Chapter 11 - OpenDoc Runtime Features
This chapter concludes the programming portion of this book by discussing several aspects of the OpenDoc runtime environment that are of interest to you as a part-editor developer. The topics in this chapter are different from the programming-interface topics discussed in the previous eight chapters. Nevertheless, they are important to understanding how your parts function at runtime with OpenDoc.
- "The Runtime Environment" describes in general the runtime architecture of OpenDoc and its effect on part development.
- "Creating and Releasing Objects" describes how your part editor creates and releases objects (including how to be efficient about it), how it manages multiple references to objects, and when it should purge memory.
- "Accessing Objects Through Iterators" describes how your part can use iterators to access collections of objects.
- "Binding" describes how your part editor is bound to a part at runtime according to the kinds of data stored in the part and the kinds and categories of data supported by your editor.
- "Runtime Object Relationships" summarizes and illustrates how OpenDoc objects in a document interact with each other for specific purposes.
- "The Document Shell" describes how the OpenDoc document shell performs its functions and how its functioning relates to your part editor's responsibilities.
