## Class NDJSONLDParser

- java.lang.Object
- - org.eclipse.rdf4j.rio.helpers.AbstractRDFParser
  - - org.eclipse.rdf4j.rio.jsonld.JSONLDParser

- All Implemented Interfaces:
    `RDFParser`

      public class NDJSONLDParser
      extends JSONLDParser
      implements RDFParser

  Introduce a parser capable of parsing Newline Delimited JSON-LD, where each line is a serialized JSON-LD record. The format is inspired by Newline Delimited JSON formathttp://ndjson.org/. Even though each line is a separate JSON-LD document, the whole document is treated as a single RDF document, having one single BNodes context to preserve BNodes identifiers.

    - #### NDJSONLDParser

          public NDJSONLDParser​(ValueFactory valueFactory)

      Creates a RDF4J NDJSONLD Parser using the given `ValueFactory` to create new `Value`s.
      Parameters:
        `valueFactory` - The ValueFactory to use

  - ### Method Detail

    - #### getRDFFormat

          public RDFFormat getRDFFormat()

      Description copied from interface: `RDFParser`
      Gets the RDF format that this parser can parse.
      Specified by:
        `getRDFFormat` in interface `RDFParser`
      Overrides:
        `getRDFFormat` in class `JSONLDParser`

    - #### getJSONObject

          protected Object getJSONObject​(InputStream in,
                                         Reader reader,
                                         com.fasterxml.jackson.core.JsonFactory factory)
                                  throws IOException

      Overrides:
        `getJSONObject` in class `JSONLDParser`
      Throws:
        `IOException`

    - #### parse

          public void parse​(InputStream in,
                            String baseURI)
                     throws RDFParseException,
                            RDFHandlerException,
                            IOException

      Description copied from interface: `RDFParser`
      Parses the data from the supplied InputStream, using the supplied baseURI to resolve any relative URI references.
      Specified by:
        `parse` in interface `RDFParser`
      Overrides:
        `parse` in class `JSONLDParser`
      Parameters:
        `in` - The InputStream from which to read the data.
        `baseURI` - The URI associated with the data in the InputStream. May be `null`. Parsers for syntax formats that do not support relative URIs will ignore this argument.

        Note that if the data contains an embedded base URI, that embedded base URI will overrule the value supplied here (see RFC 3986 section 5.1 for details).

      Throws:
        `RDFParseException` - If the parser has found an unrecoverable parse error.
        `RDFHandlerException` - If the configured statement handler has encountered an unrecoverable error.
        `IOException` - If an I/O error occurred while data was read from the InputStream.
