public interface ProcessNodeList extends OsidList
Like all OsidLists,
ProcessNodeList
provides a means for accessing ProcessNode
elements
sequentially either one at a time or many at a time. Examples:
while (pnl.hasNext()) { ProcessNode node = pnl.getNextProcessNode(); }or
while (pnl.hasNext()) { ProcessNode[] nodes = pnl.getNextProcessNodes(pnl.available()); }
Modifier and Type | Method and Description |

ProcessNode |
getNextProcessNode()
Gets the next
ProcessNode in this list. |
ProcessNode[] |
getNextProcessNodes(long n)
Gets the next set of
ProcessNode elements in this list
which must be less than or equal to the return from
available(). |
ProcessNode getNextProcessNode() throws OperationFailedException
ProcessNode

hasNext()
method should be used to test that a next
