All Implemented Interfaces:

BidirectionalIterator<java.lang.Float>, FloatBidirectionalIterator, FloatIterator, FloatListIterator, ObjectBidirectionalIterator<java.lang.Float>, ObjectIterator<java.lang.Float>, java.io.Serializable, java.lang.Cloneable, java.util.Iterator<java.lang.Float>, java.util.ListIterator<java.lang.Float>

Enclosing class:

FloatIterators

public static class FloatIterators.EmptyIterator
extends java.lang.Object
implements FloatListIterator, java.io.Serializable, java.lang.Cloneable

A class returning no elements and a type-specific iterator interface.

This class may be useful to implement your own in case you subclass a type-specific iterator.

Method Detail

hasNext

public boolean hasNext()

Specified by:

hasNext in interface java.util.Iterator<java.lang.Float>

Specified by:

hasNext in interface java.util.ListIterator<java.lang.Float>

hasPrevious

public boolean hasPrevious()

Description copied from interface: BidirectionalIterator

Returns whether there is a previous element.

Specified by:

hasPrevious in interface BidirectionalIterator<java.lang.Float>

Specified by:

hasPrevious in interface java.util.ListIterator<java.lang.Float>

Returns:

whether there is a previous element.

See Also:

ListIterator.hasPrevious()

nextFloat

public float nextFloat()

Description copied from interface: FloatIterator

Returns the next element as a primitive type.

Specified by:

nextFloat in interface FloatIterator

Returns:

the next element in the iteration.

See Also:

Iterator.next()

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 int nextIndex()

Specified by:

nextIndex in interface java.util.ListIterator<java.lang.Float>

previousIndex

public int previousIndex()

Specified by:

previousIndex in interface java.util.ListIterator<java.lang.Float>

skip

public int skip(int n)

Description copied from interface: FloatBidirectionalIterator

Skips the given number of elements.

The effect of this call is exactly the same as that of calling FloatIterator.next() for n times (possibly stopping if Iterator.hasNext() becomes false).

Specified by:

skip in interface FloatBidirectionalIterator

Specified by:

skip in interface FloatIterator

Specified by:

skip in interface ObjectBidirectionalIterator<java.lang.Float>

Specified by:

skip in interface ObjectIterator<java.lang.Float>

Parameters:

n - the number of elements to skip.

Returns:

the number of elements actually skipped.

See Also:

Iterator.next()

back

public int back(int n)

Description copied from interface: FloatBidirectionalIterator

Moves back for the given number of elements.

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

Specified by:

back in interface FloatBidirectionalIterator

Specified by:

back in interface ObjectBidirectionalIterator<java.lang.Float>

Parameters:

n - the number of elements to skip back.

Returns:

the number of elements actually skipped.

See Also:

FloatBidirectionalIterator.previous()

clone

public java.lang.Object clone()

Overrides:

clone in class java.lang.Object
