Public Member Functions | |
ushort_m () | |
default constructor | |
ushort_m (Vc::Zero) | |
Constructs a mask with the entries initialized to zero. | |
ushort_m (Vc::One) | |
Constructs a mask with the entries initialized to one. | |
ushort_m (bool b) | |
Constructs a mask with the entries initialized to. | |
ushort_m (const ushort_m &) | |
Standard copy constructor. | |
template<typename OtherMask > | |
ushort_m (const OtherMask &) | |
Constructs a mask object from a mask of different size/type. | |
bool | operator== (const ushort_m &) const |
Returns whether the two masks are equal in all entries. | |
bool | operator!= (const ushort_m &) const |
Returns whether the two masks differ in at least one entry. | |
ushort_m | operator&& (const ushort_m &) const |
Return the per-entry resulting mask of a logical (in this case same as bitwise) AND operation. | |
ushort_m | operator& (const ushort_m &) const |
Return the per-entry resulting mask of a logical (in this case same as bitwise) AND operation. | |
ushort_m | operator|| (const ushort_m &) const |
Return the per-entry resulting mask of a logical (in this case same as bitwise) OR operation. | |
ushort_m | operator| (const ushort_m &) const |
Return the per-entry resulting mask of a logical (in this case same as bitwise) OR operation. | |
ushort_m | operator^ (const ushort_m &) const |
Return the per-entry resulting mask of a logical (in this case same as bitwise) XOR operation. | |
ushort_m | operator! () const |
Return the per-entry resulting mask of a logical (in this case same as bitwise) NOT operation. | |
ushort_m | operator&= (const ushort_m &) |
Modify the mask per-entry using a logical (in this case same as bitwise) AND operation. | |
ushort_m | operator|= (const ushort_m &) |
Modify the mask per-entry using a logical (in this case same as bitwise) OR operation. | |
bool | isFull () const |
Return whether all entries of the mask are one. | |
bool | isEmpty () const |
Return whether all entries of the mask are zero. | |
bool | isMix () const |
Return whether the mask is neither full nor empty. | |
operator bool () const | |
Cast to bool operator. | |
bool | operator[] (int i) const |
Read-only access to mask entries. | |
int | count () const |
Return how many entries of the mask are set to one. | |
int | firstOne () const |
Returns the index of the first one in the mask. | |
int | toInt () const |
Convert mask to an integer. |
ushort_m | ( | ) |
default constructor
Leaves the mask uninitialized.
|
explicit |
Constructs a mask with the entries initialized to.
b
is true
b
is false
b | Determines the initial state of the mask. |
operator bool | ( | ) | const |
Cast to bool operator.
Returns the same as isFull().
bool operator[] | ( | int | i | ) | const |
Read-only access to mask entries.
i | Determines the boolean to be accessed. |
i
th entry of the mask as a bool. int toInt | ( | ) | const |
Convert mask to an integer.
E.g. a mask like [true, false, false, true] would result in a 9 (in binary: 1001).
