Software Engineering S15 Object-Oriented Development

Front 1

OOA

Back 1

OOA is concerned with developing an object model of the application domain.

Front 2

OOD

Back 2

OOD is concerned with developing an object-oriented system model to implement requirements.

Front 3

Major Benefit of Obj. Oriented Development

Back 3

The developer thinks under the same conceptual framework throughout the entire development life cycle.

Front 4

(In OOP) Interactions among objects take place via ______ ______

Back 4

message passing

Front 5

object (formal defn)

Back 5

An object is an entity which has a state and a defined set of operations which operate on that state.

Front 6

The class at the top level (having no superclass) is called the ______ class

Back 6

root class (e.g., the class 'Object' in Java)

Front 7

Characteristics (attributes) of an object are represented by ________s

Back 7

variables (attributes)

Front 8

2 types of methods

Back 8

class methods (static methods; functions),
instance methods

Front 9

All instantiated objects communicate with each other via _____ ________

Back 9

message passing

Sending a message to an object == invoking one of the receiving object's methods

square.getArea() would be sending a message to the square object

Generally said:
"send message M to object A"
("send getArea() to square")
not
"send a message to object A to invoke its method M"

Front 10

object references

Back 10

Objects are identified by their unique addresses internally maintained by the implementation programming language. They are called object references. An object reference uniquely identifies the object which will receive the message.

Front 11

Encapsulation

Back 11

Encapsulation means that a consumer sees only the services that are available from an object, but not how those services are implemented.

Better defns (also abstraction, information hiding):

Front 12

Polymorphism - static typing vs. dynamic typing

Back 12

static polymorphism = method overloading
dynamic polymorphism = method overriding

Front 13

Polymorphism

Back 13

Polymorphism refers to the ability of an object to assume more than
one form or to be a member of more than one class.

Front 14

dynamic binding

Back 14

Dynamic Binding implies that the implementation code executed in responding to a particular message in the source code is not known at compile time, and is dispatched at run time depending on the form of the polymorphic object that receives the message.

Front 15

association

Back 15

in UML, denoted by "is-member-of", "is-managed-by", etc.

Associations are general but may indicate that an attribute of an object is an associated object or that a method relies on an associated object.
