Masks

Detailed Description

Mask classes are abstractions for the results of vector comparisons. The actual implementation differs depending on the SIMD instruction set. On SSE they contain a full 128-bit datatype while on a different architecture they might be bit-fields.

Classes
class	Mask< T, Abi >
	The main SIMD mask class. More...

Functions
template<typename T , typename Abi >
std::ostream &	operator<< (std::ostream &out, const Vc::Mask< T, Abi > &m)
	Prints the contents of a mask into a stream object. More...

Function Documentation

std::ostream& Vc::operator<< ( std::ostream &  out, const Vc::Mask< T, Abi > &  m  )

inline

Prints the contents of a mask into a stream object.

const Vc::short_m m = Vc::short_v::IndexesFromZero() < 3;
std::cout << m << std::endl;

will output (with SSE):

m[1110 0000]

Parameters

out	Any standard C++ ostream object. For example std::cout or a std::stringstream object.
m	Any Vc::Mask object.

Returns

The ostream object: to chain multiple stream operations.

Note

With the GNU standard library this function will check whether the output stream is a tty in which case it colorizes the output.
