    Construct a Message.Builder for the given type.
  - newBuilder
```
public static DynamicMessage.Builder newBuilder(Message prototype)
```
    Construct a Message.Builder for a message of the same type as prototype, and initialize it with prototype's contents.
  - getDescriptorForType
```
public Descriptors.Descriptor getDescriptorForType()
```
    Description copied from interface: MessageOrBuilder
    
    Get the message's type's descriptor. This differs from the getDescriptor() method of generated message classes in that this method is an abstract method of the Message interface whereas getDescriptor() is a static method of a specific class. They return the same thing.
  - getDefaultInstanceForType
```
public DynamicMessage getDefaultInstanceForType()
```
    Description copied from interface: MessageLiteOrBuilder
    
    Get an instance of the type with no fields set. Because no fields are set, all getters for singular fields will return default values and repeated fields will appear empty. This may or may not be a singleton. This differs from the getDefaultInstance() method of generated message classes in that this method is an abstract method of the MessageLite interface whereas getDefaultInstance() is a static method of a specific class. They return the same thing.
  - getAllFields
```
public Map<Descriptors.FieldDescriptor,Object> getAllFields()
```
    Description copied from interface: MessageOrBuilder
    
    Returns a collection of all the fields in this message which are set and their corresponding values. A singular ("required" or "optional") field is set iff hasField() returns true for that field. A "repeated" field is set iff getRepeatedFieldCount() is greater than zero. The values are exactly what would be returned by calling MessageOrBuilder.getField(Descriptors.FieldDescriptor) for each field. The map is guaranteed to be a sorted map, so iterating over it will return fields in order by field number.
    If this is for a builder, the returned map may or may not reflect future changes to the builder. Either way, the returned map is itself unmodifiable.
  - hasOneof
```
public boolean hasOneof(Descriptors.OneofDescriptor oneof)
```
    Description copied from class: AbstractMessage
    
    TODO(jieluo): Clear it when all subclasses have implemented this method.
  - getOneofFieldDescriptor
```
public Descriptors.FieldDescriptor getOneofFieldDescriptor(Descriptors.OneofDescriptor oneof)
```
    Description copied from class: AbstractMessage
    
    TODO(jieluo): Clear it when all subclasses have implemented this method.
  - hasField
```
public boolean hasField(Descriptors.FieldDescriptor field)
```
    Description copied from interface: MessageOrBuilder
    
    Returns true if the given field is set. This is exactly equivalent to calling the generated "has" accessor method corresponding to the field.
  - getField
```
public Object getField(Descriptors.FieldDescriptor field)
```
    Description copied from interface: MessageOrBuilder
    
    Obtains the value of the given field, or the default value if it is not set. For primitive fields, the boxed primitive value is returned. For enum fields, the EnumValueDescriptor for the value is returned. For embedded message fields, the sub-message is returned. For repeated fields, a java.util.List is returned.
  - getRepeatedFieldCount
```
public int getRepeatedFieldCount(Descriptors.FieldDescriptor field)
```
    Description copied from interface: MessageOrBuilder
    
    Gets the number of elements of a repeated field. This is exactly equivalent to calling the generated "Count" accessor method corresponding to the field.
  - getRepeatedField
```
public Object getRepeatedField(Descriptors.FieldDescriptor field,
                               int index)
```
    Description copied from interface: MessageOrBuilder
    
    Gets an element of a repeated field. For primitive fields, the boxed primitive value is returned. For enum fields, the EnumValueDescriptor for the value is returned. For embedded message fields, the sub-message is returned.
  - getUnknownFields
```
public UnknownFieldSet getUnknownFields()
```
    Description copied from interface: MessageOrBuilder
    
    Get the UnknownFieldSet for this message.
  - isInitialized
```
public boolean isInitialized()
```
    Description copied from interface: MessageLiteOrBuilder
    
    Returns true if all required fields in the message and all embedded messages are set, false otherwise.
    See also: MessageOrBuilder.getInitializationErrorString()
  - writeTo
```
public void writeTo(CodedOutputStream output)
             throws IOException
```
    Description copied from interface: MessageLite
    
    Serializes the message and writes it to output. This does not flush or close the stream.
    
    Specified by:
    
    writeTo in interface MessageLite
    
    Overrides:
    
    writeTo in class AbstractMessage
    
    Throws:
    
    IOException
  - getSerializedSize
```
public int getSerializedSize()
```
    Description copied from interface: MessageLite
    
    Get the number of bytes required to encode this message. The result is only computed on the first call and memoized after that.
  - newBuilderForType
```
public DynamicMessage.Builder newBuilderForType()
```
    Description copied from interface: MessageLite
    
    Constructs a new builder for a message of the same type as this message.
  - toBuilder
```
public DynamicMessage.Builder toBuilder()
```
    Description copied from interface: MessageLite
    
    Constructs a builder initialized with the current message. Use this to derive a new message from the current one.
  - getParserForType
```
public Parser<DynamicMessage> getParserForType()
```
    Description copied from interface: MessageLite
    
    Gets the parser for a message of the same type as this message.
