Technical Interview Questions and Answers :: C++

i. A framework to be of significant use, it must provide more structure and much more services than this simple example do.
ii. A framework will also be supported by a library that provides classes that are useful for the application programmer when specifying the action classes.

An interface class that controls access to another class or adjusts its interface and is sometimes called as wrapper.

These issues is to separate a single object into two parts.
i. A handle providing the user interface.
ii. A representation holding all or most of the object’s state.

The connection between the handle and the representation is typically a pointer to the handle.

A handle that provides an interface that is close to identical to the class for which it is a handle often called as proxy.

i. Idea is to have one handle class for a family of classes defined by a base class.
ii. Derivation from this base class can be a powerful technique.
iii. It appears to a node class and abstract types.

Overloading -> enables a handle to gain control and do some work on each access to an object.

An approach to the support of design and reuse is to provide code that establishes a common framework into which the application builder fits application specific code as building blocks. Such an approach is often called as application frameworks.
