Constructor & Destructor Documentation

mask() [1/2]

template<unsigned Elems>

constexpr aie::detail::mask< Elems >::mask ( bool  initial_set = false )

inlineexplicitconstexpr

Creates a mask

Parameters

initial_set

If true, the mask is initialized with 1s, otherise it is initialized with 0s.

mask() [2/2]

template<unsigned Elems>

template<typename... T>

constexpr aie::detail::mask< Elems >::mask ( unsigned  w, T &&...  words  )

inlineexplicitconstexpr

Construct from unsigned (32b) words. Each bit in the input words is used to initialize one of the elements in the mask.

Parameters

w	First word used to initialize the mask.
words	Rest of words used to initialize the mask.

Member Function Documentation

clear()

template<unsigned Elems>

constexpr void aie::detail::mask< Elems >::clear ( unsigned  i )

inlineconstexpr

Sets the value of the element in the given index to 0.

Parameters

i	Element index.

clz()

template<unsigned Elems>

constexpr unsigned aie::detail::mask< Elems >::clz ( ) const

inlineconstexpr

Returns the count of consecutive elements, starting at the high part of the mask, whose value is 0.

count()

template<unsigned Elems>

constexpr unsigned aie::detail::mask< Elems >::count ( ) const

inlineconstexpr

Returns the count of elements whose value is 1.

empty()

template<unsigned Elems>

constexpr bool aie::detail::mask< Elems >::empty ( ) const

inlineconstexpr

Returns a bool that says whether the value of all the elements in the mask is 0.

operator&()

template<unsigned Elems>

constexpr mask aie::detail::mask< Elems >::operator& ( const mask< Elems > &  a ) const

inlineconstexpr

Returns the result of merging the current and the given masks using the AND operation.

Parameters

a	Mask to merge with.

operator&=()

template<unsigned Elems>

constexpr mask& aie::detail::mask< Elems >::operator&= ( const mask< Elems > &  a )

inlineconstexpr

Updates the mask with the result of merging the current with the given masks using the AND operation. Returns a reference to the updated mask.

Parameters

a	Mask to merge with.

operator==()

template<unsigned Elems>

constexpr bool aie::detail::mask< Elems >::operator== ( const mask< Elems > &  a ) const

inlineconstexpr

Compares whether two masks are equal.

Parameters

a	Mask to compare against.

operator|()

template<unsigned Elems>

constexpr mask aie::detail::mask< Elems >::operator| ( const mask< Elems > &  a ) const

inlineconstexpr

Returns the result of merging the current and the given masks using the OR operation.

Parameters

a	Mask to merge with.

operator|=()

template<unsigned Elems>

constexpr mask& aie::detail::mask< Elems >::operator|= ( const mask< Elems > &  a )

inlineconstexpr

Updates the mask with the result of merging the current and the given masks using the OR operation. Returns a reference to the updated mask.

Parameters

a	Mask to merge with.

operator~()

template<unsigned Elems>

constexpr mask aie::detail::mask< Elems >::operator~ ( ) const

inlineconstexpr

Returns a mask that contains the negation of the values of all the elements in the mask (0->1, 1->0).

set()

template<unsigned Elems>

constexpr void aie::detail::mask< Elems >::set ( unsigned  i )

inlineconstexpr

Sets the value of the element in the given index to 1.

Parameters

i	Element index.

size()

template<unsigned Elems>

static constexpr unsigned aie::detail::mask< Elems >::size ( )

inlinestaticconstexpr

Returns the number of elements in the mask

test()

template<unsigned Elems>

constexpr bool aie::detail::mask< Elems >::test ( unsigned  i ) const

inlineconstexpr

Returns the value of the element in the given index.

Parameters

i	Element index.
