...

To create a new Artifact you can use the following code. Here registry refers to valid org.wso2.carbon.registry.core.Registry object and projectKey refers to shortName in the Registry extension file.

Code Block


import org.wso2.carbon.governance.api.generic.GenericArtifactManager;
   
import org.wso2.carbon.governance.api.generic.dataobjects.GenericArtifact;

GovernanceUtils.loadGovernanceArtifacts((UserRegistry) registry);
  GenericArtifactManager artifactManager = new GenericArtifactManager(registry, projectKey);

   GenericArtifact artifact  = artifactManager.newGovernanceArtifact(new QName("http://www.example.com","event"));
  
 artifactManager.addGenericArtifact(artifact);

...

To make further changes to a Artifact which already in the Registry you can use the updateGenericArtifact() method.

Code Block
artifact.addAttribute("EventName","Running"); artifactManager.updateGenericArtifact(artifact);

...

To remove an Artifact you should have the reference to that Artifact, which can be retrieve using artifact.getId(). Then you can use the removeGenericArtifact() method to remove the Artifact.

Code Block
String artifactId = artifact.getId(); artifactManager.removeGenericArtifact(artifactId);

...

To retrieve an Artifact you can use the getGenericArtifact() method.

Code Block
GenericArtifact artifact = artifactManager.getGenericArtifact(artifactId);

...

Key - EventName.
Value - Running.

Code Block


GenericArtifact[] artifacts = artifactManager.findGenericArtifacts(
    new GenericArtifactFilter() {
        public boolean matches(GenericArtifact genericArtifact) throws GovernanceException {
            String attributeVal = artifact.getAttribute("EventName");
if(attributeVal != null && attributeVal == "Running"){      return (attributeVal != null        return true&& attributeVal.equals("Running"));
           }
} return false; } });

Associate a Lifecycle to the Artifact

To associate a Lifecycle to the Artifact you can use the attachLifecycle() method.

Code Block
artifact.attachLifecycle("LifeCycleName"); artifactManager.updateGenericArtifact(artifact);

...

To get the dependents and dependencies of an Artifact you can use the getDependents() and getDependencies() methods.

Code Block
GovernanceArtifact[] dependents = artifact.getDependents(); GovernanceArtifact[] dependencies = artifact.getDependencies();
