Hidden Gems Screencast: Object Persistence, Part One

Posted on in Categories Smalltalk

The purpose of the Hidden Gems Screencast is to give developers who use Cincom Smalltalk some valuable insight into the useful abilities of the products that may not be obvious.  In this month’s new screencast, Arden Thomas, the Cincom Smalltalk Product Manager, shares Part One of Object Persistence.

Object persistence is about saving and restoring the state of an object. This can be done in a variety of ways, often with a relational or object database. But what alternatives are there and how do they work? That is what this series will discuss, build and demonstrate.

Part One will demonstrate a simple, powerful and useful text-based technique that is not widely known.

Part One includes:

  • Creating a text-based representation of a large object
  • Saving the text-based format to a file
  • Re-creating the object from the file contents
  • Advantages/disadvantages discussion
