Shift operation by inappropriate constant
Warning
New
Last modified: 03 December 2024Reports shift operations where the shift value is a constant outside the reasonable range.
Integer shift operations outside the range 0..31
and long shift operations outside the range 0..63
are reported. Shifting by negative or overly large values is almost certainly a coding error.
Example:
int shiftSize = 32;
// Warning: shift by 32 bits is equivalent to shift by 0 bits, so there's no shift at all.
int mask = (1 << shiftSize) - 1;
- By ID
Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
