Class PriorityRunnable

java.lang.Object

org.axonframework.common.util.PriorityRunnable

All Implemented Interfaces:

Comparable<PriorityTask>, Runnable, PriorityTask

public class PriorityRunnable
extends Object
implements Runnable, PriorityTask

A wrapper class of Runnables that adheres to a priority by implementing PriorityTask. Uses a combination of priority and index to compare between this and other priority task instances. A calculator (e.g.

invalid reference

org.axonframework.commandhandling.CommandPriorityCalculator

) defines the priority of the task. This task uses the index to differentiate between tasks with the same priority, ensuring the insert order is leading in those scenarios.

4.6.0
