Parameters:
zone - DNS zone
Parameters:
server - the server to remove |
| getBestGuess | | Server getBestGuess(String zone, Hashtable<Server, ?> serversToIgnore)(Code) | | Returns the best guess about that DNS server should be chosen to send the
request concerning the particular DNS zone.
Parameters:
zone - the name of DNS zone best guess - a SList.Server object;null if the information is not found |

instance of SList |
| getServerByIP | | Server getServerByIP(String zone, String ip, int port)(Code) | |
Parameters:

| getServerByName | | Server getServerByName(String zone, String name, int port)(Code) | |
Parameters:
zone - the name DNS zone
Parameters:
srvName - the name of the server
Parameters:
srvPort - the port of the server Server object with specified attributes |
| getServerByServer | | Server getServerByServer(String zone, Server server)(Code) | |
Parameters:
zone - the name of DNS zone to query SLIST with
Parameters:
server - the server to compare with first Server object from SLIST that equals tospecified server in terms of equals() method;null if not found.
See Also: SList.Server.equals(SList.Server) |
| getServersByName | | Enumeration<Server> getServersByName(String name)(Code) | | Returns all occurrences of server with specified
Parameters:
name - hostname found server object or null if not found |
| hasServer | | boolean hasServer(String zone, Server server)(Code) | |
Parameters:
zone - the name of zone
Parameters:
server - DNS server true if SList has information about specifiedserver & zone combination; false otherwise |
| hasServer | | boolean hasServer(String hostname)(Code) | | Checks if given server is present in the internal list of known servers.
Parameters:
hostname - host name of server true or false |
| setServerIP | | void setServerIP(String hostname, String newIP)(Code) | | Add IP information of server in list. Affects only servers with IP set to
null.

| updateEntry | | void updateEntry(String zone, Server server, int responseTime)(Code) | | Updates existent SLIST entry or creates a new one. S-List will be sorted
according the response time. Entries with bigger response will be placed
father from the beginning of the list.
