方法名:getConfig

ZooKeeper.getConfig介绍

[英]The asynchronous version of getConfig.
[中]getConfig的异步版本。

代码示例

代码示例来源:origin: apache/zookeeper

/**
 * The Asynchronous version of getConfig. 
 * 
 * @see #getData(String, boolean, Stat)
 */
public void getConfig(boolean watch, DataCallback cb, Object ctx) {
  getConfig(watch ? watchManager.defaultWatcher : null, cb, ctx);
}

代码示例来源:origin: apache/zookeeper

/**
 * Return the last committed configuration (as known to the server to which the client is connected)
 * and the stat of the configuration.
 * <p>
 * If the watch is true and the call is successful (no exception is
 * thrown), a watch will be left on the configuration node (ZooDefs.CONFIG_NODE). The watch
 * will be triggered by a successful reconfig operation
 * <p>
 * A KeeperException with error code KeeperException.NoNode will be thrown
 * if no node with the given path exists.
 *
 * @param watch whether need to watch this node
 * @param stat the stat of the configuration node ZooDefs.CONFIG_NODE
 * @return configuration data stored in ZooDefs.CONFIG_NODE
 * @throws KeeperException If the server signals an error with a non-zero error code
 * @throws InterruptedException If the server transaction is interrupted.

public byte[] getConfig(boolean watch, Stat stat)
    throws KeeperException, InterruptedException {
  return getConfig(watch ? watchManager.defaultWatcher : null, stat);
}
