StatelessOp¶

StatelessOp is an abstract static class within Java's Stream API, serving as the base implementation for intermediate operations that do not maintain state.^[600-developer__java__java8__java8-Spliterator.md]

Definition¶

The class is formally defined as abstract static class StatelessOp<E_IN, E_OUT> extends ReferencePipeline<E_IN, E_OUT>.^[600-developer__java__java8__java8-Spliterator.md] It inherits from ReferencePipeline, which acts as an abstract base class for pipeline stages or source stages.^[600-developer__java__java8__java8-Spliterator.md]

Functionality¶

This class is specifically designed to act as the base for a stateless intermediate stage of a Stream.^[600-developer__java__java8__java8-Spliterator.md] In the context of Stream processing, "stateless" implies that the operation does not need to retain information about previously seen elements to process subsequent elements (e.g., filtering or mapping).
