Interface TupleList

All Superinterfaces:

AutoCloseable, Collection<TupleTableSlot>, Iterable<TupleTableSlot>, List<TupleTableSlot>, SequencedCollection<TupleTableSlot>

All Known Implementing Classes:

TupleList.Empty, TupleList.SPI

public interface TupleList
extends List<TupleTableSlot>, AutoCloseable

Superinterface of one or more classes that can present a sequence of tuples, working from the forms in which PostgreSQL can present them.

Method Details

close

default void close()

Specified by:

close in interface AutoCloseable

spliterator

default Spliterator<TupleTableSlot> spliterator()

Returns a Spliterator that never splits.

Because a TupleList is typically built on a single TupleTableSlot holding each tuple in turn, there can be no thought of parallel stream execution.

Also, because a TupleList iterator may return the same TupleTableSlot repeatedly, stateful Stream operations such as distinct or sorted will make no sense applied to those objects.
