Interface OptionArrayable

  • All Superinterfaces:
    OptionModifiable
    All Known Implementing Classes:
    ArrayOption

    public interface OptionArrayable
    extends OptionModifiable
    If an option supports array registration and processing then it should implement this interface.

    For example, let's say we are implementing an integer array option class.

     public class MyIntArray extends ArrayOption implements OptionArrayable,
                                                            OptionModifiable {
        int values[];
    
        // rest of implementation goes here.
    
        public void modify(java.lang.String[] value) {
           try {
              int newValues[] = new int[ value.length ];
              for int( n = 0; n < value.length; n++ ) {
                 newValues[ n ] = Integer.parseInt( value[ n ] );
              }
              values[ n ] = newValues;
           }
           catch ( NumberFormatException e ) {
              throw new OptionModificationException( "Not a number." );
           }
        }
     }
