### Dumper

    public Dumper()

Method Detail

### configure

    public void configure(DBBroker broker,
                          Collection parent,
                          java.util.Map parameters)
                   throws CollectionConfigurationException

  Description copied from class: `FilteringTrigger`
  Configure the trigger. The default implementation just stores the parent collection reference into the field `collection`. Use method `getCollection` to later retrieve the collection.

  Specified by:
    `configure` in interface `Trigger`
  Overrides:
    `configure` in class `FilteringTrigger`
  Throws:
    `CollectionConfigurationException`

### prepare

    public void prepare(int event,
                        DBBroker broker,
                        Txn transaction,
                        XmldbURI documentName,
                        DocumentImpl existingDocument)
                 throws TriggerException

  Description copied from interface: `DocumentTrigger`
  This method is called once before the database will actually parse the input data. You may take any action here, using the supplied broker instance.

  Parameters:
    `event` - the type of event that triggered this call (see the constants defined in this interface). The ContentHandler instance for the output.
    `broker` - the database instance used to process the current action.
    `transaction` - the current transaction context
    `documentName` - the full absolute path of the document currently processed.
    `existingDocument` - optional: if event is a `Trigger.UPDATE_DOCUMENT_EVENT`, existingDocument will contain the Document object for the old document, which will be overwritten. Otherwise, the parameter is null.
  Throws:
    `TriggerException` - throwing a TriggerException will abort the current action.

### finish

    public void finish(int event,
                       DBBroker broker,
                       Txn transaction,
                       DocumentImpl document)

  Description copied from interface: `DocumentTrigger`
  This method is called after the operation completed. At this point, the document has already been stored.

  Specified by:
    `finish` in interface `DocumentTrigger`
  Overrides:
    `finish` in class `FilteringTrigger`
