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

 1 package org.apache.hadoop.conf;
 2 
 3 /** Base class for things that may be configured with a {@link Configuration}. */
 4 public class Configured implements Configurable {
 5 
 6   private Configuration conf;
 7 
 8   /** Construct a Configured. */
 9   public Configured() {
10     this(null);
11   }
12   
13   /** Construct a Configured. */
14   public Configured(Configuration conf) {
15     setConf(conf);
16   }
17 
18   // inherit javadoc
19   public void setConf(Configuration conf) {
20     this.conf = conf;
21   }
22 
23   // inherit javadoc
24   public Configuration getConf() {
25     return conf;
26   }
27 
28 }

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

1  /** Set the configuration to be used by this object. */
2   void setConf(Configuration conf);
3 
4   /** Return the configuration used by this object. */
5   Configuration getConf();
