IsEmpty Operator - Haufe-Lexware/haufe.no-frills-transformation GitHub Wiki

The IsEmpty operator returns boolean true if the input parameter is an empty string.

What	Type
Syntax	IsEmpty(a)
a	any
Return type	string

In principle, this is short for Equals(param1, ""), but looks more readable.

Example: If(IsEmpty($email), "No EMail available", "mailto:" + $email)
