std::ostream & | operator<< (std::ostream &stream, const Mask &m) |
Class defines a flag mask that can set or reset certain bits to predefined values. Thus it consists of a mask
part that specifies bits which are set to the second part set
.
A Mask can be applied to an FlagArray via FlagArray::set() method, masks can be combined through the "&" operator and can be used to test flags via FlagArray::is() method.

Simple constructor. Namely to get elementary mask for one bit, e.g.

Returns bitset set1
with bits given by mask
set to the values given by the bitset set2
.

inlineconstexpr |
Returns true if bits in passed flags
are 1 on positions masked (equal to 1) by the Mask.

Apply mask other
to *this mask. That is, join bit masks and overwrite bits given by other.mask_
by outher.set_
values. The action of the result Mask on the FlagArray (method set()
) is the same as application of *this followed by the application of other
