Method Detail

• add

  void add(boolean element)

  Inserts the specified element into my underlying collection (optional operation). The element is inserted immediately before the next element that would have been returned by next(), if any, and immediately after the next element that would have been returned by previous(), if any.

  The new element is inserted immediately before the implied cursor. A subsequent call to previous() will return the added element, a subsequent call to next() will be unaffected. This call increases by one the value that would be returned by a call to nextIndex() or previousIndex().

  Parameters:

  element - the value to be inserted

  Throws:

  UnsupportedOperationException - when this operation is not supported

  IllegalArgumentException - if some aspect of the specified element prevents it from being added

• hasNext

  boolean hasNext()

  Returns true iff I have more elements when traversed in the forward direction. (In other words, returns true iff a call to next() will return an element rather than throwing an exception.

  Specified by:

  hasNext in interface BooleanIterator

  Returns:

  true iff I have more elements when traversed in the forward direction

• hasPrevious

  boolean hasPrevious()

  Returns true iff I have more elements when traversed in the reverse direction. (In other words, returns true iff a call to previous() will return an element rather than throwing an exception.

  Returns:

  true iff I have more elements when traversed in the reverse direction

• next

  boolean next()

  Returns the next element in me when traversed in the forward direction.

  Specified by:

  next in interface BooleanIterator

  Returns:

  the next element in me

  Throws:

  NoSuchElementException - if there is no next element

• nextIndex

  int nextIndex()

  Returns the index of the element that would be returned by a subsequent call to next(), or the number of elements in my iteration if I have no next element.

  Returns:

  the index of the next element in me

• previous

  boolean previous()

  Returns the next element in me when traversed in the reverse direction.

  Returns:

  the previous element in me

  Throws:

  NoSuchElementException - if there is no previous element

• previousIndex

  int previousIndex()

  Returns the index of the element that would be returned by a subsequent call to previous(), or -1 if I have no previous element.

  Returns:

  the index of the previous element in me

• remove

  void remove()

  Removes from my underlying collection the last element returned by next() or previous() (optional operation).

  Specified by:

  remove in interface BooleanIterator

  Throws:

  UnsupportedOperationException - if this operation is not supported

  IllegalStateException - if neither next() nor previous() has yet been called, or remove() or add(boolean) has already been called since the last call to next() or previous().

• set

  void set(boolean element)

  Replaces in my underlying collection the last element returned by next() or previous() with the specified value (optional operation).

  Parameters:

  element - the value to replace the last returned element with

  Throws:

  UnsupportedOperationException - if this operation is not supported

  IllegalStateException - if neither next() nor previous() has yet been called, or remove() or add(boolean) has already been called since the last call to next() or previous().

  IllegalArgumentException - if some aspect of the specified element prevents it from being added
