Interface PlanList

All Superinterfaces:

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

public interface PlanList
extends OsidList

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

       
       
       while (pl.hasNext()) {
            Plan plan = pl.getNextPlan();
       }
       
                   
       
  

or

       
       
       while (pl.hasNext()) {
            Plan[] plans = pl.getNextPlans(pl.available());
       }
