RdfGraphCodec class abstract

Represents a content codec that can be handled by the RDF framework.

A codec plugin encapsulates all the logic needed to work with a specific RDF serialization format (like Turtle, JSON-LD, RDF/XML, etc.). It provides both decoding and encoding capabilities for the format.

To add support for a new RDF format, implement this interface and register an instance with the RdfCodecRegistry.

Example of implementing a new format:

class MyCustomGraphCodec implements RdfGraphCodec {
  @override
  String get primaryMimeType => 'application/x-custom-rdf';

  @override
  Set<String> get supportedMimeTypes => {primaryMimeType};

  @override
  RdfGraphDecoder get decoder => MyCustomGraphDecoder();

  @override
  RdfGraphEncoder get encoder => MyCustomGraphEncoder();

  @override
  bool canParse(String content) {
    // Check if the content appears to be in this format
    return content.contains('CUSTOM-RDF-FORMAT');
  }

  @override
  RdfGraphCodec withOptions({
    RdfGraphEncoderOptions? encoder,
    RdfGraphDecoderOptions? decoder,
  })  => this;
}
