Components details are not getting logged in my database when unpublishing the page using Tridion Deployer extension - tridion

Question

I am trying to add the unpublished components entry in my custom storage extension. We know that we don't have any base class in Tridion for ComponentUndeploy as we have for deploy "ComponentDeploy", so I am trying to use ComponentPresentationUndeploy class to track the components which are getting and below is sample code how I am trying to track.
package com.tridion.custom.extensions;
import com.tridion.broker.StorageException;

}

public void process(TransportPackage paramTransportPackage) throws ProcessingException
{

try
{
Iterator localIterator = localProcessorInstructions.getArguments();
while (localIterator.hasNext())
{
Object localObject = localIterator.next();
if (localObject instanceof ComponentPresentationKey)
{
ComponentPresentationKey localComponentPresentationKey = (ComponentPresentationKey) localObject;
long[] arrayOfLong = new long[2];
arrayOfLong[0] = localComponentPresentationKey.getComponentKey().getId().getItemId();
arrayOfLong[1] = localComponentPresentationKey.getTemplateKey().getId().getItemId();
int PubID = localComponentPresentationKey.getComponentKey().getId().getPublicationId();
String tcmID = Integer.toString(localComponentPresentationKey.getComponentKey().getId().getItemId());
log.info("SearchComponentUndeployer -PubID" + PubID);
log.info("SearchComponentUndeployer -tcmID" + tcmID);

log.info("SearchComponentUndeployer -itemDAO"+ itemDAO.getStorageId());
ComponentMeta compObject = (ComponentMeta) MapperFactory.mapItemMetaInstance(itemDAO.findByPrimaryKey(PubID, localComponentPresentationKey.getComponentKey().getId().getItemId(),ItemTypeSelector.COMPONENT));
log.info("SearchComponentUndeployer -compObject"+ compObject.getTitle());
String formatTCMID = String.format("tcm:%d-%s-64", PubID,tcmID);
log.info("SearchComponentUndeployer - formatTCMID -"+ formatTCMID);
String strIgnorePubIds = "232,481";
String strPubId = Integer.toString(PubID);
Date lastPublishedDate = compObject.getLastPublishDate();
String schemaID = Integer.toString(compObject.getSchemaId());
if (!strIgnorePubIds.contains(strPubId))
{
PublishAction publishAction = new PublishAction();
publishAction.setAction("DEL");
publishAction.setTcmUri(formatTCMID);
publishAction.setItemType(16);
publishAction.setPublicationID(PubID);
publishAction.setLastPublishedDate(lastPublishedDate);
publishAction.setSchemaID(schemaID);
PublishActionDAO publishActionDAO = (PublishActionDAO) StorageManagerFactory.getDefaultDAO("PublishAction");
log.debug("SearchComponentUndeployer Going to Store bean -" + publishAction.toString());
publishAction = publishActionDAO.store(publishAction);
log.debug("SearchComponentUndeployer Stored bean -" + publishAction);
}
DeploymentHandler.undeploy(new TCDURI(PubID, 73014444080L, arrayOfLong));
}
}
}
catch (StorageException e)
{
log.error("Could not undeploy component presentation", e);
}
}
}
Any idea why I am not getting any entry for components in my database
Edit: Added sample code from PageUndeploy implementation done by me:
Object argument = iterator.next();
if (argument instanceof PageKey)
{
PageKey pageKey = (PageKey) argument;
TCDURI pageMetaURI = new TCDURI(pageKey.getId() .getPublicationId(), 1168231104576L, pageKey.getId().getItemId());
PageMeta pageMeta = this.pageMetaHome.findByPrimaryKey(pageMetaURI.getPublicationId(),(int) pageMetaURI.getItemId());
if (pageMeta == null)
{
DeploymentHandler.undeploy(pageMetaURI);
}
else
{
//Here I need to loop for componentpresentation and get component object
}
}

You can try this as I just taken class name from your input
List<ComponentPresentationMeta> lstCompObjects= pageMeta.getComponentPresentationMetas();
if(lstCompObjects != null && !lstCompObjects.isEmpty())
{
for(ComponentPresentationMeta compMeta : lstCompObjects)
{
String compID = Integer.toString(compMeta.getComponentId());
ItemDAO itemDAO = ((ItemDAO) StorageManagerFactory.getDAO(compMeta.getPublicationId(), StorageTypeMapping.COMPONENT_META));
ComponentMeta compObject = (ComponentMeta) MapperFactory.mapItemMetaInstance(itemDAO.findByPrimaryKey(compMeta.getPublicationId(), compMeta.getComponentId(),ItemTypeSelector.COMPONENT));
PublishAction compPublishAction = new PublishAction();
compPublishAction.setAction("DEL");
compPublishAction.setTcmUri(compID);
compPublishAction.setItemType(16);
compPublishAction.setPublicationID(compMeta.getPublicationId());
compPublishAction.setLastPublishedDate(compObject.getLastPublicationDate());
compPublishAction.setSchemaID(Integer.toString(compObject.getSchemaId()));
compPublishAction = publishActionDAO.store(compPublishAction);
}
}
