GeneCoder Plugins

GeneCoder 4.0 provides a plug-in API to customize and/or add functionality to the software. Writing plugins require some knowledge of java programming, and JDK 1.6 or later. Plugins are as simple writing some code, complling into a class file or jar library, and adding the plugin file(s) to the plug-in directory - GeneCoder will automatically load the Plugins on startup.


The plugin API allows three different types of extensions:

  • View Plugins - Customize how sequences are viewed. These plugins are loaded into the main interface and can be selected using the view type selection.
  • Action Plugins - Add functionality to modify, analyze, or create Sequences. These plugins get loaded into the toolbox, and can be run with the click of a button.
  • IO Plugins - Add different File format parsers to read as many file formats as you wish.

The Java API

Writing a Plugin requires a java class to implement the appropriate interface for the appropriate functionality. These interfaces can be found in the com.algosome.genecoder.plugin package (ISequenceViewPlugin, ISequenceActionPlugin, and IIOPlugin). Three libraries are required on the classpath to compile a plugin: Apache log4j, Algosome Commons, and the GeneCoder plugin API.

Plugins are given access to Sequence objects through the SequenceData interface. All sequences in GeneCoder are represented by an implementation of the Sequence interface (it is advised plugins do NOT attempt to implement this interface - rather if one needs to create or read Sequences use the SequenceFactoryBridge or GeneCoderIOBridge classes, respectively). Sequences are wrapped within two parent container objects - a SequenceModel wraps a Sequence and provides basic access to underlying data and method models such as the EditorModel, RestrictionSiteModel (for DNA sequences), SelectionModel, etc...Instances of SequenceModel are in turn wrapped by a SequenceManager, which is responsible for containing a List of sequences and provides access to underlying data and method models (such as a SelectionModel defining which sequences are selected).


The following class file demonstrates a simple ISequenceActionPlugin, the meat of the code is within the doAction method, and has code examples for retrieving a selected sequence from a SequenceData object, as well as examples for how to create a Sequence using the GeneCoderIOBridge and SequenceFactoryBridge classes.
