java.lang.Object
  org.exist.storage.XQueryMonitor

public class XQueryMonitor

extends java.lang.Object

Class to keep track of all running queries in a database instance. The main purpose of this class is to signal running queries that the database is going to shut down. This is done through the XQueryWatchDog registered by each query. It is up to the query to check the watchdog's state. If it simply ignores the terminate signal, it will be killed after the shutdown timeout is reached.
