      public Optional<Schema> getSchemaOptional()

    • getSchema

      @Deprecated public Schema getSchema()
      Deprecated.
      Deprecated. Use getSchemaOptional() instead.
      Returns the schema, or an empty schema if no schema is present.

      public long getBytes()

    • getRecords

      public long getRecords()

    • getDescriptor

      public FlightDescriptor getDescriptor()

    • getEndpoints

      public List<FlightEndpoint> getEndpoints()

    • getOrdered

      public boolean getOrdered()

    • getAppMetadata

      public byte[] getAppMetadata()

    • serialize

      public ByteBuffer serialize()
      Get the serialized form of this protocol message.

      Intended to help interoperability by allowing non-Flight services to still return Flight types.

    • deserialize

      public static FlightInfo deserialize(ByteBuffer serialized) throws IOException, URISyntaxException
      Parse the serialized form of this protocol message.

      Intended to help interoperability by allowing Flight clients to obtain stream info from non-Flight services.

      Parameters:
      serialized - The serialized form of the FlightInfo, as returned by serialize().
      Returns:
      The deserialized FlightInfo.
      Throws:
      IOException - if the serialized form is invalid.
      URISyntaxException - if the serialized form contains an unsupported URI format.
