Builder

protected Builder(PersistentTasks tasksInProgress)

Method Details

getLastAllocationId

public long getLastAllocationId()

setLastAllocationId

protected T setLastAllocationId(long currentId)

setLastAllocationId

protected T setLastAllocationId(ClusterState clusterState)

setTasks

protected <Params extends PersistentTaskParams> T setTasks(List<PersistentTasks.TaskBuilder<Params>> tasks)

addTask

public <Params extends PersistentTaskParams> T addTask(String taskId,
 String taskName,
 Params params,
 PersistentTasksCustomMetadata.Assignment assignment)

Adds a new task to the builder

After the task is added its id can be found by calling {getLastAllocationId()} method.

reassignTask

public T reassignTask(String taskId,
 PersistentTasksCustomMetadata.Assignment assignment)

Reassigns the task to another node

updateTaskState

public T updateTaskState(String taskId,
 PersistentTaskState taskState)

Updates the task state

removeTask

public T removeTask(String taskId)

Removes the task

hasTask

public boolean hasTask(String taskId)

Checks if the task is currently present in the list

hasTask

public boolean hasTask(String taskId,
 long allocationId)

Checks if the task is currently present in the list and has the right allocation id

isChanged

public boolean isChanged()

Returns true if any the task list was changed since the builder was created

build

public abstract PersistentTasks build()

buildAndUpdate

public final ClusterState buildAndUpdate(ClusterState currentState,
 ProjectId projectId)

doBuildAndUpdate

protected abstract ClusterState doBuildAndUpdate(ClusterState currentState,
 ProjectId projectId)
