@Deprecated(since="4.1.0")
public interface CloseableIteration<E,X extends Exception>
extends Iteration<E,X>, AutoCloseable
Deprecated.
An
Iteration
that can be closed to free resources that it is holding. CloseableIterations automatically free
their resources when exhausted. If not read until exhaustion or if you want to make sure the iteration is properly
closed, any code using the iterator should be placed in a try-with-resources block, closing the iteration
automatically, e.g.:
try (CloseableIteration<Object, Exception> iter = ...) { // read objects from the iterator } catch(Exception e) { // process the exception that can be thrown while processing. }

Deprecated.Convert the results to a Java 8 Stream. -
close
Deprecated.Closes this iteration, freeing any resources that it is holding. If the iteration has already been closed then invoking this method has no effect.- Specified by:

X extends Exception

Iteration
and instead declare the same interface methods directly. The interface will also stop requiring implementations to automatically close when exhausted, instead making this an optional feature and requiring the user to always call close. This interface may also be removed.
