STRING EXCLUDES¶
Checks whether a string (haystack) does NOT contain a given substring (needle), returning a boolean-like scalar result. Use this worker in workflow branching or validation steps where a condition must confirm the absence of a specific pattern or token in a string.
When to use¶
Classification: process.
Tagged: contains, excludes, filter, process, scalar, search, string, substring.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Haystack | haystack | scalar | — | ✓ | The source string to search within; provide any plain-text scalar value that will be tested for the absence of the needle substring. |
| Needle | needle | scalar | — | ✓ | The substring to look for in the haystack; if this string is NOT found in the haystack, the worker returns a truthy result. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| string_excludes_output_1 | string_excludes_output_1 | scalar | Boolean-like scalar (true/false or 1/0) indicating whether the haystack does NOT contain the needle; true means the needle is absent. |
