Logical assignments. Set each element of self to the logical AND, XOR, or OR,
respectively, of self and the corresponding bit in v .
Indexing operators RWBitRef operator[](size_t i);
Returns a reference to the i'th bit of self. This reference can be used as an
lvalue. The index i must be between 0 and size–1 , inclusive. Bounds
checking will occur.
RWBitRef operator()(size_t i);
Returns a reference to the i'th bit of self. This reference can be used as an
lvalue. The index i must be between 0 and size–1 , inclusive. No bounds
checking is done.
Public member functions void clearBit(size_t i);
Clears (i.e., sets to FALSE ) the bit with index i . The index i must be between
0 and size–1. No bounds checking is performed. The following are equivalent,
although clearBit(size_t) is slightly smaller and faster than using
operator()(size_t) :
a(i) = FALSE;
a.clearBit(i);
const RWByte* data() const;
Returns a const pointer to the raw data of self. Should be used with care.
void setBit(size_t i);
Sets (i.e., sets to TRUE ) the bit with index i . The index i must be between 0
and size–1. No bounds checking is performed. The following are equivalent,
although setBit(size_t) is slightly smaller and faster than using
operator()(size_t)
a(i) = TRUE;
a.setBit(i);
RWBoolean testBit(size_t i) const;
Tests the bit with index i . The index i must be between 0 and size–1. No
bounds checking is performed. The following are equivalent, although
testBit(size_t) is slightly smaller and faster than using
operator()(size_t) :
if( a(i) ) doSomething();
if( a.testBit(i) ) doSomething();
