示例1: each
import org.jruby.runtime.Block; //导入方法依赖的package包/类
/**
* This is an implementation of the each method which opens up the Enumerable interface,
* and makes it very convenient to iterate over the elements of a DataBag. Note that currently,
* due to a deficiency in JRuby, it is not possible to call each without a block given.
*
* @param context the context the method is being executed in
* @param block a block to call on the elements of the bag
* @return enumerator object if null block given, nil otherwise
*/
