Interface Cursor<T>
- Type Parameters:
T
-
- All Superinterfaces:
AutoCloseable
,Closeable
,CloseableIterator<T>
,Iterator<T>
- All Known Implementing Classes:
ConvertingCursor
,KeyBoundCursor
,ScanCursor
Cursor abstraction to scan over the keyspace or elements within a data structure using a variant of a
SCAN
command.
Using a Java 8 java.util.stream.Stream
allows to apply additional
filters
and
limits
to the underlying Cursor
.
Make sure to close
the cursor when done as this allows implementations to clean up
any resources they need to keep open to iterate over elements (eg. by using a try-with-resource statement).
