and obtain the iterator's current position in the list. AListIteratorhas no current element; itscursor positionalways lies between the element that would be returned by a call toprevious()and the element that would be returned by a call tonext(). An iterator for a list of length...
Iterate over the FindNearby results and create a new VE_SearchResult object for each result. Add the VE_SearchResult object to a JavaScript compatible string. Return the formatted JavaScript string to the client to send to VE. Listing 18 shows how to take the id, name, description, latitude...
You may create objects yourself which will allow this statement to iterate through your object's enumeration. I recommend looking at this documentation, which will tell you what interfaces to implement and what to do to make this happen. virtual/override/new These three keywords go hand-in-hand...

Returns the next element in the list and advances the cursor position. This method may be called repeatedly to iterate through the list, or intermixed with calls toprevious()to go back and forth. (Note that alternating calls tonextandpreviouswill return the same element repeatedly.) ...
