### Field Summary

Fields
`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.

### Constructor Summary

Constructors
Constructor and Description
`TLongIterator(TLongHash hash)` Creates a TLongIterator for the elements in the specified collection.

### Method Summary

Methods
`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.
`long` `next()` Advances the iterator to the next element in the underlying collection 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.
`void` `remove()` Removes the last entry returned by the iterator.

### 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

#### TLongIterator

    public TLongIterator(TLongHash hash)

Creates a TLongIterator for the elements in the specified collection.

### Method Detail

#### next

    public long next()

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

Returns:
  the next long in the collection
Throws:
  `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.
