Field Summary

Fields

Modifier and Type	Field and Description
protected int	_expectedSize the number of elements this iterator believes are in the data structure it accesses.

protected int	_index the index used for iteration.

Method Summary

Modifier and Type	Method and Description
boolean	hasNext() Returns true if the iterator can be advanced past its current location.
protected void	moveToNextIndex() Sets the internal index so that the `next' object can be returned.
Object	next() Moves the iterator to the next Object and returns it.
protected int	nextIndex() Returns the index of the next value in the data structure or a negative value if the iterator is exhausted.
Object	objectAtIndex(int index) Returns the object at the specified index.
void	remove() Removes the last entry returned by the iterator.

Field Detail

_hash

protected final TObjectHash _hash

_expectedSize

protected int _expectedSize

the number of elements this iterator believes are in the data structure it accesses.

_index

protected int _index

the index used for iteration.

Method Detail

objectAtIndex

public Object objectAtIndex(int index)

Returns the object at the specified index. Subclasses should implement this to return the appropriate object for the given index.

Parameters:

index - the index of the value to return.

Returns:

an Object value

next

public Object next()

Moves the iterator to the next Object and returns it.

Specified by:

next in interface Iterator

Returns:

an Object value

Throws:

ConcurrentModificationException - if the structure was changed using a method that isn't on this iterator.

NoSuchElementException - if this is called on an exhausted iterator.

nextIndex

protected final int nextIndex()

Returns the index of the next value in the data structure or a negative value if the iterator is exhausted.

Returns:

an int value

Throws:

ConcurrentModificationException - if the underlying collection's size has been modified since the iterator was created.

hasNext

public boolean hasNext()

Returns true if the iterator can be advanced past its current location.

Returns:

a boolean value

remove

public void remove()

Removes the last entry returned by the iterator. Invoking this method more than once for a single entry will leave the underlying data structure in a confused state.

moveToNextIndex

protected final void moveToNextIndex()

Sets the internal index so that the `next' object can be returned.
