Class SliceQuery

java.lang.Object

com.thinkaurelius.titan.graphdb.query.BaseQuery

com.thinkaurelius.titan.diskstorage.keycolumnvalue.SliceQuery

All Implemented Interfaces:

BackendQuery<SliceQuery>, Query

Direct Known Subclasses:

KeyRangeQuery, KeySliceQuery

public class SliceQuery
extends BaseQuery
implements BackendQuery<SliceQuery>

Queries for a slice of data identified by a start point (inclusive) and end point (exclusive). Returns all StaticBuffers that lie in this range up to the given limit.

If a SliceQuery is marked static it is expected that the result set does not change.
