public DummyChangeIndex()

Method Detail

getSchema

public Schema<ChangeData> getSchema()

Specified by:

getSchema in interface Index<com.google.gerrit.reviewdb.client.Change.Id,ChangeData>

Returns:

the schema version used by this index.

close

public void close()

Description copied from interface: Index

Close this index.

Specified by:

close in interface Index<com.google.gerrit.reviewdb.client.Change.Id,ChangeData>

replace

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

Description copied from interface: Index

Update a 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 Index<com.google.gerrit.reviewdb.client.Change.Id,ChangeData>

Parameters:

cd - document object

Throws:

java.io.IOException

delete

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

Description copied from interface: Index

Delete a document from the index by key.

Specified by:

delete in interface Index<com.google.gerrit.reviewdb.client.Change.Id,ChangeData>

Parameters:

id - document key

Throws:

java.io.IOException

deleteAll

public void deleteAll()
               throws java.io.IOException

Description copied from interface: Index

Delete all documents from the index.

Specified by:

deleteAll in interface Index<com.google.gerrit.reviewdb.client.Change.Id,ChangeData>

Throws:

java.io.IOException

getSource

public ChangeDataSource getSource(Predicate<ChangeData> p,
                                  QueryOptions opts)

Description copied from interface: Index

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 Index<com.google.gerrit.reviewdb.client.Change.Id,ChangeData>

Parameters:

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

opts - query options not implied by the predicate, such as start and limit.

Returns:

a source of documents matching the predicate, returned in a defined order depending on the type of documents.

markReady

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

Description copied from interface: Index

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

Specified by:

markReady in interface Index<com.google.gerrit.reviewdb.client.Change.Id,ChangeData>

Parameters:

ready - whether the index is ready

Throws:

java.io.IOException

getMaxLimit

public int getMaxLimit()

stop

public void stop()

Description copied from interface: Index

Stop and await termination of all executor threads

Specified by:

stop in interface Index<com.google.gerrit.reviewdb.client.Change.Id,ChangeData>
