Class StableSerializerProvider

java.lang.Object

org.apache.clerezza.rdf.stable.serializer.StableSerializerProvider

All Implemented Interfaces:

SerializingProvider

@Service(value=SerializingProvider.class)
public class StableSerializerProvider
extends Object
implements SerializingProvider

A SerializingProvider that tries to provide similar results when serializing graphs. Specifically it tries to label blank nodes deterministically with reasonable complexity. This serializer does not guarantee a deterministic result but it may minimize the amount of modified lines in serialized output.
