Interface BusinessNodeList

All Superinterfaces:

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

public interface BusinessNodeList
extends OsidList

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

       
       
       while (bnl.hasNext()) {
            BusinessNode node = bnl.getNextBusinessNode();
       }
       
                   
       
  

or

       
       
       while (bnl.hasNext()) {
            BusinessNode[] nodes = bnl.getNextBusinessNodes(bnl.available());
       }
