NQuadsEncoder class final
Encoder for the N-Quads format.
This class extends the RdfGraphEncoder abstract class to convert RDF graphs into the N-Quads serialization format. N-Quads is a line-based format where each line represents a single triple, making it very simple to parse and generate.
The encoder creates one line for each triple in the form:
<subject> <predicate> <object> .
N-Quads is fully compatible with the RDF 1.1 N-Quads specification (https://www.w3.org/TR/n-quads/).

Methods
-
bind(
Stream< RdfDataset> stream) → Stream<String> -
Transforms the provided
stream.inherited -
cast<
RS, RT> () → Converter< RS, RT> -
Provides a
Converter<RS, RT>view of this stream transformer.inherited -
convert(
RdfDataset dataset, {String? baseUri}) → String - Encodes an RDF dataset to a string representation in a specific format.
-
encode(
RdfDataset dataset, {Map< BlankNodeTerm, String> ? blankNodeLabels, bool generateNewBlankNodeLabels = true}) → String -
If the
generateNewBlankNodeLabelsflag is false andblankNodeLabelsis not provided, or does not contain all blank nodes in the dataset, an exception is thrown to indicate inconsistent blank node labeling. -
fuse<
TT> (Converter< String, TT> other) → Converter<RdfDataset, TT> -
Fuses
thiswithother.inherited -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
startChunkedConversion(
Sink< String> sink) → Sink<RdfDataset> -
Starts a chunked conversion.
inherited
-
toString(
) → String -
A string representation of this object.
inherited
-
withOptions(
RdfGraphEncoderOptions options) → RdfDatasetEncoder - Creates a new encoder instance with the specified options.
Operators
-
operator ==(
Object other) → bool -
The equality operator.
