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

The False and True operators do not take any parameters and simply returns a boolean false or true.

This may be useful when creating custom operators for checking more complicated rules, e.g. for validation.

Example:

<CustomOperator name="IsValid" paramCount="0" returnType="bool">
  <Parameters />
  <Switch>
    <Case condition='$Name="<undefined>"'>False()</Case>
    <Case condition='IsEmpty($Name)'>False()</Case>
    <Otherwise>True()</Otherwise>
  </Switch>
</CustomOperator>

Not that this custom operator does not have any parameters, but simply uses the $Name field directly.
