NAME

       __gnu_parallel::_LoserTreeTraits< _Tp > -

SYNOPSIS

   Static Public Attributes
       static const bool _M_use_pointer

Detailed Description

   template<typename _Tp>
       struct __gnu_parallel::_LoserTreeTraits< _Tp >" Traits for determining whether the loser
       tree should use pointers or copies.

       The field '_M_use_pointer' is used to determine whether to use pointers in he loser trees
       or whether to copy the values into the loser tree.

       The default behavior is to use pointers if the data type is 4 times as big as the pointer
       to it.

       Specialize for your data type to customize the behavior.

       Example:

       template<> struct _LoserTreeTraits<int> { static const bool _M_use_pointer = false; };

       template<> struct _LoserTreeTraits<heavyweight_type> { static const bool _M_use_pointer =
       true; };

       Parameters:
           _Tp type to give the loser tree traits for.
