Method Detail

getSchema

public Schema<ChangeData> getSchema()

Specified by:

getSchema in interface ChangeIndex

Returns:

the schema version used by this index.

close

public void close()

Description copied from interface: ChangeIndex

Close this index.

Specified by:

close in interface ChangeIndex

replace

public void replace(ChangeData cd)
             throws java.io.IOException

Description copied from interface: ChangeIndex

Update a change document in the index.

Semantically equivalent to deleting the document and reinserting it with new field values. A document that does not already exist is created. Results may not be immediately visible to searchers, but should be visible within a reasonable amount of time.

Specified by:

replace in interface ChangeIndex

Parameters:

cd - change document

Throws:

java.io.IOException

delete

public void delete(com.google.gerrit.reviewdb.client.Change.Id id)
            throws java.io.IOException

Description copied from interface: ChangeIndex

Delete a change document from the index by id.

Specified by:

delete in interface ChangeIndex

Parameters:

id - change id

Throws:

java.io.IOException

deleteAll

public void deleteAll()
               throws java.io.IOException

Description copied from interface: ChangeIndex

Delete all change documents from the index.

Specified by:

deleteAll in interface ChangeIndex

Throws:

java.io.IOException

getSource

public ChangeDataSource getSource(Predicate<ChangeData> p,
                                  int start,
                                  int limit)
                           throws com.google.gerrit.server.query.QueryParseException

Description copied from interface: ChangeIndex

Convert the given operator predicate into a source searching the index and returning only the documents matching that predicate.

This method may be called multiple times for variations on the same predicate or multiple predicate subtrees in the course of processing a single query, so it should not have any side effects (e.g. starting a search in the background).

Specified by:

getSource in interface ChangeIndex

Parameters:

p - the predicate to match. Must be a tree containing only AND, OR, or NOT predicates as internal nodes, and IndexPredicates as leaves.

start - offset in results list at which to start returning results.

limit - maximum number of results to return.

Returns:

a source of documents matching the predicate. Documents must be returned in descending updated timestamp order.

Throws:

com.google.gerrit.server.query.QueryParseException - if the predicate could not be converted to an indexed data source.

markReady

public void markReady(boolean ready)
               throws java.io.IOException

Description copied from interface: ChangeIndex

Mark whether this index is up-to-date and ready to serve reads.

Specified by:

markReady in interface ChangeIndex

Parameters:

ready - whether the index is ready

Throws:

java.io.IOException

getMaxLimit

public int getMaxLimit()
