Interface PriceList

All Superinterfaces:

java.lang.AutoCloseable, java.io.Closeable, OsidList

public interface PriceList
extends OsidList

Like all OsidLists, PriceList provides a means for accessing Price elements sequentially either one at a time or many at a time. Examples:

       
       
       while (pl.hasNext()) {
            Price price = pl.getNextPrice();
       }
       
                   
       
  

or

       
       
       while (pl.hasNext()) {
            Price[] prices = pl.getNextPrices(pl.available());
       }
