Lazy Conditional¶
Evaluates up to 10 boolean conditions in order and returns the first corresponding value whose condition is true; otherwise returns the provided else value. Uses lazy evaluation so only the inputs needed for the selected branch are requested and computed.
Usage¶
Use this node to build multi-branch logic without computing all branches. Provide condition1 with its value1, then optionally add more condition/value pairs (up to 10), and an else value for the fallback. The node short-circuits at the first true condition, requesting only the inputs it needs.
Inputs¶
| Field | Required | Type | Description | Example |
|---|---|---|---|---|
| condition1 | False | BOOLEAN | First condition to test. If true, value1 will be returned. | True |
| value1 | False | WILDCARD | Value to return if condition1 is true. | Result A |
| condition2 | False | BOOLEAN | Second condition, evaluated only if condition1 is false. | False |
| value2 | False | WILDCARD | Value to return if condition2 is true. | Result B |
| condition3 | False | BOOLEAN | Third condition, evaluated only if prior conditions are false. | False |
| value3 | False | WILDCARD | Value to return if condition3 is true. | Result C |
| condition4 | False | BOOLEAN | Fourth condition. | False |
| value4 | False | WILDCARD | Value to return if condition4 is true. | Result D |
| condition5 | False | BOOLEAN | Fifth condition. | False |
| value5 | False | WILDCARD | Value to return if condition5 is true. | Result E |
| condition6 | False | BOOLEAN | Sixth condition. | False |
| value6 | False | WILDCARD | Value to return if condition6 is true. | Result F |
| condition7 | False | BOOLEAN | Seventh condition. | False |
| value7 | False | WILDCARD | Value to return if condition7 is true. | Result G |
| condition8 | False | BOOLEAN | Eighth condition. | False |
| value8 | False | WILDCARD | Value to return if condition8 is true. | Result H |
| condition9 | False | BOOLEAN | Ninth condition. | False |
| value9 | False | WILDCARD | Value to return if condition9 is true. | Result I |
| condition10 | False | BOOLEAN | Tenth condition. | False |
| value10 | False | WILDCARD | Value to return if condition10 is true. | Result J |
| else | False | WILDCARD | Fallback value if none of the conditions are true. | Default Result |
Outputs¶
| Field | Type | Description | Example |
|---|---|---|---|
| value | WILDCARD | The selected value based on the first true condition, or the else value if none are true. | Result B |
Important Notes¶
- Order matters: conditions are evaluated from 1 to 10 and the first true one wins.
- Lazy evaluation: only the inputs necessary for the selected branch are requested and computed.
- Provide pairs: for any conditionX that can be true, ensure valueX is also provided; otherwise the node will request it.
- Fallback recommended: provide an else value to avoid a None output when no conditions are true.
- Type flexibility: value inputs are WILDCARD; ensure downstream nodes can handle the type that may be output.
- Maximum branches: supports up to 10 condition/value branches.
Troubleshooting¶
- Node keeps asking for inputs: Ensure each conditionX that might be true has a corresponding valueX, and provide an else value.
- Unexpected None output: Add or connect an else value, or verify that at least one true condition has its value connected.
- Downstream type errors: Standardize the types of valueX and else so the selected output matches what downstream nodes expect.
- Multiple true conditions choose the wrong branch: Remember only the first true condition in order 1..10 is used. Reorder conditions accordingly.
- No output changes when toggling conditions: Verify that the condition you toggle precedes any other true condition; otherwise a prior true condition will short-circuit.
