public class FastHashedTripleBunch
extends FastHashSet<Triple>
implements FastTripleBunch

Hashed implementation of FastTripleBunch built on top of FastHashSet. Used by FastTripleStore once a bunch grows past the size threshold at which a linear-scan FastArrayBunch stops being faster.

Constructor Details

FastHashedTripleBunch

public FastHashedTripleBunch(JenaSet<Triple> set)

Create a new hashed bunch pre-populated from the given set of triples. The initial capacity is chosen at 1.5x the source size, so the new bunch fits the existing triples and has some headroom for growth before it needs to rehash.

Parameters:

set - the source set of triples (typically the array bunch being promoted)

FastHashedTripleBunch

public FastHashedTripleBunch()

Creates an empty hashed bunch with the default initial capacity.

Method Details

isArray

public boolean isArray()

Description copied from interface: FastTripleBunch

Answer true iff this bunch is backed by a flat array (i.e. is a FastArrayBunch). Exposed as an explicit method so callers can avoid instanceof checks on this hot path.

Specified by:

isArray in interface FastTripleBunch

Returns:

true if this bunch is array-backed

copy

public FastHashedTripleBunch copy()

Specified by:

copy in interface org.apache.jena.atlas.lib.Copyable<FastTripleBunch>
