Class SimpleLongArray.Iterator

java.lang.Object
  extended by com.tangosol.util.SimpleLongArray.Iterator
All Implemented Interfaces:
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 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
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 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 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 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 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.
