      Modifier and Type Method Description
      java.lang.Class<T> getMessageClass()
      Returns the Class that this marshaller serializes and deserializes.
      T getMessagePrototype()
      An instance of the expected message type, typically used as a schema and helper for producing other message instances.
      T parse​(java.io.InputStream stream)
      Given an InputStream parse it into an instance of the declared type so that it can be passed to application code.
      private T parseFrom​(com.google.protobuf.CodedInputStream stream)  
      java.io.InputStream stream​(T value)
      Given a message, produce an InputStream for it so that it can be written to the wire.

      • getMessageClass

        public java.lang.Class<T> getMessageClass()
        Description copied from interface: MethodDescriptor.ReflectableMarshaller
        Returns the Class that this marshaller serializes and deserializes. If inheritance is allowed, this is the base class or interface for all supported classes.
        Specified by:
        getMessageClass in interface MethodDescriptor.ReflectableMarshaller<T extends com.google.protobuf.MessageLite>
        Returns:
        non-null base class for all objects produced and consumed by this marshaller

      • getMessagePrototype

        public T getMessagePrototype()
        Description copied from interface: MethodDescriptor.PrototypeMarshaller
        An instance of the expected message type, typically used as a schema and helper for producing other message instances. The null value may be a special value for the marshaller (like the equivalent of Void), so it is a valid return value. null does not mean "unsupported" or "unknown".

        It is generally expected this would return the same instance each invocation, but it is not a requirement.

        Specified by:
        getMessagePrototype in interface MethodDescriptor.PrototypeMarshaller<T extends com.google.protobuf.MessageLite>

      • stream

        public java.io.InputStream stream​(T value)
        Description copied from interface: MethodDescriptor.Marshaller
        Given a message, produce an InputStream for it so that it can be written to the wire. Where possible implementations should produce streams that are KnownLength to improve transport efficiency.
        Specified by:
        stream in interface MethodDescriptor.Marshaller<T extends com.google.protobuf.MessageLite>
        Parameters:
        value - to serialize.
        Returns:
        serialized value as stream of bytes.

      • parse

        public T parse​(java.io.InputStream stream)
        Description copied from interface: MethodDescriptor.Marshaller
        Given an InputStream parse it into an instance of the declared type so that it can be passed to application code.
        Specified by:
        parse in interface MethodDescriptor.Marshaller<T extends com.google.protobuf.MessageLite>
        Parameters:
        stream - of bytes for serialized value
        Returns:
        parsed value

      • parseFrom

        private T parseFrom​(com.google.protobuf.CodedInputStream stream)
             throws com.google.protobuf.InvalidProtocolBufferException
        Throws:
        com.google.protobuf.InvalidProtocolBufferException
