  • Constructor Details

    • Http2ClientProtocolConfigImpl

      protected Http2ClientProtocolConfigImpl(Http2ClientProtocolConfig.BuilderBase<?,?> builder)
      Create an instance providing a builder.
      Parameters:
      builder - extending builder base of this prototype

  • Method Details

    • name

      public String name()
      Description copied from interface: NamedService
      Name of this implementation, as provided in ConfiguredProvider.create(Config, String).
      Specified by:
      name in interface Http2ClientProtocolConfig
      Specified by:
      name in interface NamedService
      Returns:
      name of this service

    • priorKnowledge

      public boolean priorKnowledge()
      Description copied from interface: Http2ClientProtocolConfig
      Prior knowledge of HTTP/2 capabilities of the server. If server we are connecting to does not support HTTP/2 and prior knowledge is set to false, only features supported by HTTP/1 will be available and attempts to use HTTP/2 specific will throw an UnsupportedOperationException.

      Plain text connection

      If prior knowledge is set to true, we will not attempt an upgrade of connection and use prior knowledge. If prior knowledge is set to false, we will initiate an HTTP/1 connection and upgrade it to HTTP/2, if supported by the server. plaintext connection (h2c).

      TLS protected connection

      If prior knowledge is set to true, we will negotiate protocol using HTTP/2 only, failing if not supported. if prior knowledge is set to false, we will negotiate protocol using both HTTP/2 and HTTP/1, using the protocol supported by server.
      Specified by:
      priorKnowledge in interface Http2ClientProtocolConfig
      Returns:
      whether to use prior knowledge of HTTP/2

    • maxFrameSize

      public int maxFrameSize()
      Description copied from interface: Http2ClientProtocolConfig
      Configure initial MAX_FRAME_SIZE setting for new HTTP/2 connections. Maximum size of data frames in bytes the client is prepared to accept from the server. Default value is 2^14(16_384).
      Specified by:
      maxFrameSize in interface Http2ClientProtocolConfig
      Returns:
