示例1: pigToRuby
import org.jruby.Ruby; //导入方法依赖的package包/类
/**
* This is the method which provides conversion from Pig to Ruby. In this case, an
* instance of the Ruby runtime is necessary. This method provides the general detection
* of the type and then calls the more specific conversion methods.
*
* @param ruby the Ruby runtime to create objects in
* @param object the Pig object to convert to Ruby
* @return Ruby analogue of object
* @throws ExecException object is not a convertible Pig type
