Description

Interface Summary

DNSToSwitchMapping	An interface that should be implemented to allow pluggable DNS-name/IP-address to RackID resolvers.
Node	The interface defines a node in a network topology.

Class Summary

CachedDNSToSwitchMapping	A cached implementation of DNSToSwitchMapping that takes an raw DNSToSwitchMapping and stores the resolved network location in a cache.
DNS	A class that provides direct and reverse lookup functionalities, allowing the querying of specific network interfaces or nameservers.
NetUtils
NetworkTopology	The class represents a cluster of computer with a tree hierarchical network topology.
NetworkTopologyWithNodeGroup	The class extends NetworkTopology to represents a cluster of computer with a 4-layers hierarchical network topology.
NodeBase	A base class that implements interface Node
ScriptBasedMapping	This class implements the DNSToSwitchMapping interface using a script configured via topology.script.file.name .
SocketInputStream	This implements an input stream that can have a timeout while reading.
SocketOutputStream	This implements an output stream that can have a timeout while writing.
SocksSocketFactory	Specialized SocketFactory to create sockets with a SOCKS proxy
StandardSocketFactory	Specialized SocketFactory to create sockets with a SOCKS proxy
