ALL(3G) [FIXME: manual] ALL(3G)

all - check whether all elements of a boolean vector are true

bool all(bvec x);

x

Specifies the vector to be tested for truth.

all returns true if all elements of x are true and false otherwise. It is functionally equivalent to:



    bool all(bvec x)       // bvec can be bvec2, bvec3 or bvec4


    {


        bool result = true;


        int i;


        for (i = 0; i < x.length(); ++i)


        {


            result &= x[i];


        }


        return result;


    }
