reschedule

<T> void reschedule(SchedulableInstance<T> schedulableInstance)

Update an existing execution with a new execution-time and new task-data. If the execution does not exist or if it is currently running, an exception is thrown.

Parameters:

schedulableInstance - the updated instance

cancel

void cancel(TaskInstanceId taskInstanceId)

Removes/Cancels an execution.

Parameters:

taskInstanceId -

fetchScheduledExecutions

void fetchScheduledExecutions(Consumer<ScheduledExecution<Object>> consumer)

Gets all scheduled executions and supplies them to the provided Consumer. A Consumer is used to avoid forcing the SchedulerClient to load all executions in memory. Currently running executions are not returned.

Parameters:

consumer - Consumer for the executions

fetchScheduledExecutions

void fetchScheduledExecutions(ScheduledExecutionsFilter filter,
 Consumer<ScheduledExecution<Object>> consumer)

getScheduledExecutions

default List<ScheduledExecution<Object>> getScheduledExecutions()

See Also:

• fetchScheduledExecutions(Consumer)

getScheduledExecutions

default List<ScheduledExecution<Object>> getScheduledExecutions(ScheduledExecutionsFilter filter)

See Also:

• fetchScheduledExecutions(Consumer)

fetchScheduledExecutionsForTask

<T> void fetchScheduledExecutionsForTask(String taskName,
 Class<T> dataClass,
 Consumer<ScheduledExecution<T>> consumer)

Gets all scheduled executions for a task and supplies them to the provided Consumer. A Consumer is used to avoid forcing the SchedulerClient to load all executions in memory. Currently running executions are not returned.

Parameters:

taskName - the name of the task to get scheduled-executions for

dataClass - the task data-class the data will be serialized and cast to

consumer - Consumer for the executions

fetchScheduledExecutionsForTask

<T> void fetchScheduledExecutionsForTask(String taskName,
 Class<T> dataClass,
 ScheduledExecutionsFilter filter,
 Consumer<ScheduledExecution<T>> consumer)

getScheduledExecutionsForTask

getScheduledExecutionsForTask

default <T> List<ScheduledExecution<T>> getScheduledExecutionsForTask(String taskName,
 Class<T> dataClass,
 ScheduledExecutionsFilter filter)

See Also:

• fetchScheduledExecutionsForTask(String, Class, Consumer)

getScheduledExecution

Optional<ScheduledExecution<Object>> getScheduledExecution(TaskInstanceId taskInstanceId)

Gets the details for a specific scheduled execution. Currently running executions are also returned.

Parameters:

taskInstanceId -

Returns:

Optional.empty() if no matching execution found
