Interface TitanIndexQuery

All Known Implementing Classes:

IndexQueryBuilder

public interface TitanIndexQuery

A GraphQuery that queries for graph elements directly against a particular indexing backend and hence allows this query mechanism to exploit the full range of features and functionality of the indexing backend. However, the results returned by this query will not be adjusted to the modifications in a transaction. If there are no changes in a transaction, this won't matter. If there are, the results of this query may not be consistent with the transactional state.
