                                 @NotNull Task rootTask,
                                 @NotNull

Method Detail

recordLocalRunStart

public void recordLocalRunStart(@NotNull
                                @NotNull LocalActivityRun<?,?,?> run,
                                @NotNull
                                @NotNull OperationResult result)
                         throws ActivityRunException

Records the start of local activity run in the tree overview.

Throws:

ActivityRunException

recordDistributingActivityRealizationStart

public void recordDistributingActivityRealizationStart(@NotNull
                                                       @NotNull DistributingActivityRun<?,?,?> run,
                                                       @NotNull
                                                       @NotNull OperationResult result)
                                                throws ActivityRunException

Records the start of distributing (coordinator) activity realization (NOT run). It sets the fields that are not set by workers in their local runs.

Throws:

ActivityRunException

recordChildren

public void recordChildren(@NotNull
                           @NotNull LocalActivityRun<?,?,?> run,
                           List<Activity<?,?>> children,
                           @NotNull
                           @NotNull OperationResult result)
                    throws ActivityRunException

We need to know about all the children to be able to display the progress correctly. So this method updates the tree with the information about children of a composite activity. (Note: We only add records here. We assume that no children are ever deleted.)

Throws:

ActivityRunException

recordLocalRunFinish

public void recordLocalRunFinish(@NotNull
                                 @NotNull LocalActivityRun<?,?,?> run,
                                 @Nullable
                                 @Nullable ActivityRunResult runResult,
                                 @NotNull
                                 @NotNull OperationResult result)
                          throws ActivityRunException

Records the finish of a local activity run. Note that run result can be null only in the case of (very rare) uncaught exception.

Throws:

ActivityRunException

recordDistributingActivityRealizationFinish

public void recordDistributingActivityRealizationFinish(@NotNull
                                                        @NotNull DistributingActivityRun<?,?,?> run,
                                                        @NotNull
                                                        @NotNull ActivityRunResult runResult,
                                                        @NotNull
                                                        @NotNull OperationResult result)
                                                 throws ActivityRunException

Records the finish of distributing (coordinator) activity realization (NOT run). It sets the fields that are not set by workers in their local runs.

Throws:

ActivityRunException

recordTaskDead

public void recordTaskDead(@NotNull
                           @NotNull Task task,
                           @NotNull
                           @NotNull OperationResult result)
                    throws SchemaException,
                           ObjectNotFoundException

Called when a task was found dead. Updates the execution state (in the future we plan also to update the progress).

Throws:

SchemaException

ObjectNotFoundException

updateBucketAndItemProgress

public void updateBucketAndItemProgress(@NotNull
                                        @NotNull LocalActivityRun<?,?,?> run,
                                        @NotNull
                                        @NotNull BucketProgressOverviewType bucketProgress,
                                        @NotNull
                                        @NotNull OperationResult result)
                                 throws ActivityRunException

Updates bucket (and item) progress information in the activity tree. Also clears the "stalled since" flag. Note that there can be a race condition when updating buckets. If an update that was generated earlier (containing smaller # of completed buckets) is applied after an update generated later (larger # of completed buckets), incorrect results may be stored in the overview. Therefore we use a hack with isBefore(BucketProgressOverviewType, BucketProgressOverviewType) method.

Throws:

ActivityRunException

updateItemProgressIfTimePassed

public void updateItemProgressIfTimePassed(@NotNull
                                           @NotNull LocalActivityRun<?,?,?> run,
                                           long interval,
                                           OperationResult result)
                                    throws SchemaException,
                                           ObjectNotFoundException

Assumes that the activity run is still in progress. (I.e. also clear the "stalled since" flag.)

Throws:

SchemaException

ObjectNotFoundException

markTaskStalled

public void markTaskStalled(@NotNull
                            @NotNull String taskOid,
                            long stalledSince,
                            OperationResult result)
                     throws ObjectNotFoundException,
                            SchemaException
