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." );
       }
    }
 }
