public abstract class Values
extends Object
```
Utility for wrapping regular Java types and exposing them as Value objects, and vice versa. The long set of ofXXX methods in this class are meant to be used as arguments for methods like Value.asList(Function), MapAccessor.asMap(Function), Record.asMap(Function) and so on.

    Helper function for creating a map of parameters, this can be used when you run statements.
    Allowed parameter types are:
    - Integer
    - Long
    - Boolean
    - Double
    - Float
    - String
    - Map with String keys and values being any type in this list
    - Collection of any type in this list
    Parameters:
    keysAndValues - alternating sequence of keys and values
    
    Returns:
    Map containing all parameters specified

    StatementRunner.run(String, Value)
  - ofValue
```
public static Function<Value,Value> ofValue()
```
    The identity function for value conversion - returns the value untouched.
    
    Returns:
    a function that returns the value passed into it - the identity function
  - ofObject
```
public static Function<Value,Object> ofObject()
```
    Converts values to objects using Value.asObject().
    
    Returns:
    a function that returns Value.asObject() of a Value
  - ofNumber
```
public static Function<Value,Number> ofNumber()
```
    Converts values to Number.
    
    Returns:
    a function that returns Value.asNumber() of a Value
  - ofString
```
public static Function<Value,String> ofString()
```
    Converts values to String. If you want to access a string you've retrieved from the database, this is the right choice. If you want to print any value for human consumption, for instance in a log, ofToString() is the right choice.
    
    Returns:
    a function that returns Value.asString() of a Value
  - ofToString
```
public static Function<Value,String> ofToString()
```
    Converts values using Value.toString(), a human-readable string description of any value. This is different from ofString(), which returns a java String value from a database TypeSystem.STRING(). If you are wanting to print any value for human consumption, this is the right choice. If you are wanting to access a string value stored in the database, you should use ofString().
    
    Returns:
    a function that returns Value.toString() of a Value
  - ofInteger
```
public static Function<Value,Integer> ofInteger()
```
    Converts values to Integer.
    
    Returns:
    a function that returns Value.asInt() of a Value
  - ofLong
```
public static Function<Value,Long> ofLong()
```
    Converts values to Long.
    
    Returns:
    a function that returns Value.asLong() of a Value
  - ofFloat
```
public static Function<Value,Float> ofFloat()
```
    Converts values to Float.
    
    Returns:
    a function that returns Value.asFloat() of a Value
  - ofDouble
```
public static Function<Value,Double> ofDouble()
```

```
    Converts values to Map.
    
    Returns:
    a function that returns MapAccessor.asMap() of a Value
  - ofMap
```
