Field Detail

currentPos

private int currentPos

Stores the current position relative to AbstractLongHashMap.map.

pos

private int pos

Stores the next position relative to AbstractLongHashMap.map.

next

private HashMap.Entry<K,V> next

Stores the next element in bucket chain.

current

private HashMap.Entry<K,V> current

Stores the current element in bucket chain.

Method Detail

iterator

public java.util.Iterator<I> iterator()

Returns an iterator over a set of elements of type T.

Specified by:

iterator in interface java.lang.Iterable<I>

Returns:

an Iterator.

hasNext

public boolean hasNext()

Returns whether there is a next element.

Specified by:

hasNext in interface java.util.Iterator<I>

Returns:

true if there is a next element, false else

findNext

protected HashMap.Entry<K,V> findNext(boolean throwException)

Searches for the next element in the map element chains and returns the current element (next before call). This method modifies next as a side effect.

Parameters:

throwException - whether this method should throw an exception if there is no next element

Returns:

the current element (before the call), may be null if throwException is false

Throws:

java.util.NoSuchElementException - in case that throwException is true and there is no next element

Since:

remove

public void remove()

Specified by:

remove in interface java.util.Iterator<I>
