Description

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

                     
                     
                     while (enl.hasNext()) {
                          EngineNode node = enl.getNextEngineNode();
                     }
                     
                                 
                     
                
or
                     
                     
                     while (enl.hasNext()) {
                          EngineNode[] nodes = enl.getNextEngineNodes(enl.available());
                     }
                     
                                 
                     
                
MethodgetNextEngineNode
Description

Gets the next EngineNode in this list.

Returnosid.search.EngineNodethe next EngineNode in this list. The hasNext() method should be used to test that a next EngineNode is available before calling this method.
