Examples of java.io.Reader

java.io.Reader
Reader is an Abstract class for reading Character Streams. Subclasses of Reader must implement the methods read(char[], int, int) and close(). @see Writer

          +" cost-sensitive metaschemes such as"
          +" weka.classifiers.meta.CostSensitiveClassifier or"
          +" weka.classifiers.meta.MetaCost");


      Reader costReader = null;
