Interface IStringCustomizer

public interface IStringCustomizer

This interface is used for displaying non-ASCII characters in EspressChart, e.g. Japaneses Characters. Implement this abstract class first, and pass it into the QbChart.setStringCustomizer() method.

Here is an example of an implementation.

  import quadbase.ChartAPI.*;
  import quadbase.util.*;

  // This is an example of a user implemented class of IStringCustomizer
  public class StrCustomizer implements IStringCustomizer
  {
        // default constructor
        public void StrCustomizer(){
        }

        // this is the only method that users need to implement
        // method takes in a String argument and returns a "formatted" String
        public String encodeString(String str){
                try {
                        // Convert this String into bytes according to the specified 
                        //  character encoding, storing the result into a new byte array.
                        byte[] bytes = str.getBytes("8859_1");

                        // Construct & return a new String by converting the specified 
                        //  array of bytes using the specified character encoding.
                        return new String(bytes, "SJIS");    
                } catch(java.io.UnsupportedEncodingException e){
                        ex.printStackTrace(); 
                }

                // return null if conversion is un-successful
                return null; 
        }
  }
