Enclosing class:

CalculatorExpr
```
protected static class CalculatorExpr.Operators
extends java.lang.Object
```
This class contains all Operators as static references. The operations are protected only to show it as documentation. They are used private only. To use this operators: The CalculatorExpr.setExpr(String) converts a string given expression in the internal form which uses this operations, respectively the SetExpr converts an expression from ZBNF TODO Idea-typedOperator: this class may be an interface instead, which is implemented for the known CalculatorExpr.ExpressionType. Then the switch-case can be saved in calculation time.

  - cmpEqOperation
```
protected static final CalculatorExpr.Operator cmpEqOperation
```
    Compares the arg with the accu. Set the accu to true if accu == arg2 before the operation. Returns a CalculatorExpr#booleanExpr. throws an IllegalArgumentException "unknown Type" on String or Object types.
  - cmpNeOperation
```
protected static final CalculatorExpr.Operator cmpNeOperation
```
    Compares the arg with the accu. Set the accu to true if accu != arg2 before the operation. Returns a CalculatorExpr#booleanExpr. throws an IllegalArgumentException "unknown Type" on String or Object types.
  - cmpLessThanOperation
```
protected static final CalculatorExpr.Operator cmpLessThanOperation
```
    Compares the arg with the accu. Set the accu to true if accu < arg2 before the operation. Returns a CalculatorExpr#booleanExpr. throws an IllegalArgumentException "unknown Type" on String or Object types.
  - cmpGreaterEqualOperation
```
protected static final CalculatorExpr.Operator cmpGreaterEqualOperation
```
    Compares the arg with the accu. Set the accu to true if accu >= arg2 before the operation. Returns a CalculatorExpr#booleanExpr. throws an IllegalArgumentException "unknown Type" on String or Object types.
  - cmpGreaterThanOperation
```
protected static final CalculatorExpr.Operator cmpGreaterThanOperation
```
    Compares the arg with the accu. Set the accu to true if accu > arg2 before the operation. Returns a CalculatorExpr#booleanExpr. throws an IllegalArgumentException "unknown Type" on String or Object types.
  - cmpLessEqualOperation
```
protected static final CalculatorExpr.Operator cmpLessEqualOperation
```
    Compares the arg with the accu. Set the accu to true if accu <= arg2 before the operation. Returns a CalculatorExpr#booleanExpr. throws an IllegalArgumentException "unknown Type" on String or Object types.
  - cmpContainsOperation
```
protected static final CalculatorExpr.Operator cmpContainsOperation
```
    Check whether the String in accu contains the String in arg. Set the accu to true if the String in the second argument is containing in the String in accu. Returns a CalculatorExpr#booleanExpr. throws an IllegalArgumentException "unknown Type" on String or Object types.
  - cmpStartsOperation

    Check whether the String in accu ends with the String in arg. Set the accu to true if the String in the accu ends with the the String in arg. Returns a CalculatorExpr#booleanExpr. throws an IllegalArgumentException "unknown Type" on String or Object types.
  - boolAndOperation
```
protected static final CalculatorExpr.Operator boolAndOperation
```
    Ands the arg with the accu. Converts the argument to boolean if they are not boolean using CalculatorExpr.Value.booleanValue(). Returns a CalculatorExpr#booleanExpr.
  - boolOrOperation
```
protected static final CalculatorExpr.Operator boolOrOperation
```
    Ors the arg with the accu. Converts the argument to boolean if they are not boolean using CalculatorExpr.Value.booleanValue(). Returns a CalculatorExpr#booleanExpr.
  - boolCheckAndOperation
```
protected static final CalculatorExpr.Operator boolCheckAndOperation
```
    Ands the arg with the accu. Converts the argument to boolean if they are not boolean using CalculatorExpr.Value.booleanValue(). Returns a CalculatorExpr#booleanExpr if the accu is true respectively a CalculatorExpr#finishBooleanExpr if the accu is false. In the last case all other And operations cannot change the result, therefore they are not executed.
  - boolCheckOrOperation
```
protected static final CalculatorExpr.Operator boolCheckOrOperation
```
    Ors the arg with the accu. Converts the argument to boolean if they are not boolean using CalculatorExpr.Value.booleanValue(). Returns a CalculatorExpr#booleanExpr if the accu is false respectively a CalculatorExpr#finishBooleanExpr if the accu is true. In the last case all other Or operations cannot change the result, therefore they are not executed.
  - concatStringOperation
```
protected static final CalculatorExpr.Operator concatStringOperation
```
    Concatenate the given String with the accu. The accu should contain a CalculatorExpr.Value.stringVal from the operation before (initialize with a String). The CalculatorExpr.Value.stringVal is changed from any CharSequenceence to StringBuilder to append the value from given arg, whereby the arg value is converted to CalculatorExpr.Value.stringValue() to convert a numeric or any Object to a String to concatenate.
  - cmpInstanceofOperation
```
protected static final CalculatorExpr.Operator cmpInstanceofOperation
```
    Checks whether the accu is a instance of the given class. The arg of the operate have to be of type java.lang.Class with the instance of the checked type. If the arg is one of the Boxing types for the primitives the operate method returns true if the type in the accu matches to that given boxing type though it is given as simple value, not as boxed, too.
  - setOperation
```
protected static final CalculatorExpr.Operator setOperation
```
    Sets the given value to the accu.
  - assignOperation
```
protected static final CalculatorExpr.Operator assignOperation
```
    Assign the current value to the left variable. This is not useable currently because the values are not addresses. Write back never required. It is only to complete a possible test. Later improve.
