__gnu_parallel::loser_tree_traits(3) __gnu_parallel::loser_tree_traits(3)
NAME
__gnu_parallel::loser_tree_traits -
Traits for determining whether the loser tree should use pointers or
copies.
SYNOPSIS
Static Public Attributes
static const bool use_pointer
Detailed Description
template<typename T> struct __gnu_parallel::loser_tree_traits< T >
Traits for determining whether the loser tree should use pointers or
copies.
The field 'use_pointer' is used to determine whether to use pointers in
the 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 loser_tree_traits<int> { static const bool
use_pointer = false; };
template<> struct loser_tree_traits<heavyweight_type> { static const
bool use_pointer = true; };
Parameters:
T type to give the loser tree traits for.
