public class ProgressStepper

implements Modifiers.Center<HTMLOListElement, ProgressStepper>, Modifiers.Compact<HTMLOListElement, ProgressStepper>, HasItems<HTMLOListElement, ProgressStepper, ProgressStep>, Modifiers.Vertical<HTMLOListElement, ProgressStepper>

A progress stepper displays a timeline of tasks in a workflow and tracks a user's progress through the workflow.

The navigation semantics use a sentinel index interval of [-1, size]:

• -1 → underflow / before the first element (no current step)
• 0..n-1 → valid current step indices
• size() → overflow / after the last element (no current step)

Method Details

progressStepper

public static ProgressStepper progressStepper()

add

public ProgressStepper add(ProgressStep item)

Specified by:

add in interface HasItems<HTMLOListElement, ProgressStepper, ProgressStep>

that

public ProgressStepper that()

Specified by:

that in interface TypedBuilder<HTMLOListElement, ProgressStepper>

first

public ProgressStepper first()

Selects the first step (index 0) if available. Does nothing if there are no steps or the first step is already current.

Returns:

this instance

first

public ProgressStepper first(Consumer<ProgressStep> actionForTheFirstStep,
 Consumer<ProgressStep> actionForThePreviousCurrentStep)

Selects the first step (index 0) if available. Previous current (if any) is cleared, then the first step is marked current. No change if empty or already at index 0.

Parameters:

actionForTheFirstStep - invoked with the first step after it becomes current

actionForThePreviousCurrentStep - invoked with the previous current step after it is cleared

Returns:

this instance

previous

public ProgressStepper previous()

Moves one step backward.

Transitions:

• size → size-1 (from overflow to last)
• i > 0 → i-1 (normal backward)
• 0 → -1 (underflow; no current)
• -1 → no change

Returns:

this instance

previous

public ProgressStepper previous(BiConsumer<Optional<ProgressStep>, Integer> actionForTheNewCurrentStepWithIndex,
 Consumer<ProgressStep> actionForThePreviousCurrentStep)

Moves one step backward with callbacks. See previous() for state transitions.

Parameters:

actionForTheNewCurrentStepWithIndex - receives Optional(new step) and its index, or Optional.empty() on underflow

actionForThePreviousCurrentStep - receives the step that was current (if it existed) after clearing

Returns:

this instance

next

public ProgressStepper next()

Moves one step forward.

Transitions:

• -1 → 0 (from underflow to first)
• i < size - 1 → i + 1 (normal forward)
• size - 1 → size (overflow; no current)
• size → no change

Returns:

this instance

next

public ProgressStepper next(BiConsumer<Optional<ProgressStep>, Integer> actionForTheNewCurrentWithIndex,
 Consumer<ProgressStep> actionForThePreviousCurrent)

Moves one step forward with callbacks. See next() for state transitions.

Parameters:

actionForTheNewCurrentWithIndex - receives Optional(new step) and its index, or Optional.empty() on overflow

actionForThePreviousCurrent - receives the step that was current (if it existed) after clearing

Returns:

this instance

last

public ProgressStepper last()

Selects the last step (index size-1) if present. Does nothing if empty or already at last.

Returns:

this instance

last

public ProgressStepper last(Consumer<ProgressStep> actionForTheLastStep,
 Consumer<ProgressStep> actionForThePreviousCurrentStep)

Selects the last step (index size-1) if present. Previous current (if valid) is cleared, then the last step is marked current.

Parameters:

actionForTheLastStep - invoked with the last step after it becomes current

actionForThePreviousCurrentStep - invoked with the previous current step after it is cleared

Returns:

this instance

ariaLabel

public ProgressStepper ariaLabel(String label)

onAdd

public ProgressStepper onAdd(BiConsumer<ProgressStepper, ProgressStep> onAdd)

Specified by:

onAdd in interface HasItems<HTMLOListElement, ProgressStepper, ProgressStep>

onRemove

public ProgressStepper onRemove(BiConsumer<ProgressStepper, ProgressStep> onRemove)

Specified by:

onRemove in interface HasItems<HTMLOListElement, ProgressStepper, ProgressStep>

iterator

public Iterator<ProgressStep> iterator()

Specified by:

iterator in interface Iterable<ProgressStep>

size

Specified by:

size in interface HasItems<HTMLOListElement, ProgressStepper, ProgressStep>

item

public ProgressStep item(String identifier)

Specified by:

item in interface HasItems<HTMLOListElement, ProgressStepper, ProgressStep>

currentIndex

public int currentIndex()

Returns the index of the current progress step. The interval is [-1, size], where -1 implies no current step (before first) and size implies no current step (after last).

public ProgressStepper setupSteps(BiConsumer<ProgressStep, Integer> stepConsumerWithIndex)

Applies the provided consumer to each step with its index in insertion order.

Parameters:

stepConsumerWithIndex - consumer receiving (step, index)
