Warning: this class is part of the Rakudo implementation, and is not a part of the language specification.
A Metamodel::ParametricRoleHOW
represents a non-instantiated, possibly parameterized, role:
([::T] ).HOW.say;# OUTPUT: «Perl6::Metamodel::ParametricRoleHOW.new»( ).HOW.say; # OUTPUT: «Perl6::Metamodel::ParametricRoleHOW.new»
As usual, .new_type
will create a new object of this class.
my \zipi := Metamodel::ParametricRoleHOW.new_type( name => "zape", group => "Zape");say zipi.HOW; # OUTPUT: «Perl6::Metamodel::ParametricRoleHOW.new»
The extra group
argument will need to be used to integrate it in a parametric role group, which will need to be defined in advance.
Note: As most of the Metamodel
classes, this one is here mainly for illustration purposes and it's not intended for the final user to instantiate, unless their intention is really to create a parametric role group.
