Interface TypeList

All Superinterfaces:

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

public interface TypeList
extends OsidList

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

       
       
       while (tl.hasNext()) {
            Type type = tl.getNextType();
       }
       
                   
       
  

or

       
       
       while (tl.hasNext()) {
            Type[] types = tl.getNextTypes(tl.available());
       }
