Oliver Becker created LUCENE-6667: ------------------------------------- Summary: Custom attributes get cleared by filters Key: LUCENE-6667 URL: https://issues.apache.org/jira/browse/LUCENE-6667 Project: Lucene - Core Issue Type: Bug Affects Versions: 4.10.4 Reporter: Oliver Becker
I believe the Lucene API enables users to define their custom attributes (by extending {{AttributeImpl}}) which may be added by custom Tokenizers. It seems, the {{clear}} and {{copyTo}} methods must be implemented to clear and restore the state of this custom attribute. However, some filters (in our case the SynonymFilter) simply call {{AttributeSource.clearAttributes}} without invoking {{copyTo}}. Instead the filter just resets some known attributes, simply ignoring all other custom attributes. In the end our custom attribute value is lost. Is this a bug in {{SynonymFilter}} (and others) or are we using the API in the wrong way? A solution might be of course to provide empty implementations of {{clear}} and {{copyTo}}, but I'm not sure if this has other unwanted effects. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
