Bool Operation¶
Performs basic boolean logic between two boolean inputs. Supports AND, OR, XOR between a and b, and a unary NOT that inverts a. Returns a single boolean result.
Usage¶
Use this node when you need to combine or invert boolean flags in a workflow, such as gating execution, selecting branches, or building compound conditions. Choose the desired operation via the op selector; for NOT, only the first input (a) is used.
Inputs¶
| Field | Required | Type | Description | Example |
|---|---|---|---|---|
| a | True | BOOLEAN | First boolean operand. Used by all operations and the sole input for NOT. | True |
| b | True | BOOLEAN | Second boolean operand. Ignored when op is NOT a. | False |
| op | True | enum | The boolean operation to apply. Options: a AND b, a OR b, a XOR b, NOT a. | a AND b |
Outputs¶
| Field | Type | Description | Example |
|---|---|---|---|
| result | BOOLEAN | The boolean outcome of the selected operation. | False |
Important Notes¶
- For NOT a, the b input is ignored.
- XOR returns true only when exactly one of a or b is true.
- If an unknown operation is provided or an error occurs, the node returns false.
- Inputs must be boolean values; passing non-boolean types may lead to unintended results.
Troubleshooting¶
- Result is always false: Verify the op value matches one of the allowed options and that both inputs are valid booleans.
- Unexpected use of b with NOT: Ensure you understand that NOT a ignores b.
- XOR behaving like OR: Remember XOR is exclusive; it returns true only when a and b differ.
- Type errors or coercion issues: Make sure upstream nodes output BOOLEAN, not strings like "true" or "false".
