinition,AH extends ActivityHandler<WD,AH>,WS extends AbstractActivityWorkStateType>

Throws:

ActivityRunException

CommonException

prepareItemSourceForCurrentBucket

protected abstract void prepareItemSourceForCurrentBucket(OperationResult result)
                                                   throws ActivityRunException,
                                                          CommonException

Prepares the item source. E.g. for search-iterative tasks we prepare object type, query, and options here. Iterative activities delegate this method fully to the plugin. However, search-based activities provide their own default implementation.

Throws:

ActivityRunException

CommonException

isInRepository

protected abstract boolean isInRepository(OperationResult result)
                                   throws ActivityRunException,
                                          CommonException

Do we execute over items in repository? (Maybe the name should be changed.)

Throws:

ActivityRunException

CommonException

determineOverallSize

@Nullable
public @Nullable Integer determineOverallSize(OperationResult result)
                                       throws CommonException,
                                              ActivityRunException

Determines expected progress (overall size) for the activity. E.g. for search-based activities we count the objects here (overall).

Returns:

null if no value could be determined or is not applicable

Throws:

CommonException

ActivityRunException

determineCurrentBucketSize

@Nullable
public @Nullable Integer determineCurrentBucketSize(OperationResult result)
                                             throws CommonException

Determines the current bucket size. E.g. for search-based activities we count the objects here (in current bucket).

Returns:

null if no value could be determined or is not applicable

Throws:

CommonException

iterateOverItemsInBucket

protected abstract void iterateOverItemsInBucket(OperationResult result)
                                          throws CommonException

Starts the item source (e.g. `searchObjectsIterative` call or `synchronize` call) and begins processing items generated by it. Returns when the source finishes. For example: - for search-based tasks, this call returns immediately after the iterative search is over; - for live sync task, this returns after all changes were fetched and acknowledged, and the resulting token was written; - for async update task, this returns also after all changes were fetched and acknowledged and confirmed to the source.

Throws:

CommonException

getStartTimeMillis

public final long getStartTimeMillis()

isMultithreaded

public final ErrorHandlingStrategyExecutor.FollowUpAction handleError(@NotNull
                                                                      @NotNull OperationResultStatus status,
                                                                      @NotNull

updateStatistics

public void updateStatistics(boolean updateThreadLocalStatistics,
                             OperationResult result)
                      throws SchemaException,
                             ObjectNotFoundException

Updates statistics in the coordinator task (including TL if it's safe to do so). If needed, also updates the statistics in the repository. Statistics updated in the task: - task.operationStats, - progress (both activity-based and legacy), - activity statistics: items, synchronization, actions executed, bucketing operations Note that using modifyObjectDynamically would be perhaps better, but the current use of last update timestamp ensures that there will not be concurrent updates of the coordinator coming from its worker threads.

Throws:

SchemaException

ObjectNotFoundException
