Prerequisites
IDE: Eclipse Java EE IDE for Web Developers. Version: 3.7+
Step by Step
Let's start creating a project using the eclipse IDE that is mavenized. After having mavenized the project in eclipse you have to put dependencies.
Step by Step
The maven artifact coordinates are:
<dependency> <groupId>org.gcube.dataanalysis</groupId> <artifactId>ecological-engine</artifactId> <version>1.6.1-SNAPSHOT</version> </dependency>
Let's start creating a new call which implements basic algorithm; it will be executed by Statistical Manager.
Next step is to extend basic interface StandardLocalExternalAlgorithm.
The following snippet shows unimplemented interface methods that we are going to fulfill.
public class SimpleAlgorithm extends StandardLocalExternalAlgorithm{ @Override public void init() throws Exception { // TODO Auto-generated method stub } @Override public String getDescription() { // TODO Auto-generated method stub return null; } @Override protected void process() throws Exception { // TODO Auto-generated method stub } @Override protected void setInputParameters() { // TODO Auto-generated method stub } @Override public void shutdown() { // TODO Auto-generated method stub } @Override public StatisticalType getOutput() { return null; } }
