Detailed Description

template<typename DataIterator, typename WeightIterator>
class theplu::yat::utility::DataWeightProxy< DataIterator, WeightIterator >

Proxy class for DataWeight.

Class is used in WeightedIterator

Type Requirements (for both DataIterator and WeightIterator):

• underlying iterators are Readable Iterator
• value_type must be convertible to const double.
• reference must be convertible to const double&.
• If the DataWeightProxy is going to be used in a non-const way iterators must be mutable and reference must be exactly double&. See data(void) and weight(void).

Constructor & Destructor Documentation

DataWeightProxy()

template<typename DataIterator, typename WeightIterator>

theplu::yat::utility::DataWeightProxy< DataIterator, WeightIterator >::DataWeightProxy ( DataIterator  data, WeightIterator  weight  )

inline

Constructor.

Parameters

data	iterator pointing to data to hold
weight	iterator pointing to weight to hold

Member Function Documentation

data() [1/2]

template<typename DataIterator, typename WeightIterator>

boost::iterator_reference<DataIterator>::type theplu::yat::utility::DataWeightProxy< DataIterator, WeightIterator >::data ( void  )

inline

Returns

reference to data

This function requires that reference type of data_iterator is convertible to double. This function is typically used as left-hand side in an assignment and thus expected to being able to change the underlying data such as a double& can change the underlying double. But it is not required that return type is a double& as a Proxy class can do the job too.

data() [2/2]

template<typename DataIterator, typename WeightIterator>

const double& theplu::yat::utility::DataWeightProxy< DataIterator, WeightIterator >::data ( void  ) const

inline

Returns

const reference to data

operator=()

template<typename DataIterator, typename WeightIterator>

DataWeightProxy& theplu::yat::utility::DataWeightProxy< DataIterator, WeightIterator >::operator= ( const DataWeightProxy< DataIterator, WeightIterator > &  rhs )

inline

assignment operator

This function uses non-const function data(void) and weight(void) and consequently requires that reference type of both data_iterator and weight_iterator are convertible to double.

weight() [1/2]

template<typename DataIterator, typename WeightIterator>

boost::iterator_reference<WeightIterator>::type theplu::yat::utility::DataWeightProxy< DataIterator, WeightIterator >::weight ( void  )

inline

Returns

reference to weight

This function requires that reference type of weight_iterator is convertible to double. This function is typically used as left-hand side in an assignment and thus expected to being able to change the underlying data such as a double& can change the underlying double. But it is not required that return type is a double& as a Proxy class can do the job too.

weight() [2/2]

template<typename DataIterator, typename WeightIterator>

const double& theplu::yat::utility::DataWeightProxy< DataIterator, WeightIterator >::weight ( void  ) const

inline

Returns

const reference to weight
