Command Layer Definition
Command layer contains mechanism to make Cytoscape functions easily accessible from application layer. This layer should be separated from application layer and can be used in any mode: Desktop application, server version, and command line version.
Requirments
- Command layer should be separated from application or UI.
- Commands should be accessible from scripting (dynamic) languages.
- Should be manageable by Undo manager (in application layer).
- Extensible. Plugin writers and developers use Cytoscape as library can add their own commands.
Multiple Language Support
Commands should be easily accessible dynamic (scripting) languages, including Python, Ruby, and JavaScript.
Functions Encapcelated as Command
In general, most of the classes in cytoscape.actions will be converted into Commands.
Design
