ArtifactListeners

ArtifactListeners allow you to attach logic that runs each time a file is expanded.

artifactListeners.xml

Add a DataResource file to your expansion-resource:

<dataResource type="expansionControl::ArtifactListener">
  <artifactListener name="MyListener">
    <attachTo name="before-write"/> <!-- before-write or after-write -->
    <implementation>net.demo.MyListener</implementation>
    <!-- Next are some optional attributes to filter when to run the listener -->
    <layerType name="LOGIC_LAYER"/> <!-- optional, filters logic layer artifacts -->
    <technology name="EJB3"/> <!-- optional, filters Ejb3 artifacts -->
    <fileExtensions>java, kt</fileExtensions> <!-- optional, filters .java or .kt files -->
  </artifactListener>
</dataResource>

MyListener.java

Provide a java class that implements the ArtifactListener interface:

import net.democritus.elements.ArtifactComposite;
import net.democritus.expander.listeners.ArtifactListener;
import net.democritus.expander.listeners.ArtifactWriteParameters;

public class MyListener implements ArtifactListener {

  @Override
  public void perform(ArtifactWriteParameters parameters) {
    CompositeExpansionContext<?> expansionContext = parameters.getExpansionContext();
    ArtifactComposite artifact = parameters.getArtifact();
    Path artifactFile = parameters.getArtifactFile();
    // Do something with the information available.
  }

}
