Properties

	Name	Description
	ArgumentNames	List of the function argument names.
	ArgumentTypes	List of the function argument types.
	Body	Body of the function.
	CalledOnNullInput	Determines if the function is called when the input is null.
	Deterministic	Indicates whether or not this function is deterministic. This means that given a particular input, the function will always produce the same output.
	KeyspaceName	Name of the keyspace where the CQL function is declared.
	Language	Name of the programming language, for example: java, javascript, ...
	Monotonic	Indicates whether or not this function is monotonic on all of its arguments. This means that it is either entirely non-increasing or non-decreasing. Even if the function is not monotonic on all of its arguments, it's possible to specify that it is monotonic on one of its arguments, meaning that partial applications of the function over that argument will be monotonic.
	MonotonicOn	The argument names that the function is monotonic on. If Monotonic is true, this will return all argument names. Otherwise, this will return either one argument or an empty collection.
	Name	Name of the CQL function.
	ReturnType	Type of the return value.
	Signature	Signature of the function.
