public abstract class AbstractByteBidirectionalIterator extends AbstractByteIterator implements ByteBidirectionalIterator
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.
Modifier and Type | Method and Description |
---|---|
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. |
java.lang.Byte |
previous()
Delegates to the corresponding type-specific method.

previousByte()
Delegates to the corresponding generic method.
