formulaFromString
formulaFromString( formulaString : string ) : 4D.Function
| Parameter | Type | Description | |
|---|---|---|---|
| formulaString | string | → | string formula to be returned as object |
| Result | 4D.Function | ← | Native object encapsulating the formula |
Description
The formula from string command creates a 4D.Function object based upon formulaString. The formulaString expression can be as simple as a single value or complex, such as a project method with parameters.
This command is similar to formula, except that it handles a text-based formula. In most cases, it is recommended to use the formula command. formulaFromString should only be used when the original formula was expressed as text (e.g., stored externally in a JSON file).
note
This command does not support the use of variables in formulaString. An attempt to access a variable with formulaFromString will result in an error (-10737).
