Enclosing class:

FloatBigListIterators

public abstract static class FloatBigListIterators.AbstractIndexBasedBigListIterator
extends FloatBigListIterators.AbstractIndexBasedBigIterator
implements FloatBigListIterator

A skeletal implementation for a list-iterator backed by an index based data store. High performance concrete implementations (like the main ListIterator of ArrayList) generally should avoid using this and just implement the interface directly, but should be decent for less performance critical implementations.

As the abstract methods in this class are used in inner loops, it is generally a good idea to override the class as final as to encourage the JVM to inline them (or alternatively, override the abstract methods as final).

Method Details

hasPrevious

public boolean hasPrevious()

Description copied from interface: BidirectionalIterator

Returns whether there is a previous element.

Specified by:

hasPrevious in interface BidirectionalIterator<Float>

Returns:

whether there is a previous element.

See Also:

• ListIterator.hasPrevious()

previousFloat

public float previousFloat()

Description copied from interface: FloatBidirectionalIterator

Returns the previous element as a primitive type.

Specified by:

previousFloat in interface FloatBidirectionalIterator

Returns:

the previous element in the iteration.

See Also:

• ListIterator.previous()

nextIndex

public long nextIndex()

Description copied from interface: BigListIterator

Returns the index of the element that would be returned by a subsequent call to next. (Returns list size if the list iterator is at the end of the list.)

Specified by:

nextIndex in interface BigListIterator<Float>

Returns:

the index of the element that would be returned by a subsequent call to next, or list size if list iterator is at end of list.

See Also:

• ListIterator.nextIndex()

previousIndex

public long previousIndex()

Description copied from interface: BigListIterator

Returns the index of the element that would be returned by a subsequent call to previous. (Returns -1 if the list iterator is at the beginning of the list.)

Specified by:

previousIndex in interface BigListIterator<Float>

Returns:

the index of the element that would be returned by a subsequent call to previous, or -1 if list iterator is at beginning of list.

See Also:

• ListIterator.previousIndex()

add

public void add(float k)

Description copied from interface: FloatBigListIterator

Inserts the specified element into the list (optional operation).

Specified by:

add in interface FloatBigListIterator

See Also:

• ListIterator.add(Object)

set

public void set(float k)

Description copied from interface: FloatBigListIterator

Replaces the last element returned by next() or previous() with the specified element (optional operation).

Specified by:

set in interface FloatBigListIterator

See Also:

• ListIterator.set(Object)

back

public long back(long n)

Description copied from interface: FloatBigListIterator

Moves back for the given number of elements.

The effect of this call is exactly the same as that of calling previous() for n times (possibly stopping if BidirectionalIterator.hasPrevious() becomes false).

Specified by:

back in interface FloatBigListIterator

Parameters:

n - the number of elements to skip back.

Returns:

the number of elements actually skipped.

• BidirectionalIterator.previous()
