Field Detail

pos

private int pos

Stores the position.

current

private AbstractIntHashMap.MapElement current

Stores the current element.

Constructor Detail

MapIterator

public MapIterator()

Initializes the iterator and places it to the first element.

Since:

1.00

Method Detail

next

public AbstractIntHashMap.MapElement next()

Returns the next element.

Specified by:

next in interface java.util.Iterator<AbstractIntHashMap.MapElement>

Returns:

the next element

Throws:

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

iterator

public java.util.Iterator<AbstractIntHashMap.MapElement> iterator()

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

Specified by:

iterator in interface java.lang.Iterable<AbstractIntHashMap.MapElement>

Returns:

an Iterator.

hasNext

public boolean hasNext()

Returns whether there is a next element.

Specified by:

hasNext in interface java.util.Iterator<AbstractIntHashMap.MapElement>

Returns:

true if there is a next element, false else

findNext

protected AbstractIntHashMap.MapElement findNext(boolean throwException)

Searches for the next element, either in AbstractIntHashMap.map or in the map element chains and returns the current element (current before call). This method modifies current 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:

1.00

remove

public void remove()

Removes the current element. (not supported)

Specified by:

remove in interface java.util.Iterator<AbstractIntHashMap.MapElement>

Throws:

java.lang.UnsupportedOperationException - always
