Questions and Answers

What is the primary goal of using an adapter in the context of the stock market app?

  • To improve the performance of the analytics library
  • To display nice-looking charts and diagrams for the user
  • To convert the interface of the analytics library to work with XML data (correct)

  • The library is not scalable
  • The library is not maintained by the app developers
  • The library expects data in a format that's incompatible with the app (correct)
  • The library is not efficient
  • What is the term for the object that an adapter wraps to hide the complexity of conversion?

    Study Notes

    Integrating a 3rd-Party Analytics Library

    • A 3rd-party analytics library may not be compatible with an app due to differences in data format (e.g., JSON vs. XML).
    • Modifying the library's source code may not be possible or desirable, especially if it breaks existing code.

    Problem Scenario: Stock Market Monitoring App

    • An app downloads stock data from multiple sources in XML format and displays charts and diagrams for the user.
    • Integrating a 3rd-party analytics library that only works with JSON data is problematic.

    Solution: Adapter Pattern

    • An adapter is a special object that converts the interface of one object to make it compatible with another object.
    • Adapters can convert data formats (e.g., meters to imperial units) and facilitate collaboration between objects with different interfaces.
    • Adapters work by wrapping one object to hide the complexity of conversion, without the wrapped object being aware of the adapter.

    Two-Way Adapters

    • Two-way adapters can convert calls in both directions, enabling bi-directional communication between objects.

    XML-to-JSON Adapter for the Analytics Library

    • Create an adapter for each class of the analytics library that the app works with directly.
    • The adapter translates incoming XML data into a JSON structure and passes the call to the appropriate methods of the wrapped analytics object.
    • The app communicates with the library only via these adapters, enabling seamless integration despite incompatible data formats.
