Method Detail

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 DoubleStepper substep()

Description copied from interface: StepperLike

Attempt to split this Stepper in half, with the new (returned) copy taking the first half of the collection, and this one advancing to cover the second half. If subdivision is not possible or not advisable, substep() will return null.
