  - castString
```
public static String castString(com.fasterxml.jackson.databind.JsonNode node,

                         throws EvaluateRuntimeException
```
    Encodes JSONata string casting semantics. See http://docs.jsonata.org/string-functions.html: $string(arg) Casts the arg parameter to a string using the following casting rules Strings are unchanged Functions are converted to an empty string Numeric infinity and NaN throw an error because they cannot be represented as a JSON number All other values are converted to a JSON string using the JSON.stringify function If arg is not specified (i.e. this function is invoked with no arguments), then the context value is used as the value of arg. Examples $string(5) == "5" [1..5].$string() == ["1", "2", "3", "4", "5"]
    
    Parameters:
    
    node - JsonNode whose content is to be cast as a String
    
    prettify - Whether the objects or arrays should be pretty printed
    
    Returns:
