- to create a plugin, you will create (at least) two files, the MANIFEST.MF file and the Activator
- we sill will create a bundle that adds a new graph function
- create the following MANIFEST.MF file:
| Panel |
|---|
Manifest-Version: 1.0 |
- (note - there are spaces at the beginning of the extension lines, and a blank line at the end)
- Now, create the Activator,
mypackage.MyActivator.java
| Code Block | ||||
|---|---|---|---|---|
| ||||
package mypackage;
import java.util.Properties;
import org.osgi.framework.BundleActivator;
import org.osgi.framework.BundleContext;
import org.osgi.framework.ServiceRegistration;
import com.affymetrix.genometryImpl.util.FloatTransformer;
public class MyActivator implements BundleActivator {
private BundleContext bundleContext;
private ServiceRegistration serviceRegistration;
protected BundleContext getContext() {
return bundleContext;
}
public void start(BundleContext _bundleContext) throws Exception {
bundleContext = _bundleContext;
serviceRegistration = bundleContext.registerService(FloatTransformer.class.getName(), new InverseTransformer(), new Properties());
}
public void stop(BundleContext _bundleContext) throws Exception {
if (serviceRegistration != null) {
serviceRegistration.unregister();
}
bundleContext = null;
}
}
|
- And create the Transformer,
mypackage.MyTransformer.java
| Code Block | ||||
|---|---|---|---|---|
| ||||
package mypackage;
import com.affymetrix.genometryImpl.util.FloatTransformer;
public class MyTransformer implements FloatTransformer {
final String paramPrompt;
final String name;
public MyTransformer() {
super();
paramPrompt = null;
name = "MyTransformer";
}
public String getParamPrompt() { return null; }
public String getName() {
return name;
}
public String getDisplay() {
return name;
}
public float transform(float x) {
return x; // boring, put your own math function here, return 1.0/x; or return 3*x*x*x - 2*x*x +8*x - 6;
}
public float inverseTransform(float x) {
return 0.0f;
}
public boolean isInvertible() { return false; }
public boolean setParameter(String s) {
return true;
}
}
