template<typename Device = Kokkos::DefaultExecutionSpace>

template<class... P>

Kokkos::Bitset< Device >::Bitset ( const Impl::ViewCtorProp< P...> &  arg_prop, unsigned  arg_size  )

inline

Ensure that allocation properties are consistent.

Update 'label' property and allocate.

template<typename Device = Kokkos::DefaultExecutionSpace>

KOKKOS_FORCEINLINE_FUNCTION bool Kokkos::Bitset< Device >::set ( unsigned  i ) const

inline

set i'th bit to 1 can only be called from the device

Definition at line 158 of file Kokkos_Bitset.hpp.

template<typename Device = Kokkos::DefaultExecutionSpace>

KOKKOS_FORCEINLINE_FUNCTION bool Kokkos::Bitset< Device >::reset ( unsigned  i ) const

inline

set i'th bit to 0 can only be called from the device

Definition at line 171 of file Kokkos_Bitset.hpp.

template<typename Device = Kokkos::DefaultExecutionSpace>

KOKKOS_FORCEINLINE_FUNCTION bool Kokkos::Bitset< Device >::test ( unsigned  i ) const

inline

return true if the i'th bit set to 1 can only be called from the device

Definition at line 184 of file Kokkos_Bitset.hpp.

template<typename Device = Kokkos::DefaultExecutionSpace>

KOKKOS_FORCEINLINE_FUNCTION unsigned Kokkos::Bitset< Device >::max_hint ( ) const

inline

used with find_any_set_near or find_any_unset_near functions returns the max number of times those functions should be call when searching for an available bit

Definition at line 201 of file Kokkos_Bitset.hpp.

template<typename Device = Kokkos::DefaultExecutionSpace>

KOKKOS_INLINE_FUNCTION Kokkos::pair<bool, unsigned> Kokkos::Bitset< Device >::find_any_set_near ( unsigned  hint, unsigned  scan_direction = BIT_SCAN_FORWARD_MOVE_HINT_FORWARD  ) const

inline

find a bit set to 1 near the hint returns a pair< bool, unsigned> where if result.first is true then result.second is the bit found and if result.first is false the result.second is a new hint

Definition at line 208 of file Kokkos_Bitset.hpp.
