```
public final class UnknownFieldSet
extends java.lang.Object
implements MessageLite
```
UnknownFieldSet is used to keep track of fields which were seen when parsing a protocol message but whose field numbers or types are unrecognized. This most frequently occurs when new fields are added to a message type and then messages containing those fields are read by old software that was compiled before the new types were added.
Every Message contains an UnknownFieldSet (and every Message.Builder contains an UnknownFieldSet.Builder).
Most users will never need to use this class.

- Method Detail
  - newBuilder
```
public static UnknownFieldSet.Builder newBuilder()
```
    Create a new UnknownFieldSet.Builder.
  - newBuilder
```
public static UnknownFieldSet.Builder newBuilder(UnknownFieldSet copyFrom)
```
    Create a new UnknownFieldSet.Builder and initialize it to be a copy of copyFrom.
  - getDefaultInstance
```
public static UnknownFieldSet getDefaultInstance()
```
    Get an empty UnknownFieldSet.
  - getDefaultInstanceForType
```
public UnknownFieldSet 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.

```
    Get a map of fields in the set by number.

```
    Check if the given field number is present in the set.
  - getField
```
public UnknownFieldSet.Field getField(int number)

    Throws:
    
    java.io.IOException
  - toString
```
public java.lang.String toString()
```
    Converts the set to a string in protocol buffer text format. This is just a trivial wrapper around TextFormat.printToString(UnknownFieldSet).
    
    Overrides:
    
    toString in class java.lang.Object
  - toByteString
```
public ByteString toByteString()
```
    Serializes the message to a ByteString and returns it. This is just a trivial wrapper around writeTo(CodedOutputStream).
    
    Specified by:
    
    toByteString in interface MessageLite
  - toByteArray
```

```
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
