(package private) LinkedHashMap.Entry	lastReturned
(package private) LinkedHashMap.Entry	nextEntry

Constructor Summary

private

LinkedHashMap.KeyIterator()

Method Summary

boolean	hasNext() Returns true if the iteration has more elements.

Field Detail

nextEntry

LinkedHashMap.Entry nextEntry

lastReturned

LinkedHashMap.Entry lastReturned

expectedModCount

int expectedModCount

The modCount value that the iterator believes that the backing List should have. If this expectation is violated, the iterator has detected concurrent modification.

Method Detail

next

public Object next()

Description copied from interface: Iterator

Returns the next element in the iteration.

Returns:

the next element in the iteration.

hasNext

public boolean hasNext()

Description copied from interface: Iterator

Returns true if the iteration has more elements. (In other words, returns true if next would return an element rather than throwing an exception.)

Specified by:

hasNext in interface Iterator

Returns:

true if the iterator has more elements.

remove

public void remove()

Description copied from interface: Iterator

Removes from the underlying collection the last element returned by the iterator (optional operation). This method can be called only once per call to next. The behavior of an iterator is unspecified if the underlying collection is modified while the iteration is in progress in any way other than by calling this method.

Specified by:

remove in interface Iterator

nextEntry

LinkedHashMap.Entry nextEntry()
