inet.ipaddr

Class AddressNetwork.HostIdentifierStringGenerator<T extends HostIdentifierString>

java.lang.Object

inet.ipaddr.AddressNetwork.HostIdentifierStringGenerator<T>

Type Parameters:

T - the type to be cached, typically either IPAddressString or HostName

All Implemented Interfaces:

Serializable

Direct Known Subclasses:

IPAddressNetwork.HostNameGenerator, IPAddressNetwork.IPAddressStringGenerator

Enclosing class:

AddressNetwork<S extends AddressSegment>

public abstract static class AddressNetwork.HostIdentifierStringGenerator<T extends HostIdentifierString>
extends Object
implements Serializable

Generates and caches HostIdentifierString instances. Choose a map of your choice to implement a cache of address string identifiers.

You choose the map of your choice to be the backing map for the cache. For example, for thread-safe access to the cache, ConcurrentHashMap is a good choice. For maps of bounded size, LinkedHashMap provides the removeEldestEntry method to override to implement LRU or other eviction mechanisms.
