<div class="textblock"><h3>template<typename _Tp><br />
struct __gnu_parallel::_LoserTreeTraits< _Tp ></h3>
<p>Traits for determining whether the loser tree should use pointers or copies. </p>
<p>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.</p>
<p>The default behavior is to use pointers if the data type is 4 times as big as the pointer to it.</p>
<p>Specialize for your data type to customize the behavior.</p>
<p>Example:</p>
<p>template<> struct _LoserTreeTraits<int> { static const bool _M_use_pointer = false; };</p>
<p>template<> struct _LoserTreeTraits<heavyweight_type> { static const bool _M_use_pointer = true; };</p>
