NodeIdentifier identifies a database node. Can be created from a URL, by unparsing the hexadecimal id string @author jcheney
org.geotools.caching.spatialindex.NodeIdentifier
Instances of this class provide unique identifiers for nodes, and are used to store and retrieve nodes from their storage. Implementors must take care that instances have to be immutable. Nodes are basically identified by the region they represent. Kinds of nodes or kinds of storage may require to use other elements to identify nodes. Implementors must take care to override hashCode() and equals() accordingly. NodeIdentifier should not reference the node they identify, as they are likely to be used to passivate nodes in secondary storage. @author crousson @source $URL$
