public class UtilFunctionExecutorImpl
extends Object
implements UtilFunctionExecutor

Utility function executor is a helper class for executing utility functions. It consists of built-in functions.

Includes a map of function implementations, where key is the method name and value is the function implementation instance. It also includes the type converter to convert different types of input to the expected type.

Makes use of two indexes to manage function arguments - one for rest arguments and one for path arguments.
