Examples of WindowNode

org.drools.core.reteoo.WindowNode
WindowNodes are nodes in the Rete network used to manage windows. They support multiple types of windows, like sliding windows, tumbling windows, etc.
This class must act as a lock-gate for all working memory actions on it and propagated down the network in this branch, as there can be concurrent threads propagating events and expiring events working on this node at the same time. It requires it to be thread safe.
