- All Implemented Interfaces:
    MessageLite, MessageLiteOrBuilder

      public abstract class AbstractMessageLite<MessageType extends AbstractMessageLite<MessageType,BuilderType>,BuilderType extends AbstractMessageLite.Builder<MessageType,BuilderType>>
      extends java.lang.Object
      implements MessageLite

  A partial implementation of the `MessageLite` interface which implements as many methods of that interface as possible in terms of other methods.

    - #### toByteString

          public ByteString toByteString()

      Description copied from interface: `MessageLite`
      Serializes the message to a `ByteString` and returns it. This is just a trivial wrapper around `MessageLite.writeTo(CodedOutputStream)`.
      Specified by:
        `toByteString` in interface `MessageLite`

    - #### toByteArray

          public byte[] toByteArray()

      Description copied from interface: `MessageLite`
      Serializes the message to a `byte` array and returns it. This is just a trivial wrapper around `MessageLite.writeTo(CodedOutputStream)`.
      Specified by:
        `toByteArray` in interface `MessageLite`

    - #### writeTo

          public void writeTo(java.io.OutputStream output)
                       throws java.io.IOException

      Description copied from interface: `MessageLite`
      Serializes the message and writes it to `output`. This is just a trivial wrapper around `MessageLite.writeTo(CodedOutputStream)`. This does not flush or close the stream.

      NOTE: Protocol Buffers are not self-delimiting. Therefore, if you write any more data to the stream after the message, you must somehow ensure that the parser on the receiving end does not interpret this as being part of the protocol message. This can be done e.g. by writing the size of the message before the data, then making sure to limit the input to that size on the receiving end (e.g. by wrapping the InputStream in one which limits the input). Alternatively, just use `MessageLite.writeDelimitedTo(OutputStream)`.

      Specified by:
        `writeTo` in interface `MessageLite`
      Throws:
        `java.io.IOException`

    - #### writeDelimitedTo

          public void writeDelimitedTo(java.io.OutputStream output)
                                throws java.io.IOException

      Description copied from interface: `MessageLite`
      Like `MessageLite.writeTo(OutputStream)`, but writes the size of the message as a varint before writing the data. This allows more data to be written to the stream after the message without the need to delimit the message data yourself. Use `MessageLite.Builder.mergeDelimitedFrom(InputStream)` (or the static method `YourMessageType.parseDelimitedFrom(InputStream)`) to parse messages written by this method.
      Specified by:
        `writeDelimitedTo` in interface `MessageLite`
      Throws:
        `java.io.IOException`

    - #### checkByteStringIsUtf8

          protected static void checkByteStringIsUtf8(ByteString byteString)
                                               throws java.lang.IllegalArgumentException

      Throws:
        `java.lang.IllegalArgumentException`

    - #### addAll

          protected static <T> void addAll(java.lang.Iterable<T> values,
                        java.util.Collection<? super T> list)
