    • request

      public static RestRequest request​(org.elasticsearch.common.xcontent.NamedXContentRegistry xContentRegistry, HttpRequest httpRequest, HttpChannel httpChannel)
      Creates a new REST request. This method will throw RestRequest.BadParameterException if the path cannot be decoded
      Parameters:
      xContentRegistry - the content registry
      httpRequest - the http request
      httpChannel - the http channel
      Throws:
      RestRequest.BadParameterException - if the parameters can not be decoded
      RestRequest.ContentTypeHeaderException - if the Content-Type header can not be parsed

    • requestWithoutParameters

      public static RestRequest requestWithoutParameters​(org.elasticsearch.common.xcontent.NamedXContentRegistry xContentRegistry, HttpRequest httpRequest, HttpChannel httpChannel)
      Creates a new REST request. The path is not decoded so this constructor will not throw a RestRequest.BadParameterException.
      Parameters:
      xContentRegistry - the content registry
      httpRequest - the http request
      httpChannel - the http channel
      Throws:
      RestRequest.ContentTypeHeaderException - if the Content-Type header can not be parsed

    • contentParser

      public final org.elasticsearch.common.xcontent.XContentParser contentParser() throws IOException
      A parser for the contents of this request if there is a body, otherwise throws an ElasticsearchParseException. Use applyContentParser(CheckedConsumer) if you want to gracefully handle when the request doesn't have any contents. Use contentOrSourceParamParser() for requests that support specifying the request body in the source param.
      Throws:
      IOException

    • applyContentParser

      public final void applyContentParser​(org.elasticsearch.core.CheckedConsumer<org.elasticsearch.common.xcontent.XContentParser,​IOException> applyParser) throws IOException
      If there is any content then call applyParser with the parser, otherwise do nothing.
      Throws:
      IOException

    • hasContentOrSourceParam

      public final boolean hasContentOrSourceParam()
      Does this request have content or a source parameter? Use this instead of hasContent() if this RestHandler treats the source parameter like the body content.

    • contentOrSourceParamParser

      public final org.elasticsearch.common.xcontent.XContentParser contentOrSourceParamParser() throws IOException
      A parser for the contents of this request if it has contents, otherwise a parser for the source parameter if there is one, otherwise throws an ElasticsearchParseException. Use withContentOrSourceParamParserOrNull(CheckedConsumer) instead if you need to handle the absence request content gracefully.
      Throws:
      IOException

    • withContentOrSourceParamParserOrNull

      public final void withContentOrSourceParamParserOrNull​(org.elasticsearch.core.CheckedConsumer<org.elasticsearch.common.xcontent.XContentParser,​IOException> withParser) throws IOException
      Call a consumer with the parser for the contents of this request if it has contents, otherwise with a parser for the source parameter if there is one, otherwise with null. Use contentOrSourceParamParser() if you should throw an exception back to the user when there isn't request content.
      Throws:
      IOException

    • contentOrSourceParam

      public final org.elasticsearch.core.Tuple<org.elasticsearch.common.xcontent.XContentType,​BytesReference> contentOrSourceParam()
      Get the content of the request or the contents of the source param or throw an exception if both are missing. Prefer contentOrSourceParamParser() or withContentOrSourceParamParserOrNull(CheckedConsumer) if you need a parser.

    • parseContentType

      public static org.elasticsearch.common.xcontent.XContentType parseContentType​(List<String> header)
      Parses the given content type string for the media type. This method currently ignores parameters.
