Detailed Description

template<concepts::KeyValueRdd R>
class cpark::GroupByKeyRdd< R >::Iterator

An Iterator that will calculate and store the group-by-key results in a shared state.

Constructor & Destructor Documentation

Iterator() [1/2]

template<concepts::KeyValueRdd R>

cpark::GroupByKeyRdd< R >::Iterator::Iterator ( std::ranges::subrange< std::ranges::iterator_t< std::ranges::range_value_t< R > > >  original_data, bool  is_end  )

inlineexplicit

Creates the iterator with

Parameters

original_data	A subrange representing the original key-value data to be grouped.
is_end	Whether this iterator is an end sentinel.

Iterator() [2/2]

template<concepts::KeyValueRdd R>

cpark::GroupByKeyRdd< R >::Iterator::Iterator ( bool  is_end )

inlineexplicit

Creates the iterator of empty data with

Parameters

is_end

Whether this iterator is an end sentinel.

Member Function Documentation

operator==()

template<concepts::KeyValueRdd R>

bool cpark::GroupByKeyRdd< R >::Iterator::operator== ( const Iterator &  other ) const

inline

Two iterators are equal iff: they are both end sentinels, or they have the same shared data and point to the same element.
