org.apache.hadoop.conf-Configured

---

org.apache.hadoop.conf中的最后一个类，也是这个包中以后用的最频繁的一个，Configurable算是肉体，Configuration算是灵魂吧

---

 package org.apache.hadoop.conf;

 /** Base class for things that may be configured with a {@link Configuration}. */
 public class Configured implements Configurable {

   private Configuration conf;

   /** Construct a Configured. */
   public Configured() {
     this(null);
   }

   /** Construct a Configured. */
   public Configured(Configuration conf) {
     setConf(conf);
   }

   // inherit javadoc
   public void setConf(Configuration conf) {
     this.conf = conf;
   }

   // inherit javadoc
   public Configuration getConf() {
     return conf;
   }

 }

---

整个代码没什么好解释的。

就一个//inherit javadoc让我顿了一下，后来知道了，是继承了接口的注释

  /** Set the configuration to be used by this object. */
   void setConf(Configuration conf);

   /** Return the configuration used by this object. */
   Configuration getConf();
