callFunction

protected <T> T callFunction(Adapter<T> runtime,
                             List<FunctionArgument<T>> arguments)

Description copied from class: BaseFunction

Called from BaseFunction.call(io.burt.jmespath.Adapter<T>, java.util.List<io.burt.jmespath.function.FunctionArgument<T>>) after the argument constraints have been checked against the arguments.

May perform additional type checking and throw ArgumentTypeException. For example when using expressions there is currently no way to check the types produced by those expressions without running the function. Functions that accept expressions are responsible for checking the types of the values produced by those expressions.
