Class InternalQuery<T>

java.lang.Object

com.google.gerrit.index.query.InternalQuery<T>

Direct Known Subclasses:

InternalAccountQuery, InternalChangeQuery, InternalGroupQuery

public class InternalQuery<T>
extends Object

Execute a single query over a secondary index, for use by Gerrit internals.

By default, visibility of returned entities is not enforced (unlike in QueryProcessor). The methods in this class are not typically used by user-facing paths, but rather by internal callers that need to process all matching results.

Instances are one-time-use. Other singleton classes should inject a Provider rather than holding on to a single instance.
