Name
BitArray
Synopsis
This class stores a collection of bit values
as boolean types. The constructor takes many different forms of input to
build the initial array, including arguments that specify the initial
values and the size of the array. You can construct the BitArray
with an existing array of bools, or with a byte
or integer array. With an integer array, each int
value becomes 32 bits of
the BitArray
, with the least significant bit mapped to
the lowest index value (MyBitArray[0]
) of the 32-bit
range. A byte array uses 8 bits for each value in a similar fashion. A
“bare” array can be constructed by simply providing an integer value for
the number of bits in the BitArray
, which are all
set to false
by default. Provide an additional boolean
value as a second argument to set the default values to either true
or false
.
The main functions of the BitArray
class allow you to perform bitwise
operations with two BitArray
s of the same length. There are methods for And()
, Or()
, and Xor()
that correspond to their respective bitwise
operations.
The Not()
method inverts each bit value in the BitArray
.
