ZooKeeperSupportThriftClient (grizzly-thrift 1.3.15 API)

All Known Implementing Classes:

GrizzlyThriftClient
```
public interface ZooKeeperSupportThriftClient
```
The interface using the ZooKeeper for synchronizing thrift server list
Example of use: final GrizzlyThriftClientManager.Builder managerBuilder = new GrizzlyThriftClientManager.Builder(); // setup zookeeper server final ZooKeeperConfig zkConfig = ZooKeeperConfig.create("thrift-client-manager", DEFAULT_ZOOKEEPER_ADDRESS); zkConfig.setRootPath(ROOT); zkConfig.setConnectTimeoutInMillis(3000); zkConfig.setSessionTimeoutInMillis(30000); zkConfig.setCommitDelayTimeInSecs(2); managerBuilder.zooKeeperConfig(zkConfig); // create a thrift client manager final GrizzlyThriftClientManager manager = managerBuilder.build(); final GrizzlyThriftClient.Builder<String, String> thriftClientBuilder = manager.createThriftClientBuilder("user"); // setup thrift servers final Set<SocketAddress> thriftServers = new HashSet<SocketAddress>(); thriftServers.add(THRIFT_SERVER_ADDRESS1); thriftServers.add(THRIFT_SERVER_ADDRESS2); thriftClientBuilder.servers(thriftServers); // create a user thrift final GrizzlyThriftClient<String, String> thriftClient = thriftClientBuilder.build(); // ZooKeeperSupportThriftClient's basic operations if (thriftClient.isZooKeeperSupported()) { final String serverListPath = thriftClient.getZooKeeperServerListPath(); final String serverList = thriftClient.getCurrentServerListFromZooKeeper(); thriftClient.setCurrentServerListOfZooKeeper("localhost:11211,localhost:11212"); } // ... // clean manager.removeThriftClient("user"); manager.shutdown();

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method and Description
`void`	`addZooKeeperListener(BarrierListener listener)` Add the custom `BarrierListener` The given `listener` will be called after thrift client's default listener will be completed.
`String`	`getCurrentServerListFromZooKeeper()` Return the current thrift server list string from the ZooKeeper server
`String`	`getZooKeeperServerListPath()` Return the path of the thrift server list which has been registered in the ZooKeeper server
`boolean`	`isZooKeeperSupported()` Check if this thrift client supports the ZooKeeper for synchronizing the thrift server list
`void`	`removeZooKeeperListener(BarrierListener listener)` Remove the custom `BarrierListener` The given `listener` will be called after thrift client's default listener will be completed.
`boolean`	`setCurrentServerListOfZooKeeper(String thriftServerList)` Set the current thrift server list string with the given `thriftServerList`

- Method Detail
  - isZooKeeperSupported
```
boolean isZooKeeperSupported()
```
    Check if this thrift client supports the ZooKeeper for synchronizing the thrift server list
    
    Returns:
    
    true if this thrift client supports it
  - getZooKeeperServerListPath
```
String getZooKeeperServerListPath()
```
    Return the path of the thrift server list which has been registered in the ZooKeeper server
    
    Returns:
    
    the path of the thrift server list in the ZooKeeper server. "null" means this thrift client doesn't support the ZooKeeper or this thrift client is not started yet
  - getCurrentServerListFromZooKeeper
```
String getCurrentServerListFromZooKeeper()
```
    Return the current thrift server list string from the ZooKeeper server
    
    Returns:
    
    the current server list string
  - setCurrentServerListOfZooKeeper
```
boolean setCurrentServerListOfZooKeeper(String thriftServerList)
```
    Set the current thrift server list string with the given thriftServerList
    thriftServerList could be comma separated host:port pairs, each corresponding to a thrift server. e.g. "127.0.0.1:3000,127.0.0.1:3001,127.0.0.1:3002" Be careful that this operation will propagate thriftServerList to thrift clients which has joinned the same thrift client name(scope) because the thrift server list of ZooKeeper server will be changed.
    
    Parameters:
    
    thriftServerList - the thrift server list string
    
    Returns:
    
    true if this thrift server list is set successfully
  - addZooKeeperListener
```
void addZooKeeperListener(BarrierListener listener)
```
    Add the custom BarrierListener The given listener will be called after thrift client's default listener will be completed. BarrierListener.onInit(java.lang.String, java.lang.String, byte[]) will be called when this thrift client will be registered in the ZooKeeper. BarrierListener.onCommit(java.lang.String, java.lang.String, byte[]) will be called when this thrift client's server list will be changed in the ZooKeeper. BarrierListener.onDestroy(java.lang.String) will be called when this thrift client will be unregistered in the ZooKeeper.
    
    Parameters:
    
    listener - the custom listener
  - removeZooKeeperListener
```
void removeZooKeeperListener(BarrierListener listener)
```
    Remove the custom BarrierListener The given listener will be called after thrift client's default listener will be completed. BarrierListener.onInit(java.lang.String, java.lang.String, byte[]) will be called when this thrift client will be registered in the ZooKeeper. BarrierListener.onCommit(java.lang.String, java.lang.String, byte[]) will be called when this thrift client's server list will be changed in the ZooKeeper. BarrierListener.onDestroy(java.lang.String) will be called when this thrift client will be unregistered in the ZooKeeper.
    
    Parameters:
    
    listener - the custom listener which was given by addZooKeeperListener(org.glassfish.grizzly.thrift.client.zookeeper.BarrierListener)
