  6. final def defaultRearrange(functionSignature: FunctionSignature, args: Seq[Expression], functionName: String): Seq[Expression]

    This method is the default routine which rearranges the arguments in positional order according to the function signature provided.

    This method is the default routine which rearranges the arguments in positional order according to the function signature provided. This will also fill in any default values that exists for optional arguments. This method will also be invoked even if there are no named arguments in the argument list. This method will keep all positional arguments in their original order.

    functionSignature

    The function signature that defines the positional ordering

    args

    The argument list provided in function invocation

    functionName

    The name of the function

    returns

    A list of arguments rearranged in positional order defined by the provided signature

  16. def splitAndCheckNamedArguments(args: Seq[Expression], functionName: String): (Seq[Expression], Seq[NamedArgumentExpression])

    This method splits named arguments from the argument list.

    This method splits named arguments from the argument list. Also checks if: - the named arguments don't contains positional arguments once keyword arguments start - the named arguments don't use the duplicated names

    args

    The argument list provided in function invocation

    returns

    A tuple of a list of positional arguments and a list of keyword arguments
