CX_NAMED_FORMULA

Class hierarchy
Description:

A CX_NAMED_FORMULA behaves like a CX_FORMULA, but with an additional data field "Name".

Code example: 
// Formel erzeugen
Var(formula)   CreateTransObject(CX_NAMED_FORMULA) -> formula
"MY_FORMULA" formula Put(name)
"if (available(x)) x + 0.5cm else y - 3.3cm" formula PutData

List of methods (MDI)
Function MA* Parameters Return Brief description
Add CX_AMOUNT CX_AMOUNT Operator + as function
AddAssign CX_AMOUNT Operator += as function
Amount OBJECT Evaluate the formula Return the value of the result object
AmountWeak CX_AMOUNT
Car format INTEGER, INTEGER CX_AMOUNT Returns a formatted object according to the given number of digits before and after the decimal point (only with CX_VALUE, otherwise the object itself).
DivAssign CX_AMOUNT Operator /= as function
Divide CX_AMOUNT CX_AMOUNT Operator / as function
Evaluate OBJECT Evaluate the formula
Evaluate1 OBJECT Evaluation of the formula, unbound variable leads to error
Evaluate2 OBJECT Evaluation of the formula, for unbound variables the result is 0.0 (CX_NUMERIC)
Evaluate3 OBJECT Evaluate the formula, unbound variables arequeried with SendMsg / Waitoninputif no InstantView® message is logged in: error .
Evaluate4 OBJECT Evaluation of the formula, for unbound variables an object corresponding to the type with value zero is included in the calculation.
EvaluateWeak OBJECT Evaluation of the formula condition, as with Evaluate1, errors are written to a CX_VESSEL object
GetInputAccessPaths
233188		 VECTOR&lmt;STRING>Returns all access paths of this formula
GetInputVarNames (OBJECT) VECTOR&lmt;STRING> returns the names of all variables required for the calculation of the formula, if a container object is specified, the corresponding dynamic data fields are created in this object
MulAssign CX_AMOUNT Operator *= as function
Multiply CX_AMOUNT CX_AMOUNT Operator * as function
RawFormula STRING Formula in string form
SetMessage (INTEGER) Register InstantView® message (for Evaluate3)
ShowIPN STRING Displaying the formula in the IP notation
SubAssign CX_AMOUNT Operator -= as function
Subtract CX_AMOUNT CX_AMOUNT Operator - as a function
XML export STRING Formula in XML (local character set) form
XML exportUTF8 STRING Formula in the XML form (UTF-8)

Function Parameters Return Brief description
available (OBJECT) OBJECT tests whether the variable specified as a parameter (i.e. a dynamic data field or an access expression) is bound In contrast to has(...) the variable is loosely bound (the normal case).
get (OBJECT) OBJECT calls for the variable to be closely linked.
has (OBJECT) OBJECT tests whether the variable specified as a parameter (i.e. a dynamic data field or an access expression) is bound, whereby the variable is bound closely (see function get)
inherited (OBJECT, OBJECT) OBJECT tests whether the object designated with variable is derived from the class designated with the second parameter. The name of a class can be specified as a parameter (type constant)
type (OBJECT) OBJECT returns the type of a variable. The result can be compared with a type constant.
var (OBJECT) OBJECT returns the value of an InstantView® variable whose name must be specified as a parameter. var(...) can also be placed at the beginning of an access expression.
