Class KeepOnlyTransformerConfig

java.lang.Object

com.norconex.importer.handler.BaseLabelableConfig

com.norconex.importer.handler.BaseDocHandlerConfig

com.norconex.importer.handler.transformer.impl.KeepOnlyTransformerConfig

All Implemented Interfaces:

Labelable

public class KeepOnlyTransformerConfig
extends BaseDocHandlerConfig

Keep only the metadata fields provided, delete all other ones. Exact field names (case-insensitive) to keep can be provided as well as a regular expression that matches one or many fields (since 2.1.0).

Note: Unless you have good reasons for doing otherwise, it is recommended to use this handler as one of the last ones to be executed. This is a good practice to ensure all metadata fields are available to other handlers that may require them even if they are not otherwise required.

Can be used both as a pre-parse or post-parse handler.
