  Modifier and Type	Method and Description
  void	close() Indicates that this iterator is no longer needed and that any associated resources may be released (such as a SQLite cursor).
  abstract Entity	getEntityAndIncrementCursor(Cursor cursor) Returns the entity that the cursor is currently pointing to.
  boolean	hasNext() Returns whether there are more elements to iterate, i.e.
  Entity	next() Returns the next object in the iteration, i.e.

  • CursorEntityIterator

    public CursorEntityIterator(Cursor cursor)

    Constructor that makes initializes the cursor such that the iterator points to the first Entity, if there are any.

    Parameters:

    cursor - the cursor that contains the rows that make up the entities

• Method Detail

  • getEntityAndIncrementCursor

    public abstract Entity getEntityAndIncrementCursor(Cursor cursor)
                                                throws RemoteException

    Returns the entity that the cursor is currently pointing to. This must take care to advance the cursor past this entity. This will never be called if the cursor is at the end.

    Parameters:

    cursor - the cursor that contains the entity rows

    Returns:

    the entity that the cursor is currently pointing to

    Throws:

    RemoteException - if a RemoteException is caught while attempting to build the Entity

  • hasNext

    public final boolean hasNext()

    Returns whether there are more elements to iterate, i.e. whether the iterator is positioned in front of an element.

    Specified by:

    hasNext in interface Iterator<Entity>

    Returns:

    true if there are more elements, false otherwise.

    See Also:

    Iterator.next()

  • next

    public Entity next()

    Returns the next object in the iteration, i.e. returns the element in front of the iterator and advances the iterator by one position.

    Specified by:

    next in interface Iterator<Entity>

    Returns:

    the next object.

    Throws:

    NoSuchElementException - if there are no more elements.

    See Also:

    Iterator.hasNext()

  • remove

    public void remove()

    Description copied from interface: Iterator
    Removes the last object returned by next from the collection. This method can only be called once between each call to next.

    Specified by:

    remove in interface Iterator<Entity>

  • reset

    public final void reset()

    Description copied from interface: EntityIterator
    Reset the iterator back to the beginning.

    Specified by:

    reset in interface EntityIterator

  • close

    public final void close()

    Indicates that this iterator is no longer needed and that any associated resources may be released (such as a SQLite cursor).

    Specified by:

    close in interface EntityIterator
