An
CloseableIteration
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. }
