You can use ToUpper() in an OCL expression to return an uppercase version of a string; use it when you need text in uppercase in an expression result.

Syntax

<string>.ToUpper()

Example

The following expression returns the text with its characters converted to uppercase:

'Hello World'.ToUpper()

Result:

'HELLO WORLD'

Use with an attribute

If self.Name contains 'Ada Lovelace', use:

self.Name.ToUpper()

The expression returns 'ADA LOVELACE'.

Related string operations

Use ToLower() when you need lowercase text instead. Use asString when the value is not already a string and you need its string representation before applying string operations.
