CalculatorExpr.Operation

- org.vishia.util.CalculatorExpr.Operation

Enclosing class:

CalculatorExpr
```
public static class CalculatorExpr.Operation
extends java.lang.Object
```
An Operation in the list of operations. It contains the operator and maybe an operand.
- The operator_ operates with the CalculatorExpr#accu, the Operation#value and maybe the CalculatorExpr#stack.
- An unary operator will be applied to the accu firstly.
- The operand may be given as constant value, then it is stored with its type in #value.
- The operand may be given as index to the given input variables for expression calculation. Then #ixVariable is set >=0
- The operand may be referenced in top of stack, then kindOperand = -2
- The operand may be gotten from any java object, then datapath() is set.
