weka.core.Utils.forName()方法的使用及代码示例
本文整理了Java中weka.core.Utils.forName()方法的一些代码示例，展示了Utils.forName()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Utils.forName()方法的具体详情如下：
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);代码示例
