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\&.
.PP
The default behavior is to use pointers if the data type is 4 times as big as the pointer to it\&.
.PP
Specialize for your data type to customize the behavior\&.

Example:
.PP
template<> struct _LoserTreeTraits<int> { static const bool _M_use_pointer = false; };
.PP
template<> struct _LoserTreeTraits<heavyweight_type> { static const bool _M_use_pointer = true; };
