UVM agent classes are implemented as subclasses of the uvm_agent class, which itself is a subclass of uvm_component. Much like uvm_scoreboard, uvm_agent is lightweight in terms of class methods. Its only class methods are the "new" constructor and the "get_is_active" method. If the agent is being used to drive ports, get_is_active returns UVM ...
The resulting object is called an object copy or simply copy of the original object. Copying is basic but has subtleties and can have significant overhead. There are several ways to copy an object, most commonly by a copy constructor or cloning. Copying is done mostly so the copy can be modified or moved, or the current value preserved.
When using polymorphism, one sometimes needs to create copies of objects by the base class pointer. A commonly used idiom for this is adding a virtual clone function that is defined in every derived class. The CRTP can be used to avoid having to duplicate that function or other similar functions in every derived class.
In Java, the Object class contains the clone() method, which copies the object and returns a reference to that copied object. Since it is in the Object class, all classes defined in Java will have a clone method available to the programmer (although to function correctly it needs to be overridden at each level it is used). Cloning an object in ...
In computer programming, particularly object-oriented programming, cloning refers to object copying by a method or copy factory function, often called clone or copy, as opposed to by a copy constructor. Cloning is polymorphic, in that the type of the object being cloned need not be specified, in contrast to using a copy constructor, which ...
In the thermodynamics of equilibrium, a state function, function of state, or point function for a thermodynamic system is a mathematical function relating several state variables or state quantities (that describe equilibrium states of a system) that depend only on the current equilibrium thermodynamic state of the system [1] (e.g. gas, liquid, solid, crystal, or emulsion), not the path which ...

The class Object's clone() method creates and returns a copy of the object, with the same class and with all the fields having the same values. However, Object.clone() throws a CloneNotSupportedException unless the object is an instance of a class that implements the marker interface Cloneable. The default implementation of Object.clone ...
