```

```
    Description copied from interface: MessageLite.Builder
    
    Resets all fields to their default values.
  - findInitializationErrors
```
public List<String> findInitializationErrors()
```
    Description copied from interface: MessageOrBuilder
    
    Returns a list of field paths (e.g. "foo.bar.baz") of required fields which are not set in this message. You should call MessageLiteOrBuilder.isInitialized() first to check if there are any missing fields, as that method is likely to be much faster than this one even when the message is fully-initialized.
  - getInitializationErrorString
```
public String getInitializationErrorString()
```
    Description copied from interface: MessageOrBuilder
    
    Returns a comma-delimited list of required fields which are not set in this message object. You should call MessageLiteOrBuilder.isInitialized() first to check if there are any missing fields, as that method is likely to be much faster than this one even when the message is fully-initialized.
  - mergeFrom
```
public BuilderType mergeFrom(Message other)
```
    Description copied from interface: Message.Builder
    
    Merge other into the message being built. other must have the exact same type as this (i.e. getDescriptorForType() == other.getDescriptorForType()). Merging occurs as follows. For each field:
    * For singular primitive fields, if the field is set in other, then other's value overwrites the value in this message.
    * For singular message fields, if the field is set in other, it is merged into the corresponding sub-message of this message using the same merging rules.
    * For repeated fields, the elements in other are concatenated with the elements in this message. This is equivalent to the Message::MergeFrom method in C++.
  - mergeFrom
```
public BuilderType mergeFrom(CodedInputStream input)
                      throws IOException
```
    Description copied from interface: MessageLite.Builder
    Parses a message of this type from the input and merges it with this message.
    Warning: This does not verify that all required fields are present in the input message. If you call MessageLite.Builder.build() without setting all required fields, it will throw an UninitializedMessageException, which is a RuntimeException and thus might not be caught. There are a few good ways to deal with this:
    - Call MessageLiteOrBuilder.isInitialized() to verify that all required fields are set before building.
    - Use buildPartial() to build, which ignores missing required fields.
    Note: The caller should call CodedInputStream.checkLastTagWas(int) after calling this to verify that the last tag seen was the appropriate end-group tag, or zero for EOF.

    Description copied from interface: MessageLite.Builder
    
    Like MessageLite.Builder.mergeFrom(CodedInputStream), but also parses extensions. The extensions that you want to be able to parse must be registered in extensionRegistry. Extensions not in the registry will be treated as unknown fields.

  - getFieldBuilder
```
public Message.Builder getFieldBuilder(Descriptors.FieldDescriptor field)
```
    Description copied from interface: Message.Builder
    
    Get a nested builder instance for the given field.
    Normally, we hold a reference to the immutable message object for the message type field. Some implementations(the generated message builders), however, can also hold a reference to the builder object (a nested builder) for the field.
    
    If the field is already backed up by a nested builder, the nested builder will be returned. Otherwise, a new field builder will be created and returned. The original message field (if exist) will be merged into the field builder, which will then be nested into its parent builder.
    
    NOTE: implementations that do not support nested builders will throw UnsupportedException.

public BuilderType mergeFrom(InputStream input)

```
    Description copied from interface: MessageLite.Builder
    
    Parse a message of this type from input and merge it with the message being built. This is just a small wrapper around MessageLite.Builder.mergeFrom(CodedInputStream). Note that this method always reads the entire input (unless it throws an exception). If you want it to stop earlier, you will need to wrap your input in some wrapper stream that limits reading. Or, use MessageLite.writeDelimitedTo(OutputStream) to write your message and MessageLite.Builder.mergeDelimitedFrom(InputStream) to read it.
    Despite usually reading the entire input, this does not close the stream.

    Like MessageLite.Builder.mergeFrom(InputStream), but does not read until EOF. Instead, the size of the message (encoded as a varint) is read first, then the message data. Use MessageLite.writeDelimitedTo(OutputStream) to write messages in this format.
