Chapter 1. Basic concepts, classes, and facilities


Authors: The Ptolemy Team
This section describes some basic classes and low-level concepts that are used throughout Ptolemy. There are a number of iterator classes, all with the same interface. Several important non-class library functions are provided. A basic linked list class called SequentialList is heavily used. States (see section 9.1) and Portholes (see section 6.2) can have attributes; these are particularly important in code generation. Finally, many of the significant classes in Ptolemy - functional blocks, portholes to implement connections, parameters - are derived from NamedObj, the basic object for implementing a named object that lives in a hierarchy.
