Method Detail

hasNext

public boolean hasNext()

Specified by:

hasNext in interface Iterator<INode>

next

public INode next()

Specified by:

next in interface Iterator<INode>

hasPrevious

public boolean hasPrevious()

Description copied from interface: BidiIterator

Returns true if this bidi iterator has more elements when traversing in the reverse direction. (In other words, returns true if previous would return an element rather than throwing an exception.)

Specified by:

hasPrevious in interface BidiIterator<INode>

Returns:

true if the bidi iterator has more elements when traversing in the reverse direction.

previous

public INode previous()

Description copied from interface: BidiIterator

Returns the previous element. This method may be called repeatedly to iterate backwards, or intermixed with calls to next to go back and forth. (Note that alternating calls to next and previous will return the same element repeatedly.)

Specified by:

previous in interface BidiIterator<INode>

Returns:

the previous element.
