Introspection
The uvm_simple_lock_dap cannot support the standard UVM instrumentation methods ( copy , clone , pack and unpack ), due to the fact that they would potentially violate the access policy.
A call to any of these methods will result in an error.

- virtual function void do_unpack ( uvm_packer packer ) [source]
- virtual function void do_print ( uvm_printer printer ) [source]
Function- do_print
Provides a 'Simple Lock' Data Access Policy.
The 'Simple Lock' Data Access Policy allows for any number of 'sets', so long as the value is not 'locked'. The value can be retrieved using 'get' at any time.
The UVM uses this policy to protect the file name value in the uvm_text_tr_database.
