Implementation of the argument list processor.


Interfaces

public interface argument_list

Constructor for the argument list

  • private function new_argument_list(argument_counter, argument_getter) result(new)

    Constructor of the argument list

    Arguments

    Type IntentOptional Attributes Name
    procedure(argument_count_interface), optional :: argument_counter

    Argument counter interface
    procedure(get_argument_interface), optional :: argument_getter

    Argument getter interface

    Return Value type(argument_list)

    Newly created argument list

public interface len

  • private pure function get_length(self) result(length)

    Arguments

    Type IntentOptional Attributes Name
    class(argument_list), intent(in) :: self

    Return Value integer


Abstract Interfaces

abstract interface

  • public function argument_count_interface() result(argument_count)

    Interface of the argument counter

    Arguments

    None

    Return Value integer

    Number of available arguments

abstract interface

  • public subroutine get_argument_interface(idx, arg)

    Interface of the argument getter

    Arguments

    Type IntentOptional Attributes Name
    integer, intent(in) :: idx

    Index of the argument to retrieve, range 0 to argument_counter()
    character(len=:), intent(out), allocatable :: arg

    Returned argument payload, allocation status is used to signal errors
