Constructor and Description
UnmodifiableIterator(LongArray.Iterator<V> iterator) Construct a wrapper for the specified Iterator.

Method Summary

Modifier and Type	Method and Description
long	getIndex() Returns the index of the current value, which is the value returned by the most recent call to the next method.
LongArray.Iterator<V>	getInternalIterator() Return the internal Iterator.
V	getValue() Returns the current value, which is the same value returned by the most recent call to the next method, or the most recent value passed to setValue if setValue were called after the next method.
boolean	hasNext() Returns true if the iteration has more elements.
V	next() Returns the next element in the iteration.
void	remove() Removes from the underlying collection the last element returned by the iterator (optional operation).
V	setValue(V oValue) Stores a new value at the current value index, returning the value that was replaced.

Field Detail

m_iteratorInternal

protected LongArray.Iterator<V> m_iteratorInternal

The internal Iterator

Constructor Detail

UnmodifiableIterator

public UnmodifiableIterator(LongArray.Iterator<V> iterator)

Construct a wrapper for the specified Iterator.

Parameters:

iterator - the iterator to create a wrapper for

Method Detail

getInternalIterator

public LongArray.Iterator<V> getInternalIterator()

Return the internal Iterator.

Returns:

the internal Iterator

hasNext

public boolean hasNext()

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 LongArray.Iterator<V>

Specified by:

hasNext in interface Iterator<V>

Returns:

true if the iterator has more elements

next

public V next()

Returns the next element in the iteration.

Specified by:

next in interface LongArray.Iterator<V>

Specified by:

next in interface Iterator<V>

Returns:

the next element in the iteration

getIndex

public long getIndex()

Returns the index of the current value, which is the value returned by the most recent call to the next method.

Specified by:

getIndex in interface LongArray.Iterator<V>

Returns:

the index of the current value

getValue

public V getValue()

Returns the current value, which is the same value returned by the most recent call to the next method, or the most recent value passed to setValue if setValue were called after the next method.

Specified by:

getValue in interface LongArray.Iterator<V>

Returns:

the current value

setValue

public V setValue(V oValue)

Stores a new value at the current value index, returning the value that was replaced. The index of the current value is obtainable by calling the getIndex method.

Specified by:

setValue in interface LongArray.Iterator<V>

Parameters:

oValue - the new value to store

Returns:

the replaced value

remove

public void remove()

Removes from the underlying collection the last element returned by the iterator (optional operation). This method can be called only once per call to next. The behavior of an iterator is unspecified if the underlying collection is modified while the iteration is in progress in any way other than by calling this method.

Specified by:

remove in interface LongArray.Iterator<V>

Specified by:

remove in interface Iterator<V>
