Class ActivityTreeUtil

java.lang.Object

com.evolveum.midpoint.schema.util.task.ActivityTreeUtil

public class ActivityTreeUtil
extends Object

Utility methods for navigating throughout activity trees, potentially distributed throughout a task tree. (There are also variants that traverse only local activities in a task.)

static void	processLocalStates(@NotNull TaskType task, @NotNull ActivityTreeUtil.LocalActivityStateProcessor processor)	Processes local activity state objects using the same rules as in transformLocalStates(TaskType, LocalActivityStateTransformer) (TaskType, ActivityStateTransformer)}: all states are treated the same.
static void	processStates(@NotNull TaskType rootTask, @NotNull TaskResolver resolver, @NotNull ActivityTreeUtil.ActivityStateProcessor processor)	Processes activity state objects using the same rules as in transformStates(TaskType, TaskResolver, ActivityStateTransformer): delegation states are ignored, distribution states are considered, along with all their workers' states.
static @NotNull TreeNode<ActivityTreeUtil.ActivityStateInLocalContext>	toLocalStateTree(@NotNull TaskType task)	Creates a TreeNode of ActivityTreeUtil.ActivityStateInLocalContext objects for activities locally contained in the task.
static @NotNull TreeNode<ActivityTreeUtil.ActivityStateInContext>	toStateTree(@NotNull TaskType rootTask, @NotNull TaskResolver resolver)	Special case of transformStates(TaskType, TaskResolver, ActivityStateTransformer): creates a TreeNode of ActivityTreeUtil.ActivityStateInContext objects.
static <X> @NotNull TreeNode<X>	transformLocalStates(@NotNull TaskType rootTask, @NotNull ActivityTreeUtil.LocalActivityStateTransformer<X> transformer)	Transforms task-local activity state objects into custom ones, organized into a tree.

Method Details

transformStates

@NotNull
public static <X> @NotNull TreeNode<X> transformStates(@NotNull
 @NotNull TaskType rootTask,
 @NotNull
 @NotNull TaskResolver resolver,
 @NotNull
 @NotNull ActivityTreeUtil.ActivityStateTransformer<X> transformer)

Transforms activity state objects into custom ones, organized into a tree. Delegation states are ignored. Distribution states are considered, and their workers' states are packed along them.

transformLocalStates

@NotNull
public static <X> @NotNull TreeNode<X> transformLocalStates(@NotNull
 @NotNull TaskType rootTask,
 @NotNull
 @NotNull ActivityTreeUtil.LocalActivityStateTransformer<X> transformer)

Transforms task-local activity state objects into custom ones, organized into a tree. Does not distinguish between local, delegated, and distributed states: all are treated the same.

processStates

public static void processStates(@NotNull
 @NotNull TaskType rootTask,
 @NotNull
 @NotNull TaskResolver resolver,
 @NotNull
 @NotNull ActivityTreeUtil.ActivityStateProcessor processor)

Processes activity state objects using the same rules as in transformStates(TaskType, TaskResolver, ActivityStateTransformer): delegation states are ignored, distribution states are considered, along with all their workers' states.

processLocalStates

public static void processLocalStates(@NotNull
 @NotNull TaskType task,
 @NotNull
 @NotNull ActivityTreeUtil.LocalActivityStateProcessor processor)

Processes local activity state objects using the same rules as in transformLocalStates(TaskType, LocalActivityStateTransformer) (TaskType, ActivityStateTransformer)}: all states are treated the same.

toStateTree

@NotNull
public static @NotNull TreeNode<ActivityTreeUtil.ActivityStateInContext> toStateTree(@NotNull
 @NotNull TaskType rootTask,
 @NotNull
 @NotNull TaskResolver resolver)

Special case of transformStates(TaskType, TaskResolver, ActivityStateTransformer): creates a TreeNode of ActivityTreeUtil.ActivityStateInContext objects.

toLocalStateTree

@NotNull
public static @NotNull TreeNode<ActivityTreeUtil.ActivityStateInLocalContext> toLocalStateTree(@NotNull
 @NotNull TaskType task)

Creates a TreeNode of ActivityTreeUtil.ActivityStateInLocalContext objects for activities locally contained in the task.

hasDelegatedActivity

public static boolean hasDelegatedActivity(TreeNode<ActivityTreeUtil.ActivityStateInContext> node)

We know this by comparing task OIDs (except for worker ones): all must be the same to be non-delegated.

getSubtasksForPath

@NotNull
public static @NotNull List<TaskType> getSubtasksForPath(TaskType task,
 ActivityPath activityPath,
 TaskResolver taskResolver)

getAllLocalStates

@NotNull
public static @NotNull List<ActivityStateType> getAllLocalStates(@NotNull
 @NotNull TaskActivityStateType taskActivityState)
