public interface GraphList extends OsidList
Like all OsidLists,
GraphList
provides a
means for accessing Graph
elements sequentially either one
at a time or many at a time. Examples:
while (gl.hasNext()) { Graph graph = gl.getNextGraph(); }or
while (gl.hasNext()) { Graph[] graphs = gl.getNextGraphs(gl.available()); }
Modifier and Type | Method and Description |
---|---|
Graph |
getNextGraph()
Gets the next
Graph in this list. |
Graph[] |
getNextGraphs(long n)
Gets the next set of
Graph elements in this list. |
Graph getNextGraph() throws OperationFailedException
Graph
in this list. Graph
in this list. The
hasNext()
method should be used to test that a next
Graph
is available before calling this method.IllegalStateException

- This method must be implemented. Graph[] getNextGraphs(long n) throws OperationFailedException
Graph
elements in this list. The
specified amount must be less than or equal to the return from
available().
n
- the number of Graph
elements requested which
must be less than or equal to available()
Graph
elements.
The
length of the array is less than or equal to the number
specified.IllegalStateException
