Detailed Description

template<class T>
class RWMathArrayIterator< T >

Class RWMathArray is the random access iterator for the RWMathArray collection class. The RWMathArrayIterator class behaves like a pointer to type T and is used to increment through elements of an RWMathArray.

Synopsis

template <class T>
class RWMathArray<T>::iterator;

Example

#include <rw/math/mtharray.h>
 
int main() {
  RWMathArray<int> A(5, 5, 5, rwUninitialized);
  RWMathArray<int>::iterator i = A.begin();
  RWMathArray<int>::iterator stop = A.end();
 
  // Assign a unique int value to each element of A
  for (int j = 0; i != stop; ++i, ++j) {
    *i = j;
  }
}

Constructor & Destructor Documentation

RWMathArrayIterator() [1/2]

template<class T >

RWMathArrayIterator< T >::RWMathArrayIterator ( )

inline

Constructs an iterator that is in an uninitialized state. The iterator must be initialized before it is dereferenced.

RWMathArrayIterator() [2/2]

template<class T >

RWMathArrayIterator< T >::RWMathArrayIterator ( const RWMathArrayIterator< T > & x )

inline

Constructs an RWMathArrayIterator from another RWMathArrayIterator. Initialized iterators can be obtained via RWMathArray::begin() and RWMathArray::end().

Member Function Documentation

operator*()

template<class T >

value_type & RWMathArrayIterator< T >::operator* ( ) const

inline

Returns a reference to the element pointed to by self.

operator+()

template<class T >

RWMathArrayIterator< T > RWMathArrayIterator< T >::operator+ ( difference_type d ) const

inline

Returns an RWMathArrayIterator that is d elements past (or before) self.

operator++() [1/2]

template<class T >

RWMathArrayIterator< T > & RWMathArrayIterator< T >::operator++ ( )

inline

Prefix or postfix increment or decrement operator. The RWMathArrayIterator points to the next or previous element in the RWMathArray. No error condition is set if the iterator goes past the bounds of the array. Compare to RWMathArray::begin() and RWMathArray::end() to check that the iterator position is valid.

operator++() [2/2]

template<class T >

RWMathArrayIterator< T > RWMathArrayIterator< T >::operator++ ( int )

inline

Prefix or postfix increment or decrement operator. The RWMathArrayIterator points to the next or previous element in the RWMathArray. No error condition is set if the iterator goes past the bounds of the array. Compare to RWMathArray::begin() and RWMathArray::end() to check that the iterator position is valid.

operator+=()

template<class T >

RWMathArrayIterator< T > & RWMathArrayIterator< T >::operator+= ( difference_type d )

inline

Moves the RWMathArrayIterator forward or backward d elements in the RWMathArray. No error condition is set if the iterator goes past the bounds of the array. Incrementing by d and then decrementing by d returns the iterator to its original position, even if doing so takes it past the bounds of the array.

operator-() [1/2]

template<class T >

difference_type RWMathArrayIterator< T >::operator- ( const RWMathArrayIteratorBase< T > & i ) const

inline

If the return value is positive, the RWMathArrayIterator is that many elements past the iterator i. If the return value is negative, the RWMathArrayIterator is that many elements before the iterator i.

operator-() [2/2]

template<class T >

RWMathArrayIterator< T > RWMathArrayIterator< T >::operator- ( difference_type d ) const

inline

Returns an RWMathArrayIterator that is d elements past (or before) self.

operator--() [1/2]

template<class T >

RWMathArrayIterator< T > & RWMathArrayIterator< T >::operator-- ( )

inline

Prefix or postfix increment or decrement operator. The RWMathArrayIterator points to the next or previous element in the RWMathArray. No error condition is set if the iterator goes past the bounds of the array. Compare to RWMathArray::begin() and RWMathArray::end() to check that the iterator position is valid.

operator--() [2/2]

template<class T >

RWMathArrayIterator< T > RWMathArrayIterator< T >::operator-- ( int )

inline

Prefix or postfix increment or decrement operator. The RWMathArrayIterator points to the next or previous element in the RWMathArray. No error condition is set if the iterator goes past the bounds of the array. Compare to RWMathArray::begin() and RWMathArray::end() to check that the iterator position is valid.

operator-=()

template<class T >

RWMathArrayIterator< T > & RWMathArrayIterator< T >::operator-= ( difference_type d )

inline

Moves the RWMathArrayIterator forward or backward d elements in the RWMathArray. No error condition is set if the iterator goes past the bounds of the array. Incrementing by d and then decrementing by d returns the iterator to its original position, even if doing so takes it past the bounds of the array.

operator->()

template<class T >

pointer RWMathArrayIterator< T >::operator-> ( ) const

inline

For iterator a, and identifier m, a->m is equivalent to (*a).m.

operator=()

template<class T >

RWMathArrayIterator< T > & RWMathArrayIterator< T >::operator= ( const RWMathArrayIterator< T > & x )

inline

Sets the RWMathArrayIterator state to be the same state as i.

operator[]()

template<class T >

value_type & RWMathArrayIterator< T >::operator[] ( difference_type n ) const

inline

Returns a reference to the element that is n elements after self if n is positive, or n elements before self if n is negative.
