Package com.norconex.importer.handler.transformer.impl

Class ConstantTransformer

java.lang.Object

com.norconex.importer.handler.transformer.impl.ConstantTransformer

All Implemented Interfaces:

Configurable<ConstantTransformerConfig>, ConfigurableDocHandler<ConstantTransformerConfig>, DocHandler

public class ConstantTransformer
extends Object
implements ConfigurableDocHandler<ConstantTransformerConfig>

Define and add constant values to documents. To add multiple constant values under the same constant name, repeat the constant entry with a different value.

Storing values in an existing field

If a target field with the same name already exists for a document, values will be added to the end of the existing value list. It is possible to change this default behavior with ConstantTransformerConfig.setOnSet(PropertySetter).

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