Class BasicEMap.BasicEMapIterator<U>

java.lang.Object
  org.eclipse.emf.common.util.BasicEMap.BasicEMapIterator<U>

All Implemented Interfaces:

java.util.Iterator<U>

Direct Known Subclasses:

BasicEMap.BasicEMapKeyIterator, BasicEMap.BasicEMapValueIterator

Enclosing class:

BasicEMap<K,V>

protected class BasicEMap.BasicEMapIterator<U>
extends java.lang.Object
implements java.util.Iterator<U>

An iterator over the map entry data.

Field Summary

protected int	cursor The cursor in the entry data.
protected int	entryCursor The cursor in the list of entries.
protected int	expectedModCount The modification count expected of the map.
protected int	lastCursor The last cursor in the entry data.
protected int	lastEntryCursor The cursor in the list of entries.

Method Summary

boolean	hasNext() Returns whether there are more objects.
U	next() Returns the next object and advances the iterator.
void	remove() Removes the entry of the last object returned by next() from the map, it's an optional operation.
protected void	scan() Scans to the new entry.
protected U	yield(BasicEMap.Entry<K,V> entry) Called to yield the iterator result for the entry.

Field Detail

cursor

protected int cursor

The cursor in the entry data.

entryCursor

protected int entryCursor

The cursor in the list of entries.

lastCursor

protected int lastCursor

The last cursor in the entry data.

lastEntryCursor

protected int lastEntryCursor

The cursor in the list of entries.

expectedModCount

protected int expectedModCount

Method Detail

yield

protected U yield(BasicEMap.Entry<K,V> entry)

Called to yield the iterator result for the entry. This implementation returns the entry itself.

Parameters:

entry - the entry.

Returns:

the iterator result for the entry.

scan

protected void scan()

Scans to the new entry.

hasNext

public boolean hasNext()

Returns whether there are more objects.

Specified by:

hasNext in interface java.util.Iterator<U>

Returns:

whether there are more objects.

next

public U next()

Returns the next object and advances the iterator.

Specified by:

next in interface java.util.Iterator<U>

Returns:

the next object.

Throws:

java.util.NoSuchElementException - if the iterator is done.

remove

public void remove()

Removes the entry of the last object returned by next() from the map, it's an optional operation.

Specified by:

remove in interface java.util.Iterator<U>

Throws:

java.lang.IllegalStateException - if next has not yet been called, or remove has already been called after the last call to next.
