Detailed Description

template<class T, class ITER_IMP, class TAG_TYPE = std::bidirectional_iterator_tag>
class bslstl::BidirectionalIterator< T, ITER_IMP, TAG_TYPE >

Given an ITER_IMP type that implements a minimal subset of an iterator interface, this template generates a complete iterator that meets all of the requirements of a "bidirectional iterator" in the C++ standard. If T is const-qualified, then the resulting type is a constant iterator. T shall not be a function, reference type or void. ITER_IMP must provide public operations so that, for objects i and j of type ITER_IMP, the following operations are supported:

   ITER_IMP i;                            default construction
   ITER_IMP j(i);                         copy construction
   i = j                                  assignment
   ++i                                    increment to next element
   --i                                    decrement to previous element
   i == j // convertible to bool          equality comparison
   *i     // reference convertible to T&  element access (dereference)

Constructor & Destructor Documentation

BidirectionalIterator() [1/4]

template<class T , class ITER_IMP , class TAG_TYPE >

bslstl::BidirectionalIterator< T, ITER_IMP, TAG_TYPE >::BidirectionalIterator ( )

inline

Construct the default value for this iterator type. All default- constructed BidirectionalIterator objects represent non-dereferenceable iterators into the same empty range. They do not have a singular value unless an object of the type specified by the template parameter ITER_IMP has a singular value after value-initialization.

BidirectionalIterator() [2/4]

template<class T , class ITER_IMP , class TAG_TYPE >

bslstl::BidirectionalIterator< T, ITER_IMP, TAG_TYPE >::BidirectionalIterator ( const ITER_IMP &  implementation )

inline

Construct a bidirectional iterator having the specified implementation of the parameterized ITER_IMP type.

BidirectionalIterator() [3/4]

template<class T , class ITER_IMP , class TAG_TYPE = std::bidirectional_iterator_tag>

bslstl::BidirectionalIterator< T, ITER_IMP, TAG_TYPE >::BidirectionalIterator

(

const BidirectionalIterator< T, ITER_IMP, TAG_TYPE > &

original

)

BidirectionalIterator() [4/4]

template<class T , class ITER_IMP , class TAG_TYPE >

bslstl::BidirectionalIterator< T, ITER_IMP, TAG_TYPE >::BidirectionalIterator ( const BidirectionalNonConstIterator &  other )

inline

Construct a bidirectional iterator from the specified other iterator of another (compatible) BidirectionalIterator type, e.g., a mutable iterator of the same type. Note that this constructor may be the copy constructor (inhibiting the implicit declaration of a copy constructor above), or may be an additional overload.

~BidirectionalIterator()

template<class T , class ITER_IMP , class TAG_TYPE = std::bidirectional_iterator_tag>

bslstl::BidirectionalIterator< T, ITER_IMP, TAG_TYPE >::~BidirectionalIterator

(

)

Destroy this iterator. Note that this method's definition is compiler generated.

Member Function Documentation

operator++()

template<class T , class ITER_IMP , class TAG_TYPE >

BidirectionalIterator< T, ITER_IMP, TAG_TYPE > & bslstl::BidirectionalIterator< T, ITER_IMP, TAG_TYPE >::operator++ ( )

inline

Increment to the next element. Return a reference to this modifiable iterator. The behavior is undefined if, on entry, this iterator has the past-the-end value for an iterator over the underlying sequence.

operator--()

template<class T , class ITER_IMP , class TAG_TYPE >

BidirectionalIterator< T, ITER_IMP, TAG_TYPE > & bslstl::BidirectionalIterator< T, ITER_IMP, TAG_TYPE >::operator-- ( )

inline

Decrement to the previous element. Return a reference to this modifiable iterator. The behavior is undefined if, on entry, this iterator has the same value as an iterator the refers to the start of the underlying sequence.

operator=() [1/2]

template<class T , class ITER_IMP , class TAG_TYPE = std::bidirectional_iterator_tag>

BidirectionalIterator & bslstl::BidirectionalIterator< T, ITER_IMP, TAG_TYPE >::operator=

(

const BidirectionalIterator< T, ITER_IMP, TAG_TYPE > &

rhs

)

Copy the value of the specified rhs to this iterator. Return a reference to this modifiable object. Note that this method's definition is compiler generated.

operator=() [2/2]

template<class T , class ITER_IMP , class TAG_TYPE >

BidirectionalIterator< T, ITER_IMP, TAG_TYPE > & bslstl::BidirectionalIterator< T, ITER_IMP, TAG_TYPE >::operator= ( const BidirectionalNonConstIterator &  rhs )

inline

Copy the value of the specified rhs of another (compatible) BidirectionalIterator type, (e.g., a mutable iterator of the same type) to this iterator. Return a reference to this modifiable object. Note that this method may be the copy-assignment operator (inhibiting the implicit declaration of a copy-assignment operator above), or may be an additional overload.
