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.
