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);
}
}
