java.lang.Object
  com.neeve.lang.XDoubleArrayIterator

All Implemented Interfaces:

XDoubleIterator

public class XDoubleArrayIterator
extends Object
implements XDoubleIterator

An XDoubleIterator that wraps a double array.

Constructor Summary

XDoubleArrayIterator(double[] array)
Constructs a new array iterator.

XDoubleArrayIterator(double[] array, int offset, int length)
Constructs a new array iterator.

Method Summary

double[]	array() The array backing this iterator.
boolean	hasNext() Returns true if the iteration has more elements.
int	length() Gets the length of the iterator (the number of elements it returns starting with the offset).
double	next() Returns the next element in the iteration.
int	offset() Gets the offset into the backing array at which this iterator starts.
void	remove() Remove is not supported for array iterators.
XDoubleIterator	toFirst() Resets the iterator to the beginning.

Constructor Detail

XDoubleArrayIterator

public XDoubleArrayIterator(double[] array)

Constructs a new array iterator.

Parameters:

array - The array to iterate.

XDoubleArrayIterator

public XDoubleArrayIterator(double[] 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 double[] 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: XDoubleIterator

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 XDoubleIterator

Returns:

true if the iterator has more elements.

next

public final double next()

Description copied from interface: XDoubleIterator

Returns the next element in the iteration.

Specified by:

next in interface XDoubleIterator

Returns:

the next element in the iteration.

remove

public final void remove()

Remove is not supported for array iterators.

Specified by:

remove in interface XDoubleIterator

Throws:

UnsupportedOperationException - If called.

toFirst

public final XDoubleIterator toFirst()

Description copied from interface: XDoubleIterator

Resets the iterator to the beginning.

Specified by:

toFirst in interface XDoubleIterator
