Syntax

	if($test, $then, $else)

$test ? $then : $else

Description

Returns the result of the evaluation of then or else depending on the evaluation of test. If the evaluation of test is true, then then is evaluated and the result is returned, otherwise else.

All of the above notations are equivalent. Alternative notation: ifElse.

For case distinctions where multiple conditions must be evaluated, there is the alternative switch syntax. This avoids the nesting of conditions and leads to a much better readability in this case.

Parameters

Name	Type	Description	Mandatory
test	Business object	An expression that returns `true` or `false` after evaluation.	yes
then	Business object	An expression that evaluates when `test` returns `true` .	yes
else	Business object	An expression that evaluates if `test` results in `false`.	yes

Return value

Type: Business object

The result of evaluating then or else, depending on the result of test.

Examples

Notation with "if

	{
  time = dateTime(2021, 9, 13, 15, 24);
  hour = $time.toSystemCalendar().hour();
  ($hour > 12).if("Nachmittag", "Vormittag")
}

Output: Nachmittag

The hour 13 is greater than 12, therefore the expression of "then" is output (note the time zone!).

Shortened notation

	{
  x = 16;
  ($x >= 18)? "Here is your alcohol": "No alcohol vor kids!";
}

Output: No alcohol for kids!

Since x is less than 18, the result of else is returned.
