Interface DeletionQuery

All Known Implementing Classes:

SingularTermDeletionQuery

public interface DeletionQuery

interface for Serializable Queries that can be used to delete from an index. These have to be passed safely between VMs (we cannot rely on Lucene's queries here because of that).

Method Summary

Modifier and Type	Method and Description
int	getQueryKey() used to identify the type of query faster (no need for instanceof checks)
String[]	serialize() We are serializing to a String array here instead of a byte array since we don't want implementors to use the standard Java Serialization API by mistake
Query	toLuceneQuery(ScopedAnalyzer analyzerForEntity) converts this DeletionQuery to a Lucene Query

Method Detail

getQueryKey

int getQueryKey()

used to identify the type of query faster (no need for instanceof checks)

Returns:

the unique query key

toLuceneQuery

Query toLuceneQuery(ScopedAnalyzer analyzerForEntity)

converts this DeletionQuery to a Lucene Query

Parameters:

analyzerForEntity - the analyzer to be used for this query

Returns:

the deletion query as Lucene Query

serialize

String[] serialize()

We are serializing to a String array here instead of a byte array since we don't want implementors to use the standard Java Serialization API by mistake

Returns:

a String[] representation of this DeletionQuery
