(1) The iterator category is at least a forward iterator.

(2) Iterator and reference validity are preserved.

(3) These iterator types are defined in the iterator header.

(4) An iterator pointing to the inserted element.

(5) Iterators: SPL offers some advanced iterator algorithms.

(6) Any iterator category except output iterator.

(7) A bidirectional iterator is an iterator that can read through a sequence of values.

(8) The input iterator moves on and is never stuck at the beginning.

(9) Indeed, dereferencing an iterator from an intrusive list is performed in the same two steps as described above.

(10) Imagine an iterator object as a kind of wrapper around our arrays.

(11) Returns an iterator over the elements in this list in proper sequence.

(12) A type playing the role of iterator - type in the BidirectionalIterator concept.

(13) When we assign through an insert iterator, the iterator inserts a new element.

(14) List the five iterator categories and the operations that each supports.

(15) Defines an iterator that accesses elements in a container in the reverse direction.

(16) Defines an iterator that can access elements in a container in the forward direction by using the increment operator and in the backward direction by using the decrement operator.

(17) Actually, most iterator contexts want an object that will generate an iterator when the new iter() built-in function is applied to it.

(18) Returns a list iterator of the elements in proper sequence.

(19) A type playing the role of iterator - type in the OutputIterator concept.

(20) This iterator adaptor caches the result of dereferencing the underlying iterator.

(21) Increment the iterator variable iter for each "article" element, as in Listing 20.

(22) Fundamentally, the for loop involves what is known as an iterator, which is used to move through the collection item by item.

(23) Use the function odbc_result(), which takes in a result set and a column name (as a string) and returns the cell value within the row that the row iterator points to.

(24) One way to avoid these perils is for your combiner to release any locks before dereferencing a slot call iterator.

(25) Since it is implemented as an anonymous function within another function, one could do some preliminary checks and calculations before creating the iterator.

(26) And, in most data-processing routines, sequential access to a rope's characters is what's required, in which case a rope iterator can provide amortized O(1) access speed.

(27) The familiar Python idiom for elem in lst: now actually asks lst to produce an iterator.

(28) The scanner can also be made to rebind to a different iterator type anytime.

(29) For example, findwhich implements a one - pass , read - only traversal over a containerminimally requires an input iterator.

(30) The Composite pattern can be used to implement the composite service that encompasses other subservices, whereas the Iterator pattern can be used to implement the traversal of subservices.

(31) Interface for an iterator that can access elements in a container in the forward direction by using the increment operator and in the backward direction by using the decrement operator.

(32) There are five iterator categories: input, output, forward, bidirectional, and random access.

(33) If an insert took place, then the iterator points to the newly inserted element. Otherwise,(http:///iterator.html) it points to the element with equivalent value.

(34) All of these make a copy of the iterator passed to them.

(35) You can use several design patterns, such as Composite, Iterator, and Chain of Responsibility, to implement composition variation between services.

(36) You can easily modify the Rope iterator to accommodate skipping forward by more than one character at a time.

(37) Interface for an iterator that can access elements in a container only in the forward direction by using the increment operator.

(38) Unlike an iterator, the cursor need not be advanced first (using next()) in order to get into a valid state.

(39) What is an Iterator?

(40) But moving backward is more complicated, because internally the iterator performs a depth-first, preorder traversal of the Rope, visiting each of its leaf nodes.
