Constructor Detail

XLongArrayIterator

public XLongArrayIterator(long[] array)

Constructs a new array iterator.

Parameters:

array - The array to iterate.

XLongArrayIterator

public XLongArrayIterator(long[] array,
                          int offset,
                          int length)

Constructs a new array iterator.

Parameters:

array - The backing array.

offset - The offset into the array.

length - The length the number of elements including the offset to iterate.

Method Detail

array

public final long[] array()

The array backing this iterator.

Returns:

The array backing the iterator.

offset

public final int offset()

Gets the offset into the backing array at which this iterator starts.

Returns:

The backing array offset.

length

public final int length()

Gets the length of the iterator (the number of elements it returns starting with the offset).

Returns:

The length of elements returned from the iterator's offset.

hasNext

public final boolean hasNext()

Description copied from interface: XLongIterator

Returns true if the iteration has more elements. (In other words, returns true if next would return an element rather than throwing an exception.)

Specified by:

hasNext in interface XLongIterator

Returns:

true if the iterator has more elements.

next

public final long next()

Description copied from interface: XLongIterator

Returns the next element in the iteration.

Specified by:

next in interface XLongIterator

Returns:

the next element in the iteration.

remove

public final void remove()

Remove is not supported for array iterators.

Specified by:

remove in interface XLongIterator

Throws:

UnsupportedOperationException - If called.

toFirst

public final XLongIterator toFirst()

Description copied from interface: XLongIterator

Resets the iterator to the beginning.

Specified by:

toFirst in interface XLongIterator
