strToInt converts text that represents an integer into an Integer value for use in OCL expressions. Use it when a value is available as a string but the next part of your expression requires an Integer.
Result
strToInt returns an Integer whose value is equal to the string value of self.
If self does not represent an integer, the result is invalid. Handle or prevent non-integer input before relying on the converted value in a calculation, comparison, or other expression.
Examples
The following examples describe the conversion result:
| String value | Result |
|---|---|
| A string representing the integer 42 | The Integer 42
|
| A string that does not represent an integer | invalid
|
For example, use strToInt when a string-valued field contains an integer that you need to compare with another Integer value. Do not use the result as though it were a valid Integer when the source string may contain non-integer text.
Related conversion operators
strToInt and toInteger both describe conversion to an Integer. Use the operator that matches the type and expression form you are working with.
