Interface | osid.topology.GraphNodeList | ||
---|---|---|---|
Implements | osid.OsidList | ||
Description |
Like all while (gnl.hasNext()) { GraphNode node = gnl.getNextGraphNode(); }or while (gnl.hasNext()) { GraphNode[] nodes = gnl.getNextGraphNodes(gnl.available()); } | ||
Method | getNextGraphNode | ||
Description |
Gets the next | ||
Return | osid.topology.GraphNode | the next GraphNode in this list. The hasNext()
method should be used to test that a next GraphNode is
available before calling this method. | |
Errors | ILLEGAL_STATE | no more elements available in this list | |
OPERATION_FAILED | unable to complete request | ||
Compliance | mandatory | This method must be implemented. | |
Method | getNextGraphNodes | ||
Description |

Return | osid.topology.GraphNode[] | an array of GraphNode elements. The length of
the array is less than or equal to the number specified. | |
Errors | ILLEGAL_STATE | no more elements available in this list | |
