Description

Class Summary

LoadLegacyLetterStreams	Create letter streams.
LoadLetterStreams	Create letter streams.
LoadParticleStreams	Create particles streams. Definition of colors is still not developed properly.
LoadPolygonStreams	Create letter streams.
RulePredicate	Simple data class for a rule that is a predicate with 4 inputs. How should this be represented in a text file? A: POINT_COUNT == 5 A POINT_COUNT == 5 A POINT_COUNT == 5; A: POINT_COUNT == 5; LINE_COUNT = 5 ! A POINT_COUNT == 5; LINE_COUNT = 5 A POINT_COUNT == 5; LINE_COUNT = 5 def A POINT_COUNT == 5; LINE_COUNT = 5 ========== def A POINT_COUNT == 5 LINE_COUNT == 5 HOLE_COUNT == 1 ===== def A POINT_COUNT == 5 && LINE_COUNT == 5 || HOLE_COUNT == 1
StreamNames	Class with definitions common stream names. First strategy was not to used the same headlines and stream names to make it easier to debug in case of an error. This has been dropped in order to make it simpler for the users.

Package org.shapelogic.streamlogic Description

streamlogic

New library for functional programming style lazy calculation.

This is going to replace the system up to ShapeLogic 0.8 what was mainly based on goal driven tasks. Somewhat like the language Prolog but without backtracking or unification.
The same rules that before was creating tasks are now creating derivative streams.

Dependency

• This package can depend on util, calculation.
• There is no dependency of any image processing code or any external libraries outside Java 6.
• This can be used in a Java application, just by adding shapelogic_.jar.

Declarative programming

Declarative programming in ShapeLogic is build on the following:

• Rule database that can access Java object using Scripting languages or JEXL
• Streams / lazy lists
• Lazy calculations
• Inversion of Control, IoC, for creating the right object implementing an interface
