This struct provides a namespace for static functions to be used solely in the implementation of BitStringUtil. The "Manipulators" are intended to be provided as arguments to templates in bdlb_bitstringutil, whereas the "Accessors" are to be called directly within that component.
Declared in <bdlb_bitstringimputil.h>
struct BitStringImpUtil;| Name | Description |
|---|---|
Unnamed enum | Number of bits in a uint64_t. |
| Name | Description |
|---|---|
andEqBits | Bitwise AND the specified least-significant numBits in the specified srcValue to those in the specified dstValue starting at the specified dstIndex. The behavior is undefined unless 0 <= dstIndex, 0 <= numBits, and dstIndex + numBits <= k_BITS_PER_UINT64. |
andEqWord | Assign to the specified *dstValue the value of *dstValue bitwise AND-ed with the specified srcValue. |
find1AtMaxIndexRaw | Return the index of the highest-order set bit in the specified non-zero value. The behavior is undefined unless 0 != value. Note that this method is "raw" due to the requirement that at least one bit in value must be set. |
find1AtMinIndexRaw | Return the index of the lowest-order set bit in the specified non-zero value. The behavior is undefined unless 0 != value. Note that this method is "raw" due to the requirement that at least one bit in value must be set. |
minusEqBits | Bitwise MINUS the specified least-significant numBits in the specified srcValue from those in the specified dstValue starting at the specified dstIndex. The behavior is undefined unless 0 <= dstIndex, 0 <= numBits, and dstIndex + numBits <= k_BITS_PER_UINT64. Note that the bitwise difference, a - b, is defined in C++ code as a & ~b. |
minusEqWord | Assign to the specified *dstValue the value of *dstValue bitwise AND-ed with the complement of the specified srcValue. |
orEqBits | Bitwise OR the specified least-significant numBits in the specified srcValue to those in the specified dstValue starting at the specified dstIndex. The behavior is undefined unless 0 <= dstIndex, 0 <= numBits, and dstIndex + numBits <= k_BITS_PER_UINT64. |
orEqWord | Assign to the specified *dstValue the value of *dstValue bitwise OR-ed with the specified srcValue. |
setEqBits | Replace the specified numBits in the specified dstValue starting at the specified dstIndex with the least-significant numBits of the specified srcValue. The behavior is undefined unless 0 <= dstIndex, 0 <= numBits, and dstIndex + numBits <= k_BITS_PER_UINT64. |
setEqWord | Assign to the specified *dstValue the value of the specified srcValue. |
xorEqBits | Bitwise XOR the specified least-significant numBits in the specified srcValue to those in the specified dstValue starting at the specified dstIndex. The behavior is undefined unless 0 <= dstIndex, 0 <= numBits, and dstIndex + numBits <= k_BITS_PER_UINT64. |
xorEqWord | Assign to the specified *dstValue the value of *dstValue bitwise XOR-ed with the specified srcValue. |
