Class NodeSnapshot

java.lang.Object

com.aoindustries.noc.monitor.common.NodeSnapshot

All Implemented Interfaces:

Serializable

public final class NodeSnapshot
extends Object
implements Serializable

Gets a serializable snapshot of a node, including all of its children. Nodes themselves are Remote objects. Thus any iteration over them incurs may round-trips to the RMI server. This snapshot mechanism allows calling code to get the current state of the node tree with a single RMI call.
