Constructor and Description
TIntIterator(TIntHash hash) Creates a TIntIterator for the elements in the specified collection.

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.
int	next() Advances the iterator to the next element in the underlying collection and returns it.

Field Detail

_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.

Constructor Detail

TIntIterator

public TIntIterator(TIntHash hash)

Creates a TIntIterator for the elements in the specified collection.

Method Detail

next

public int next()

Advances the iterator to the next element in the underlying collection and returns it.

Returns:

the next int in the collection

Throws:

java.util.NoSuchElementException - if the iterator is already exhausted

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:

java.util.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.
