Member Function Documentation

template<typename _Tp , typename _Compare >

void __gnu_parallel::_LoserTree< false, _Tp, _Compare >::__delete_min_insert	(	_Tp	__key,
		bool	__sup
	)		[inline]

Delete the _M_key smallest element and insert the element __key instead.

Parameters:

__key	the _M_key to insert
__sup	true iff __key is an explicitly marked supremum

Definition at line 324 of file losertree.h.

template<typename _Tp , typename _Compare >

int __gnu_parallel::_LoserTreeBase< _Tp, _Compare >::__get_min_source

(

)

[inline, inherited]

Returns:

the index of the sequence with the smallest element.

template<typename _Tp , typename _Compare >

unsigned int __gnu_parallel::_LoserTree< false, _Tp, _Compare >::__init_winner

(

unsigned int

__root

)

[inline]

Computes the winner of the competition at position "__root".

Called recursively (starting at 0) to build the initial tree.

Parameters:

__root

__index of the "game" to start.

Definition at line 284 of file losertree.h.

template<typename _Tp , typename _Compare >

void __gnu_parallel::_LoserTreeBase< _Tp, _Compare >::__insert_start	(	const _Tp &	__key,
		int	__source,
		bool	__sup
	)		[inline, inherited]

Initializes the sequence "_M_source" with the element "__key".

Parameters:

__key	the element to insert
__source	__index of the __source __sequence
__sup	flag that determines whether the value to insert is an explicit __supremum.
