Package org.opennars.entity

Class TaskLink

java.lang.Object

org.opennars.entity.Item<Task>

org.opennars.entity.TaskLink

All Implemented Interfaces:

Serializable, TLink<Task>

public class TaskLink
extends Item<Task>
implements TLink<Task>, Serializable

Reference to a Task.

The reason to separate a Task and a TaskLink is that the same Task can be linked from multiple Concepts, with different BudgetValue. TaskLinks are unique according to the Task they reference
