The default implementation of Object.clone() performs a shallow copy. When a class desires a deep copy or some other custom behavior, they must implement that in their own clone() method after they obtain the copy from the superclass. The syntax for calling clone in Java is (assuming obj is a variable of a class type that has a public clone ...
In VBA, an assignment of variables of type Object is a shallow copy, an assignment for all other types (numeric types, String, user defined types, arrays) is a deep copy. So the keyword Set for an assignment signals a shallow copy and the (optional) keyword Let signals a deep copy. There is no built-in method for deep copies of Objects in VBA.
In order to function as a JavaBean class, an object class must obey certain conventions about method naming, construction, and behaviour. These conventions make it possible to have tools that can use, reuse, replace, and connect Java Beans. The required conventions are as follows: The class must have a public default constructor (with no ...
CORBA Interface Definition Language provides the mechanism to ensure that user-code conforms to method-names, return-, parameter-types, and exceptions. High tunability Many implementations (e.g. ORBexpress (Ada, C++, and Java implementation) [ 6 ] and OmniORB (open source C++ and Python implementation)) [ 7 ] have options for tuning the ...
BeanShell is a small, free, embeddable Java source interpreter with object scripting language features, written in Java. It runs in the Java Runtime Environment (JRE), dynamically executes standard Java syntax and extends it with common scripting conveniences such as loose types, commands, and method closures, like those in Perl and JavaScript.
Applets: java.applet allows applications to be downloaded over a network and run within a guarded sandbox; Java Beans: java.beans provides ways to manipulate reusable components. Introspection and reflection: java.lang.Class represents a class, but other classes such as Method and Constructor are available in java.lang.reflect.

A name is bound to an object in the directory by storing either the object or a reference to the object in the directory service identified by the name.
