包路径：weka.core.Utils
类名称：Utils
方法名：forName

Utils.forName介绍

[英]Creates a new instance of an object given it's class name and (optional) arguments to pass to it's setOptions method. If the object implements OptionHandler and the options parameter is non-null, the object will have it's options set. Example use:

``

String classifierName = Utils.getOption('W', options); 
Classifier c = (Classifier)Utils.forName(Classifier.class, 
classifierName, 
options); 
setClassifier(c);

[中]在给定对象的类名和（可选）参数的情况下，创建对象的新实例，以传递给对象的setOptions方法。如果对象实现OptionHandler，并且options参数为非null，则对象将设置其选项。示例用法：
``

String classifierName = Utils.getOption('W', options); 
Classifier c = (Classifier)Utils.forName(Classifier.class, 
classifierName, 
options); 
setClassifier(c);
