Interface ActivityNodeList

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

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

while (anl.hasNext()) {
     ActivityNode node = anl.getNextActivityNode();
}
or 
while (anl.hasNext()) {
     ActivityNode[] nodes = anl.getNextActivityNodes(anl.available());
}

  • Method Details

    • getNextActivityNode

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

    • getNextActivityNodes

      ActivityNode[] getNextActivityNodes(long n) throws OperationFailedException
      Gets the next set of ActivityNode elements in this list. The specified amount must be less than or equal to the return from available() .
      Parameters:
      n - the number of ActivityNode elements requested which must be less than or equal to available()
      Returns:
      an array of ActivityNode 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:
      mandatory - This method must be implemented.
