UR::Object::Command::List::Style3pm

subject_class_name (optional)

The subject_class_name is the class for which the objects will be fetched. It can be specified one of two main ways:

by_the_end_user_on_the_command_line

For this do nothing, the end user will have to provide it when the command is run.

by_the_developer_in the_class_declartion

For this, in the class declaration, add a has key w/ arrayref of hashrefs. One of the hashrefs needs to be subject_class_name. Give it this declaration:

 class MyFetchAndDo {
     is => 'UR::Object::Command::FetchAndDo',
     has => [
         subject_class_name => {
             value => <CLASS NAME>,
             is_constant => 1,
         },
     ],
 };

show (optional)

Add defaults to the show property:

 class MyFetchAndDo {
     is => 'UR::Object::Command::FetchAndDo',
     has => [
         show => {
             default_value => 'name,age', 
         },
     ],
 };
