Method Details

distanceToNext

public static <T> Map.Entry<Integer,T> distanceToNext(ListIterator<T> listIterator,
 Predicate<? super T> predicate)

Return the number of .next() invocations needed to obtain the next item. A result of 0 indicates that no such item exists.

Type Parameters:

T -

Parameters:

listIterator -

predicate -

Returns:

distanceToPrevious

public static <T> Map.Entry<Integer,T> distanceToPrevious(ListIterator<T> listIterator,
 Predicate<? super T> predicate)

repeatPrevious

public static int repeatPrevious(ListIterator<?> listIterator,
 int n)

Attempt to invoke .previous up to 'n' times and abort if .hasPrevious is false. Returns the number of actual invocations.

Parameters:

listIterator -

n -

Returns:

repeatNext

public static int repeatNext(ListIterator<?> listIterator,
 int n)

getItemNext

public static <T> T getItemNext(ListIterator<T> listIterator,
 int n)

getItemPrevious

public static <T> T getItemPrevious(ListIterator<T> listIterator,
 int n)
