characteristics

public int characteristics()

Description copied from interface: StepperLike

Characteristics are bit flags that indicate runtime characteristics of this Stepper.

- Distinct means that no duplicates exist - Immutable means that the underlying collection is guaranteed not to change during traversal - NonNull means that no nulls will be returned during traversal - Sized means that the collection knows its exact size - SubSized means that sub-Steppers created with substep() will also know their own size. SubSized steppers must also be Sized.

The Java flags CONCURRENT and SORTED are not supported; modification of a concurrency-aware underlying collection is not guaranteed to be any safer than modification of any generic mutable collection, and if the underlying collection is ordered by virtue of sorting, Stepper will not keep track of that fact.

substep

public LongStepper substep()

Description copied from interface: StepperLike
