Class ConfigList

java.lang.Object

org.qbroker.monitor.ConfigList

public class ConfigList
extends java.lang.Object

ConfigList manages a list of configuration properties from a remote repository or a remote data source for generic purposes. It has a property monitor to watch the remote repository or the remote data source. Once the monitor detects any changes on the configuration, it will download or fetch the new version of the configuration that consists of configuration properties for all the objects in the list. For each object of the list, its configuration has two identifiers, a unique id to identify the item in the list and a unique name as the key for the object. ConfigList provides a set of methods to maintain and manage these configurations picked up from a remote repository or a remote data source.

One of the use cases is the support of external rulesets for message nodes.
