Typing functions

Object.as[type:string]→Object

Result: The As function only provides a reference for the type inference mechanism. The result of the expression is considered to be of type <type>. As is ignored in the actual formula evaluation.

Object.IfIs[Type:String;Then:Expression;Else:Expression]→Object

Result: Type distinction. If the object is of type "Type", the "Then" expression is applied to the object with the IfIs function, otherwise the "Else" expression is applied and the corresponding result is returned. At the same time, the type definition in the "Then" branch indicates that the object has the specified type and, if applicable, in the "Else" branch that the object does not have the specified type.

Object.Is[Type:String]→Βoolean

Result: The Is function tests whether the object corresponds to the specified type.
