ProtoEncoder

eu.ostrzyciel.jelly.core.ProtoEncoder

abstract class ProtoEncoder[TNode, TTriple, TQuad, TQuoted](val options: RdfStreamOptions)

Stateful encoder of a protobuf RDF stream.

This class supports all stream types and options, but usually does not check if the user is conforming to them. It will, for example, allow the user to send generalized triples in a stream that should not have them. Take care to ensure the correctness of the transmitted data, or use the specialized wrappers from the stream package.

Abstract methods

Turn an RDF graph node into its protobuf representation.

Use the protected final inline make*Graph methods in this class to create the nodes.

Attributes

node: RDF graph node
Returns:: RdfTerm
Throws:: RdfProtoSerializationError
if node cannot be encoded

Turn an RDF node (S, P, or O) into its protobuf representation.

Use the protected final inline make* methods in this class to create the nodes.

Attributes

node: RDF node
Returns:: RdfTerm
Throws:: RdfProtoSerializationError
if node cannot be encoded

Concrete methods

Add an RDF quad statement to the stream.

Attributes

quad: quad to add
Returns:: iterable of stream rows

Add an RDF triple statement to the stream.

Attributes

triple: triple to add
Returns:: iterable of stream rows

Signal the end of a delimited graph in a GRAPHS stream.

Attributes

Returns:: iterable of stream rows (always of length 1)

Signal the start of the default delimited graph in a GRAPHS stream.

Attributes

Returns:: iterable of stream rows
