public abstract class AbstractFloatBidirectionalIterator
extends AbstractFloatIterator
implements FloatBidirectionalIterator

An abstract class facilitating the creation of type-specific bidirectional iterators.

To create a type-specific bidirectional iterator, besides what is needed for an iterator you need both a method returning the previous element as primitive type and a method returning the previous element as an object. However, if you inherit from this class you need just one (anyone).

This class implements also a trivial version of back(int) that uses type-specific methods.


Method Summary
 int back(int n)
          This method just iterates the type-specific version of previous() for at most n times, stopping if BidirectionalIterator.hasPrevious() becomes false.
 Float previous()
          Delegates to the corresponding type-specific method.
 float previousFloat()
          Delegates to the corresponding generic method.

Method Detail

previousFloat

public float previousFloat()
Delegates to the corresponding generic method.

Specified by:
previousFloat in interface FloatBidirectionalIterator
Returns:
the previous element in the iteration.
See Also:
ListIterator.previous()

previous

public Float previous()
Delegates to the corresponding type-specific method.

Specified by:
previous in interface BidirectionalIterator<Float>
Returns:
the previous element from the collection.
See Also:
ListIterator.previous()

back

public int back(int n)
This method just iterates the type-specific version of previous() for at most n times, stopping if BidirectionalIterator.hasPrevious() becomes false.

Specified by:
back in interface FloatBidirectionalIterator
Specified by:
back in interface ObjectBidirectionalIterator<Float>
Parameters:
n - the number of elements to skip back.
Returns:
the number of elements actually skipped.
