Classes
struct	stapl::logical_and< T >
	Function which returns the logical and of its arguments. More...

struct	stapl::logical_not< T >
	Function which returns the logical not of its argument. More...

struct	stapl::detail::unary_negate_helper< Predicate, bool >
	Base class for unary_negate the reflects the type `argument_type` if defined in the template. More...

struct	stapl::detail::binary_negate_helper< Predicate, bool >
	Base class for binary_negate the reflects the type `first_argument_type` and `second_argument_type` if they are defined in the template. It's assumed that the two argument type parameters either both exist or both do not, so we only check for first_argument_type. More...

Detailed Description

Function objects implement logic operations. Defined in stapl/algorithms/functional.hpp.

stapl::STAPL_DEFINE_IDENTITY_VALUE	(	logical_and< long unsigned int >	,
		long unsigned	int,
		1
	)

Function which returns the logical or of its arguments.

Template Parameters

T	Type of the arguments.

template<typename Predicate >

unary_negate<Predicate> stapl::not1 ( Predicate const & pred )

Construct a unary_negate functor with the given predicate.

Parameters

pred	The predicate used to construct the functor.

template<typename Predicate >

binary_negate<Predicate> stapl::not2 ( Predicate const & pred )

Construct a binary_negate functor with the given predicate.

Parameters

pred	The predicate used to construct the functor.
