All Known Subinterfaces:

ByteBigListIterator

public interface ByteBidirectionalIterator
extends ByteIterator, ObjectBidirectionalIterator<Byte>

A type-specific bidirectional iterator; provides an additional method to avoid (un)boxing, and the possibility to skip elements backwards.

Method Details

previousByte

byte previousByte()

Returns the previous element as a primitive type.

Returns:

the previous element in the iteration.

See Also:

• ListIterator.previous()

previous

@Deprecated
default Byte previous()

Deprecated.

Please use the corresponding type-specific method instead.

Returns the previous element from the collection.

Specified by:

previous in interface BidirectionalIterator<Byte>

Returns:

the previous element from the collection.

See Also:

• ListIterator.previous()

back

default int back(int n)

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 ObjectBidirectionalIterator<Byte>

Parameters:

n - the number of elements to skip back.

Returns:

the number of elements actually skipped.

See Also:

• previous()

skip

default int skip(int n)

Skips the given number of elements.

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

Specified by:

skip in interface ByteIterator

Specified by:

skip in interface ObjectBidirectionalIterator<Byte>

Specified by:

skip in interface ObjectIterator<Byte>

Parameters:

n - the number of elements to skip.

Returns:

the number of elements actually skipped.
