JSci Specification

This is here as a reminder for me and an aid to you when developing further classes for JSci.

Naming

All sub-package names should be in lower case.

Hierarchy

Any class with the postfix Math should extend JSci.maths.AbstractMath, be declared public final and be impossible to instantiate.

Class Design

Classes that encapsulate mathematical objects should follow these guidelines:

• implement a sub-interface of JSci.maths.Member.
• generally be immutable (does not implement java.lang.Cloneable interface). This ensures these objects are thread-safe.
• contain methods that perform defined mathematical operations on the class. The following method names should be used where appropriate:
  • add()
  • subtract()
  • multiply()
  • divide()
  • dimension()
• non-mathematical methods should be kept to an absolute minimum - put them in another class. This is to keep the dependence on other (auxiliary) classes to a minimum.
