Interface CatalogNodeList

All Superinterfaces:
AutoCloseable, Closeable, OsidList, OsidList
public interface CatalogNodeList extends OsidList

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

while (cnl.hasNext()) {
     CatalogNode node = cnl.getNextCatalogNode();
}
or 
while (cnl.hasNext()) {
     CatalogNode[] nodes = cnl.getNextCatalogNodes(cnl.available());
}

    • getNextCatalogNode

      CatalogNode getNextCatalogNode() throws OperationFailedException
      Gets the next CatalogNode in this list.
      Returns:
      the next CatalogNode in this list. The hasNext() method should be used to test that a next CatalogNode is available before calling this method.
      Throws:
      IllegalStateException - no more elements available in this list
      OperationFailedException - unable to complete request

      mandatory - This method must be implemented.

    • getNextCatalogNodes

      CatalogNode[] getNextCatalogNodes(long n) throws OperationFailedException
      Gets the next set of CatalogNode elements in this list which must be less than or equal to the number returned from available() .
      Parameters:
      n - the number of CatalogNode elements requested which should be less than or equal to available()
      Returns:
      an array of CatalogNode elements. The length of the array is less than or equal to the number specified.
      Throws:
      IllegalStateException - no more elements available in this list
      OperationFailedException - unable to complete request
      Compliance:
