com.storedobject.job.TaskExecutor

public class TaskExecutor
extends Object

TaskExecutor is responsible for scheduling and executing tasks at specific times. It supports adding, removing, and executing tasks at defined times with optional day-of-week filtering.
Tasks are executed in virtual threads and are managed on a periodic schedule.
This class runs a scheduler that executes tasks every minute based on their defined execution time and days of the week. The scheduler uses a virtual thread to run tasks to optimize resource utilization.

Method Details

shutdown

public static void shutdown()

Shuts down the executor service used by the TaskExecutor. This method is typically invoked to cleanly terminate the executor, ensuring that no new tasks are accepted and that existing tasks in the queue are processed.

addTask

public static void addTask(Runnable runnable,
 int minutesOfDay,
 int daysOfTheWeek)

Adds a task to be executed at a specific time of the day on specified days of the week. The task will be synchronized and stored for execution later.

Parameters:

runnable - The task to be executed, represented as a Runnable instance.

minutesOfDay - The time of the day in minutes after midnight at which the task should be executed. For example, 0 represents midnight, 720 represents 12:00 PM.

daysOfTheWeek - A bitmask representing the days of the week on which the task should be executed. The 7 least significant bits correspond to Sunday through Saturday (e.g., 0b1111111 for all days, 0b0000001 for Sunday).

addTask

public static void addTask(Runnable runnable,
 int minutesOfDay)

Adds a task that will be executed at the specified time of day every day.

Parameters:

runnable - The task to execute, represented as a Runnable.

minutesOfDay - The time of day at which the task should execute, specified as the number of minutes past midnight.

removeTask

public static void removeTask(Runnable runnable)

Removes a task from the list of scheduled tasks based on the provided runnable instance. The removal is performed within a synchronized block to ensure thread safety.

Parameters:

runnable - The runnable instance of the task to be removed.
