io.netty.resolver.dns.DnsCache

使用DnsCache的程序包

程序包	说明
io.netty.resolver.dns	An alternative to Java's built-in domain name lookup mechanism that resolves a domain name asynchronously, which supports the queries of an arbitrary DNS record type as well.

io.netty.resolver.dns中DnsCache的使用

实现DnsCache的io.netty.resolver.dns中的类

限定符和类型	类和说明
class	DefaultDnsCache Default implementation of DnsCache, backed by a ConcurrentMap.
class	NoopDnsCache A noop DNS cache that actually never caches anything.

返回DnsCache的io.netty.resolver.dns中的方法

限定符和类型	方法和说明
DnsCache	DnsNameResolver.resolveCache() Returns the resolution cache.

参数类型为DnsCache的io.netty.resolver.dns中的方法

限定符和类型	方法和说明
DnsNameResolverBuilder	DnsNameResolverBuilder.authoritativeDnsServerCache(DnsCache authoritativeDnsServerCache) 已过时。 Use DnsNameResolverBuilder.authoritativeDnsServerCache(AuthoritativeDnsServerCache)
protected void	DnsNameResolver.doResolve(java.lang.String inetHost, DnsRecord[] additionals, Promise<java.net.InetAddress> promise, DnsCache resolveCache) Hook designed for extensibility so one can pass a different cache on each resolution attempt instead of using the global one.
protected void	DnsNameResolver.doResolveAll(java.lang.String inetHost, DnsRecord[] additionals, Promise<java.util.List<java.net.InetAddress>> promise, DnsCache resolveCache) Hook designed for extensibility so one can pass a different cache on each resolution attempt instead of using the global one.
DnsNameResolverBuilder	DnsNameResolverBuilder.resolveCache(DnsCache resolveCache) Sets the cache for resolution results.

参数类型为DnsCache的io.netty.resolver.dns中的构造器

构造器和说明
DnsNameResolver(EventLoop eventLoop, ChannelFactory<? extends DatagramChannel> channelFactory, DnsCache resolveCache, AuthoritativeDnsServerCache authoritativeDnsServerCache, DnsQueryLifecycleObserverFactory dnsQueryLifecycleObserverFactory, long queryTimeoutMillis, ResolvedAddressTypes resolvedAddressTypes, boolean recursionDesired, int maxQueriesPerResolve, boolean traceEnabled, int maxPayloadSize, boolean optResourceEnabled, HostsFileEntriesResolver hostsFileEntriesResolver, DnsServerAddressStreamProvider dnsServerAddressStreamProvider, java.lang.String[] searchDomains, int ndots, boolean decodeIdn) 已过时。 Use DnsNameResolverBuilder.
