Class UpdateRequestProcessor

java.lang.Object

org.apache.solr.update.processor.UpdateRequestProcessor

Direct Known Subclasses:

DistributedUpdateProcessor, FieldMutatingUpdateProcessor, RegexpBoostProcessor, URLClassifyProcessor

public abstract class UpdateRequestProcessor
extends Object

This is a good place for subclassed update handlers to process the document before it is indexed. You may wish to add/remove fields or check if the requested user is allowed to update the given document... Perhaps you continue adding an error message (without indexing the document)... perhaps you throw an error and halt indexing (remove anything already indexed??) By default, this just passes the request to the next processor in the chain.

solr 1.3
