Bitwise MINUS a bit range from srcArray out of this array.

Synopsis

Declared in <bdlc_bitarray.h>

void
minusEqual(
    std::size_t dstIndex,
    BitArray const& srcArray,
    std::size_t srcIndex,
    std::size_t numBits);

Description

Bitwise MINUS (subtract) from the specified numBits in this array, beginning at the specified dstIndex, values from the specified srcArray beginning at the specified srcIndex (retaining the results). The behavior is undefined unless dstIndex + numBits <= length() and srcIndex + numBits <= srcArray.length(). Note that the logical difference A ‐ B is defined to be A & !B.

Parameters

Name

Description

dstIndex

starting index in this array

srcArray

array providing the bits to subtract

srcIndex

starting index in srcArray

numBits

number of bits to subtract
