Se 350 - Delegation & Strategy Design Patterns

Front 1

Makes use of "implementation" classes that encapsulate interface implementations used by many implementers

Back 1

True

Front 2

Helps to reduce application errors by centralizing common data values and removing the chance that an individual object may change its own version of "type" based data

Back 2

False

Front 3

Multiple implementation classes can be created when a variety of algorithms are needed to handle interface behaviors

Back 3

True

Front 4

Defines one or more static methods that encapsulate the details of object creation

Back 4

False

Front 5

Allows implementation objects to be changed dynamically during application execution depending upon conditions

Back 5

True

Front 6

Makes extensive use of "static" data members, resulting in a situation where multiple objects can be created that all share the same data values

Back 6

False (Singleton)

Front 7

Helps to reduce the space needed by a set of objects by removing the need to store duplicate objects containing the same data values

Back 7

False

Front 8

Specifies simple data objects made up of public data attributes containing copies of key data of the domain object

Back 8

False

Front 9

Results in a set of loosely coupled interchangeable, extensible, maintainable, and reusable parts

Back 9

True

Front 10

Allow clients to make a single call to retrieve multiple data elements of a domain object

Back 10

False (DTO)
