std.bitmanip.BitArray.opBinary - multiple declarations

Function BitArray.opBinary

Support for binary bitwise operators for BitArray.

BitArray opBinary(string op) (
  const BitArray e2
) const pure nothrow
if (op == "-" || op == "&" || op == "|" || op == "^");

Example

static bool[] ba = [1,0,1,0,1];
static bool[] bb = [1,0,1,1,0];

auto a = BitArray(ba);
auto b = BitArray(bb);

BitArray c = a & b;

writeln(c[0]); // 1
writeln(c[1]); // 0
writeln(c[2]); // 1
writeln(c[3]); // 0
writeln(c[4]); // 0

Example

bool[] ba = [1,0,1,0,1];
bool[] bb = [1,0,1,1,0];

auto a = BitArray(ba);
auto b = BitArray(bb);

BitArray c = a | b;

writeln(c[0]); // 1
writeln(c[1]); // 0
writeln(c[2]); // 1
writeln(c[3]); // 1
writeln(c[4]); // 1

Example

bool[] ba = [1,0,1,0,1];
bool[] bb = [1,0,1,1,0];

auto a = BitArray(ba);
auto b = BitArray(bb);

BitArray c = a ^ b;

writeln(c[0]); // 0
writeln(c[1]); // 0
writeln(c[2]); // 0
writeln(c[3]); // 1
writeln(c[4]); // 1

Example

bool[] ba = [1,0,1,0,1];
bool[] bb = [1,0,1,1,0];

auto a = BitArray(ba);
auto b = BitArray(bb);

BitArray c = a - b;

writeln(c[0]); // 0
writeln(c[1]); // 0
writeln(c[2]); // 0
writeln(c[3]); // 0
writeln(c[4]); // 1

Function BitArray.opBinary

Support for binary operator ~ for BitArray.

BitArray opBinary(string op) (
  bool b
) const pure nothrow
if (op == "~");

BitArray opBinary(string op) (
  BitArray b
) const pure nothrow
if (op == "~");

Example

bool[] ba = [1,0];
bool[] bb = [0,1,0];

auto a = BitArray(ba);
auto b = BitArray(bb);
BitArray c;

c = (a ~ b);
writeln(c.length); // 5
writeln(c[0]); // 1
writeln(c[1]); // 0
writeln(c[2]); // 0
writeln(c[3]); // 1
writeln(c[4]); // 0

c = (a ~ true);
writeln(c.length); // 3
writeln(c[0]); // 1
writeln(c[1]); // 0
writeln(c[2]); // 1

c = (false ~ a);
writeln(c.length); // 3
writeln(c[0]); // 0
writeln(c[1]); // 1
writeln(c[2]); // 0
