public EventQueue(int maxTasks,
 boolean preallocate)

public void queue(Method method,
 Object callerInstance,
 int priority,
 Object... args)

Deprecated.

Creates a new ReflectTask instance and adds it to the event queue using queue(Task).

• ReflectTask(Method, Object, Object[], int)

queue

public void queue(Consumer<Object[]> handler,
 int priority,
 Object... args)

Deprecated.

Creates a new LambdaTask instance and adds it to the event queue using queue(Task).

See Also:

• queue(Task)
• LambdaTask(Consumer, Object[], int)

getNextTask

protected Task getNextTask()

Deprecated.

execute

public void execute()

Deprecated.

Executes the Task with the highest priority. If no task is available, this is a no-op.

executeBlocking

public void executeBlocking()

Blocks the thread until a task to execute becomes available, then executes it.

waitForTask

public void waitForTask()

Deprecated.

Blocks the thread until a task to execute becomes available.

clearTasks

public void clearTasks()

Deprecated.

Removes all queued tasks from the event queue.
