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.

Specified by:

characteristics in interface StepperLike<java.lang.Object,NextStepper<java.lang.Object>>

Returns:

(undocumented)

hasStep

public boolean hasStep()

Description copied from interface: StepperLike

`true` if there are more elements to step through, `false` if not.

Specified by:

hasStep in interface StepperLike<java.lang.Object,NextStepper<java.lang.Object>>

knownSize

public long knownSize()

Description copied from interface: StepperLike

Returns the size of the collection, if known exactly, or `-1` if not.

Specified by:

knownSize in interface StepperLike<java.lang.Object,NextStepper<java.lang.Object>>

nextStep

public int nextStep()

Description copied from interface: StepperLike

The next element traversed by this Stepper. nextStep() throws an exception if no elements exist, so check hasStep immediately prior to calling. Note that tryStep also consumes an element, so the result of hasStep will be invalid after tryStep is called.

Specified by:

nextStep in interface StepperLike<java.lang.Object,NextStepper<java.lang.Object>>

Returns:

(undocumented)

substep

public NextStepper<java.lang.Object> 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.

Specified by:

substep in interface StepperLike<java.lang.Object,NextStepper<java.lang.Object>>

Returns:

(undocumented)
