    • Method Detail

      • init

        public void init​(org.apache.solr.common.util.NamedList<?> args)
        Description copied from interface: NamedListInitializedPlugin
        init will be called just once, immediately after creation.

        Source of the initialization arguments will typically be solrconfig.xml, but will ultimately depends on the plugin itself

        Specified by:
        init in interface NamedListInitializedPlugin
        init in class TransformerFactory
        args - non-null list of initialization parameters (may be empty)
      • mayModifyValue

        public boolean mayModifyValue()
        Description copied from interface: TransformerFactory.FieldRenamer
        Returns true if implementations of this class may (even subtly) modify field values. (GeoTransformerFactory may do this, e.g.). To fail safe, the default implementation returns true. This method should be overridden to return false if the implementing class is guaranteed to not modify any values for the fields that it renames.

        mayModifyValue in interface TransformerFactory.FieldRenamer
      • create

        public DocTransformer create​(String display,
                                     org.apache.solr.common.params.SolrParams params,
                                     SolrQueryRequest req,
                                     Map<String,​String> renamedFields,
                                     Set<String> reqFieldNames)
        Description copied from interface: TransformerFactory.FieldRenamer
        Analogous to TransformerFactory.create(String, SolrParams, SolrQueryRequest), but to be implemented by TransformerFactorys that produce DocTransformers that may rename fields.
        Specified by:
        create in interface TransformerFactory.FieldRenamer
        display - The destination field
        params - Local params associated with this transformer (e.g., source field)
        req - The current request
        renamedFields - Maps source=>dest renamed fields. Implementations should check this first, updating their own "source" field(s) as necessary, and if renaming (not copying) fields, should also update this map with the implementations "own" introduced source=>dest field mapping
        reqFieldNames - Set of explicitly requested field names; implementations should consult this set to determine whether it's appropriate to rename (vs. copy) a field (e.g.: boolean copy = reqFieldNames != null && reqFieldNames.contains(sourceField) )
        A transformer to be used in processing field values in returned documents.
