Class StringFunction
java.lang.Object
com.api.jsonata4java.expressions.functions.FunctionBase
com.api.jsonata4java.expressions.functions.StringFunction
From 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"]
$string([1..5])=="[1,2,3,4,5]"
