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

Class SplitTransformer

java.lang.Object

com.norconex.importer.handler.transformer.impl.SplitTransformer

All Implemented Interfaces:

Configurable<SplitTransformerConfig>, ConfigurableDocHandler<SplitTransformerConfig>, DocHandler

public class SplitTransformer
extends Object
implements ConfigurableDocHandler<SplitTransformerConfig>

Splits an existing metadata value into multiple values based on a given value separator (the separator gets discarded). The "toField" argument is optional (the same field will be used to store the splits if no "toField" is specified"). Duplicates are removed.

Can be used both as a pre-parse (metadata or text content) or post-parse handler.

If no "fieldMatcher" expression is specified, the document content will be used. If the "fieldMatcher" matches more than one field, they will all be split and stored in the same multi-value metadata field.

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 by supplying a PropertySetter.
