com.tangosol.util
Class CopyOnWriteLongArray.UnmodifiableIterator

java.lang.Object
com.tangosol.util.CopyOnWriteLongArray.UnmodifiableIterator

All Implemented Interfaces:

LongArray.Iterator, java.util.Iterator

Enclosing class:

CopyOnWriteLongArray

public static class CopyOnWriteLongArray.UnmodifiableIterator

extends java.lang.Object

implements LongArray.Iterator

Unmodifiable view of a LongArray.Iterator.

Field Summary

protected LongArray.Iterator

m_iteratorInternal The internal Iterator

Constructor Summary

CopyOnWriteLongArray.UnmodifiableIterator(LongArray.Iterator iterator)
Construct a wrapper for the specified Iterator.

Method Summary

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	getInternalIterator() Return the internal Iterator.
java.lang.Object	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.
java.lang.Object	next() Returns the next element in the iteration.
void	remove() Removes from the underlying collection the last element returned by the iterator (optional operation).
java.lang.Object	setValue(java.lang.Object oValue) Stores a new value at the current value index, returning the value that was replaced.

Field Detail

m_iteratorInternal

protected LongArray.Iterator m_iteratorInternal

The internal Iterator

Constructor Detail

CopyOnWriteLongArray.UnmodifiableIterator

public CopyOnWriteLongArray.UnmodifiableIterator(LongArray.Iterator iterator)

Construct a wrapper for the specified Iterator.

Parameters:

iterator - the iterator to create a wrapper for

Method Detail

getInternalIterator

public LongArray.Iterator 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

Specified by:

hasNext in interface java.util.Iterator

Returns:

true if the iterator has more elements

next

public java.lang.Object next()

Returns the next element in the iteration.

Specified by:

next in interface LongArray.Iterator

Specified by:

next in interface java.util.Iterator

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

getValue

public java.lang.Object 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

Returns:

the current value

setValue

public java.lang.Object setValue(java.lang.Object 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

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

Specified by:

remove in interface java.util.Iterator
