| Class | Description |
|---|---|
| AbstractCursor<T> |
Base class to make
Cursors easier to implement. |
| AbstractPollingCursor<T> |
An extension of AbstractCursor that simplifies the mechanics of the
next()/hasNext() implementation to a simple method,
AbstractPollingCursor.poll(). |
| CursorIterator<T> |
Simple implementation of an Iterator that wraps a Cursor's data.
|
| Cursors |
Utility methods for cursors.
|
| GroupingCursor<C,E> |
Base class for cursors that group the output of another cursor.

Cursors (see Cursor) are basically
closeable iterators, used for accessing data sources. They also expose the
number of rows they will return, although it is not guaranteed that a cursor
can compute its length.
