Detailed Description
The BitExtractOperator extracts a bit from some Source value (default input value).
A BitExtractOperator sets output value from Source bit given by BitNo.
Pseudocode for this operator:
Out = (bool)( Source & (1<<BitNo) );
Arguments
| Name | Description |
|---|---|
| BitNo | Zero-based index of the bit to extract from source. |
| Source (default input) | Source from where the bit is extracted. |
| Out (default output) | Is set true based on the value of the extracted bit pointed by BitNo. |
When operator is used inside a signal its default input is automatically tied to signal's InternalValue or previous operator's output. Its default output is automatically tied to next operator's input or to signal's Value. See also CDP Operator Usage In CDP Signals.
Actual Processing Code of the BitExtractOperator
unsigned int BitExtractOperator<T>::Process() { if (!d->bitNo) return STATUS_ERROR; this->m_output = ((static_cast<uint64_t>(this->m_input) & static_cast<uint64_t>(1 << static_cast<char>(*(d->bitNo)))) != 0); return STATUS_OK; }
