Interface SystemNodeList

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

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

while (snl.hasNext()) {
     SystemNode node = snl.getNextSystemNode();
}
or 
while (snl.hasNext()) {
     SystemNode[] nodes = snl.getNextSystemNodes(snl.available());
}

  • Method Details

    • getNextSystemNode

      SystemNode getNextSystemNode() throws OperationFailedException
      Gets the next SystemNode in this list.
      Returns:
      the next SystemNode in this list. The hasNext() method should be used to test that a next SystemNode 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.

    • getNextSystemNodes

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