Class ArrayLongIterator

java.lang.Object
  org.joda.primitives.iterator.impl.ArrayLongIterator

All Implemented Interfaces:

Iterator<Long>, LongIterator, PrimitiveIterator<Long>

public class ArrayLongIterator
extends Object
implements LongIterator

An iterator over an array of long values.

This class implements Iterator allowing seamless integration with other APIs.

The iterator can be reset to the start if required. It is unmodifiable and remove() is unsupported.

Constructor Detail

ArrayLongIterator

public ArrayLongIterator(long[] array)

Constructs an iterator over an array of long values.

The array is assigned internally, thus the caller holds a reference to the internal state of the returned iterator. It is not recommended to modify the state of the array after construction.

Parameters:

array - the array to iterate over, must not be null

Throws:

IllegalArgumentException - if the array is null

Method Detail

copyOf

public static ArrayLongIterator copyOf(long[] array)

Creates an iterator over a copy of an array of long values.

The specified array is copied, making this class effectively immutable. Note that the class is not final thus it is not truly immutable.

Parameters:

array - the array to iterate over, must not be null

Throws:

IllegalArgumentException - if the array is null

isModifiable

public boolean isModifiable()

Description copied from interface: PrimitiveIterator

Checks whether the iterator can currently be modified.

Specified by:

isModifiable in interface PrimitiveIterator<Long>

Returns:

true if the modification methods of the iterator can be used

isResettable

public boolean isResettable()

Description copied from interface: PrimitiveIterator

Checks whether the iterator can be reset.

Specified by:

isResettable in interface PrimitiveIterator<Long>

Returns:

true if the object can be reset

hasNext

public boolean hasNext()

Specified by:

hasNext in interface Iterator<Long>

nextLong

public long nextLong()

Description copied from interface: LongIterator

Gets the next value from the iterator

Specified by:

nextLong in interface LongIterator

Returns:

the next available value

next

public Long next()

Specified by:

next in interface Iterator<Long>

remove

public void remove()

Specified by:

remove in interface Iterator<Long>

reset

public void reset()

Description copied from interface: PrimitiveIterator

Resets the iterator back to its initial state (optional operation).

Specified by:

reset in interface PrimitiveIterator<Long>
