import static java.lang.annotation.ElementType.FIELD;


When applied to a field all of its child fields annotated with Parameter will be included during arguments parsing.


Mainly useful when creating complex command based CLI interfaces, where several commands can share a set of arguments, but using object inheritance is not enough, due to no-multiple-inheritance restriction. Using ParametersDelegate any number of command sets can be shared by using composition pattern.


Delegations can be chained (nested).
