Container Classes
The container classes are type parameterized data structures. The uvm_queue #(T) class implements a queue datastructure similar to the SystemVerilog queue construct. And the uvm_pool #(KEY,T) class implements a pool datastructure similar to the SystemVerilog associative array. The class based data structures allow the objects to be shared by reference; for example, a copy of a uvm_pool #(KEY,T) object will copy just the class handle instead of the entire associative array.
