kind - class to generate

argument - argument for constructor of that class

Returns:

new generated Argument

Throws:

ArgumentException - if creation failed

IllegalArgumentException - if creation failed because of a programming error

readArgument

public static final Argument readArgument(TextInput input,
                                          Map string2class,
                                          ParsingTable parsing)
                                   throws ParsingException

Create an Argument out of an TextInput object.

Parameters:

input - source to read from

string2class - use this mapping for parsing

parsing - for saving positions of created arguments

Returns:

created argument

Throws:

ParsingException - if creation failed

readArgumentList

private static final Argument[] readArgumentList(TextInput input,
                                                 Map string2class,
