public interface FlowableTask<T extends Output>

Interface for tasks that orchestrate other tasks. Those tasks are handled by the Executor.

Method Details

getErrors

@PluginProperty
List<Task> getErrors()

tasksTree

GraphCluster tasksTree(Execution execution,
 TaskRun taskRun,
 List<String> parentValues)
                throws IllegalVariableEvaluationException

Create the topology representation of a flowable task.

A flowable task always contains subtask to it returns a cluster that displays the subtasks.

Throws:

IllegalVariableEvaluationException

allChildTasks

List<Task> allChildTasks()

Returns:

all child tasks including errors

childTasks

List<ResolvedTask> childTasks(RunContext runContext,
 TaskRun parentTaskRun)
                       throws IllegalVariableEvaluationException

Resolve child tasks of a flowable task.

For a normal flowable, it should be the list of its tasks, for an iterative flowable (such as EachSequential, ForEachItem, ...), it should be the list of its tasks for all iterations.

Throws:

IllegalVariableEvaluationException

resolveNexts

List<NextTaskRun> resolveNexts(RunContext runContext,
 Execution execution,
 TaskRun parentTaskRun)
                        throws IllegalVariableEvaluationException

Resolve next tasks to run for an execution.

For a normal flowable, it should be the subsequent task, for a parallel flowable (such as Parallel, ForEachItem, ...), it should be a list of the next subsequent tasks of the size of the concurrency of the task.

Throws:

IllegalVariableEvaluationException

resolveState

default Optional<State.Type> resolveState(RunContext runContext,
 Execution execution,
 TaskRun parentTaskRun)
                                   throws IllegalVariableEvaluationException

Resolve the state of a flowable task.

Throws:

IllegalVariableEvaluationException

outputs

default T outputs(RunContext runContext,
 Execution execution,
 TaskRun parentTaskRun)
           throws IllegalVariableEvaluationException

Throws:

IllegalVariableEvaluationException
