示例1: delete

import org.apache.zookeeper.proto.DeleteRequest; //导入方法依赖的package包/类
/**
 * Delete the node with the given path. The call will succeed if such a node
 * exists, and the given version matches the node's version (if the given
 * version is -1, it matches any node's versions).
 * <p>
 * A KeeperException with error code KeeperException.NoNode will be thrown
 * if the nodes does not exist.
 * <p>
 * A KeeperException with error code KeeperException.BadVersion will be
 * thrown if the given version does not match the node's version.
 * <p>
 * A KeeperException with error code KeeperException.NotEmpty will be thrown
 * if the node has children.
 * <p>
 * This operation, if successful, will trigger all the watches on the node
 * of the given path left by exists API calls, and the watches on the parent
 * node left by getChildren API calls.
 *
 * @param path
 *                the path of the node to be deleted.
 * @param version
 *                the expected node version.
 * @throws InterruptedException IF the server transaction is interrupted
 * @throws KeeperException If the server signals an error with a non-zero
 *   return code.
 * @throws IllegalArgumentException if an invalid path is specified

    // specifically - root cannot be deleted
    // I think this makes sense even in chroot case.
    if (clientPath.equals("/")) {
        // a bit of a hack, but delete(/) will never succeed and ensures
        // that the same semantics are maintained
