__gnu_parallel::_LoserTreeBase< _Tp, _Compare >(3)    Library Functions Manual

NAME
       __gnu_parallel::_LoserTreeBase< _Tp, _Compare > - Guarded
       loser/tournament tree.


SYNOPSIS
       #include <losertree.h>

       Inherited by __gnu_parallel::_LoserTree< __stable, _Tp, _Compare >, and
       __gnu_parallel::_LoserTree< false, _Tp, _Compare >.

   Classes
       struct _Loser
           Internal representation of a _LoserTree element.

   Public Member Functions
       _LoserTreeBase (unsigned int __k, _Compare __comp)
           The constructor.
       ~_LoserTreeBase ()
           The destructor.
       int __get_min_source ()
       void __insert_start (const _Tp &__key, int __source, bool __sup)
           Initializes the sequence '_M_source' with the element '__key'.

   Protected Attributes
       _Compare _M_comp
           _Compare to use.
       bool _M_first_insert
           State flag that determines whether the _LoserTree is empty.
       unsigned int _M_ik
       unsigned int _M_k

Detailed Description
   template<typename _Tp, typename _Compare>
       class __gnu_parallel::_LoserTreeBase< _Tp, _Compare >"Guarded
       loser/tournament tree.

       The smallest element is at the top.

       Guarding is done explicitly through one flag _M_sup per element, inf is
       not needed due to a better initialization routine. This is a well-
       performing variant.

       Parameters
           _Tp the element type
           _Compare the comparator to use, defaults to std::less<_Tp>

Constructor & Destructor Documentation
   template<typename _Tp , typename _Compare > __gnu_parallel::_LoserTreeBase<
       _Tp, _Compare >::_LoserTreeBase (unsigned int __k, _Compare __comp)

       The constructor.

       Parameters
           __k The number of sequences to merge.
           __comp The comparator to use.

Member Function Documentation
   template<typename _Tp , typename _Compare > int
       __gnu_parallel::_LoserTreeBase< _Tp, _Compare >::__get_min_source ()
       [inline]
       Returns
           the index of the sequence with the smallest element.

   template<typename _Tp , typename _Compare > void
       __gnu_parallel::_LoserTreeBase< _Tp, _Compare >::__insert_start (const
       _Tp & __key, int __source, bool __sup) [inline]
       Initializes the sequence '_M_source' with the element '__key'.

       Parameters
           __key the element to insert
           __source __index of the __source __sequence
           __sup flag that determines whether the value to insert is an
           explicit __supremum.
