init

public void init(org.apache.solr.common.util.NamedList<?> args)

Description copied from class: FieldMutatingUpdateProcessorFactory

Will error if any unexpected init args are found, so subclasses should remove any subclass-specific init args before calling this method.

Specified by:

init in interface NamedListInitializedPlugin

Overrides:

init in class FieldMutatingUpdateProcessorFactory

Parameters:

args - non-null list of initialization parameters (may be empty)

getDefaultSelector

public FieldMutatingUpdateProcessor.FieldNameSelector getDefaultSelector(SolrCore core)

Description copied from class: FieldMutatingUpdateProcessorFactory

Defines the default selection behavior when the user has not configured any specific criteria for selecting fields. The Default implementation matches all fields, and should be overridden by subclasses as needed.

Overrides:

getDefaultSelector in class FieldMutatingUpdateProcessorFactory
