Primitive random-access iterator over a block-based deque.
Declared in <bslalg_dequeiterator.h>
template<
class VALUE_TYPE,
int BLOCK_LENGTH>
class DequeIterator;Implementation of a deque iterator, parameterized by the VALUE_TYPE, for a deque with the parameterized BLOCK_LENGTH, and suitable for use by the bslstl::RandomAccessIterator adapter. Note that BLOCK_LENGTH is the number of items of VALUE_TYPE within a block, not the size of a block in bytes.
| Name | Description |
|---|---|
DequeIterator [constructor] | Constructors |
blockBegin | Return the address of the first element in the block pointed to by this iterator. |
blockEnd | Return the address of (one-past) the last element in the block pointed to by this iterator. |
blockPtr | Return the address of the block pointer for this iterator. |
nextBlock | Set this iterator to point to the first element of the next block. |
offsetInBlock | Return the offset of the element pointed to by this iterator, from the beginning of the block containing it. |
operator* | Return a reference to the element pointed to by this iterator. |
operator+ | Return an iterator pointing the element at the specified offset after this iterator. |
operator++ | Increment this iterator to the next element in the deque. |
operator+= | Advance this iterator by the specified offset. |
operator- | Subtraction operators |
operator-- | Decrement this iterator to the previous element in the deque. |
operator-= | Move this iterator backward by the specified offset. |
previousBlock | Set this iterator to point to the first (not the last) element of the previous block. |
remainingInBlock | Return how many elements remain in this block from the current position. |
setBlock | Set this iterator to point to the first element of the block pointed to by the specified blockPtrPtr. |
valuePtr | Return the address of the parameterized VALUE_TYPE object pointed to by this iterator. |
valuePtrDecrement | Decrement the value pointer within the current block. |
valuePtrIncrement | Increment the value pointer within the current block. |

BloombergLP::bslalg::operator<=> | Perform a three-way comparison between the specified lhs and rhs iterators. The behavior is undefined unless lhs and rhs are iterators over the same deque. |
BloombergLP::bslalg::operator== | Return true if lhs and rhs point to the same element. |
