com.tangosol.util
Class SimpleLongArray.Iterator

java.lang.Object
com.tangosol.util.SimpleLongArray.Iterator

All Implemented Interfaces:

com.oracle.common.collections.LongArray.Iterator, java.util.Iterator

Enclosing class:

SimpleLongArray

public class SimpleLongArray.Iterator

extends java.lang.Object

implements LongArray.Iterator

An Iterator that adds a "current element" concept, similar to the Map.Entry interface.

Constructor Summary

SimpleLongArray.Iterator(int iNext, boolean fForward)
Construct an iterator that will iterate over the SimpleLongArray starting with the specified index.

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.
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.

Constructor Detail

SimpleLongArray.Iterator

public SimpleLongArray.Iterator(int iNext,
                                boolean fForward)

Construct an iterator that will iterate over the SimpleLongArray starting with the specified index.

Parameters:

iNext - the index to start iterating from

Method Detail

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 com.oracle.common.collections.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 com.oracle.common.collections.LongArray.Iterator

Specified by:

next in interface java.util.Iterator

Returns:

the next element in the iteration

Throws:

java.util.NoSuchElementException - iteration has no more elements

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 com.oracle.common.collections.LongArray.Iterator

Throws:

java.lang.IllegalStateException - if the next method has not yet been called, or the remove method has already been called after the last call to the next method.

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 com.oracle.common.collections.LongArray.Iterator

Returns:

the current value

Throws:

java.lang.IllegalStateException - if the next method has not yet been called, or the remove method has already been called after the last call to the next method.

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 com.oracle.common.collections.LongArray.Iterator

Returns:

the replaced value

Throws:

java.lang.IllegalStateException - if the next method has not yet been called, or the remove method has already been called after the last call to the next method.

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 com.oracle.common.collections.LongArray.Iterator

Specified by:

remove in interface java.util.Iterator

Throws:

java.lang.UnsupportedOperationException - if the remove operation is not supported by this Iterator

java.lang.IllegalStateException - if the next method has not yet been called, or the remove method has already been called after the last call to the next method.
