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();
