      public static XMPMeta parse (InputStream in) throws XMPException
      Parsing with default options.
      Parameters:
      in - an InputStream

    • parse

      public static XMPMeta parse (InputStream in, ParseOptions options) throws XMPException
      These functions support parsing serialized RDF into an XMP object, and serailizing an XMP object into RDF. The input for parsing may be any valid Unicode encoding. ISO Latin-1 is also recognized, but its use is strongly discouraged. Serialization is always as UTF-8.
      parseFromBuffer() parses RDF from an InputStream. The encoding is recognized automatically.
      Parameters:
      in - an InputStream
      options - Options controlling the parsing.
      The available options are:
      • XMP_REQUIRE_XMPMETA - The XML element is required around .
      • XMP_STRICT_ALIASING - Do not reconcile alias differences, throw an exception.
      Note:The XMP_STRICT_ALIASING option is not yet implemented.
      Returns:
      Returns the XMPMeta-object created from the input.
      Throws:
      XMPException - If the file is not well-formed XML or if the parsing fails.
    • parseFromString

      public static XMPMeta parseFromString (String packet) throws XMPException
      Parsing with default options.
      Parameters:
      packet - a String contain an XMP-file.
      Returns:
      Returns the XMPMeta-object created from the input.
      Throws:
      XMPException - If the file is not well-formed XML or if the parsing fails.

      Parameters:
      packet - a String contain an XMP-file.
      options - Options controlling the parsing.
      Returns:
      Returns the XMPMeta-object created from the input.
      Throws:
      XMPException - If the file is not well-formed XML or if the parsing fails.

    • serialize

      public static void serialize (XMPMeta xmp, OutputStream out) throws XMPException
      Serializes an XMPMeta-object as RDF into an OutputStream with default options.
      Parameters:
      xmp - a metadata object
      out - an OutputStream to write the serialized RDF to.
      Throws:

    • serialize

      public static void serialize (XMPMeta xmp, OutputStream out, SerializeOptions options) throws XMPException
      Serializes an XMPMeta-object as RDF into an OutputStream.
      Parameters:

      options - Options to control the serialization (see SerializeOptions).
      Returns:
      Returns a string containing the serialized RDF.
