- Type Parameters:
T
- the type to be cached, typically either IPAddressString or HostName
- All Implemented Interfaces:
java.io.Serializable

public abstract static class AddressNetwork.HostIdentifierStringGenerator<T extends HostIdentifierString> extends java.lang.Object implements java.io.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.
