如何通过uvm工厂填充动态数组

class my_object extends uvm_object;
  rand int my_array[];

  // ...

  function new(string name = "my_object");
    super.new(name);
  endfunction

  // ...

  function void post_randomize();
    super.post_randomize();

    // 在这里可以对动态数组进行进一步操作

    $display("my_array: %p", my_array);
  endfunction
endclass

class my_factory extends uvm_factory;
  `uvm_object_utils(my_factory)

  function my_object create_my_object();
    my_object obj = new();
    obj.my_array = new[10];

    // 在这里可以填充动态数组

    return obj;
  endfunction
endclass

module test;
  initial begin
    my_factory factory;
    my_object obj;

    factory = my_factory::get();
    factory.set_type_override(my_object::get_type(), my_factory::get_type());

    obj = my_object::type_id::create("obj");
    $display("Created object: %p", obj);
  end
endmodule
