public final class TruncateFieldUpdateProcessorFactory
extends FieldMutatingUpdateProcessorFactory

Truncates any CharSequence values found in fields matching the specified conditions to a maximum character length.

By default this processor matches no fields

For example, with the configuration listed below any documents containing a String in any field declared in the schema using StrField will be truncated to no more then 100 characters

 <processor class="solr.TruncateFieldUpdateProcessorFactory">
   <str name="typeClass">solr.StrField</str>
   <int name="maxLength">100</int>
 </processor>

Method Detail

init

public void init(NamedList args)

Description copied from class: FieldMutatingUpdateProcessorFactory

Handles common initialization related to source fields for constructing the FieldNameSelector to be used. 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

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
