how to pass value to a variable that is a derivation of uvm_object and not uvm_component

Hi,

problem statement: I wanted to set a value to a variable that is derived of a uvm_object. I wanted to use the get/.set method

prvious code snippet:

function new(int len = 0)

  if(len > 0)

    this.length = len;

  else

    ERROR

endfunction

Given that now the UVM constructor has to be like 

function new(string name ="");

  super.new(name);

endfunction

I wanted to set the len, variable using the set method.

1) however the set/get method requires a logical hierarchy, given that this object is instantiated in a sequence object, I don't know what which way can you pass the sequence_item hierarchy. 

2) Also given that the ojbect does not have phasing involved unless I pass the value in some function and call the function explicitly it doesn't seem like it will work.

I wanted to know if there is an elegant way to do so?

Thanks,

Ankur
