Class NodeLabelCache

java.lang.Object

hudson.slaves.ComputerListener

org.jvnet.hudson.plugins.platformlabeler.NodeLabelCache

All Implemented Interfaces:

ExtensionPoint

@Extension
public class NodeLabelCache
extends ComputerListener

A cache of Node labels.

While it would be nice to have a single implementation extending both FindLabels and ComputerListener, because Jenkins uses subclassing it is not easy to do so. Instead we provide a static cache which the LabelFinder in our package can read.
