  - get
```
public static ImmutableNilValue get()
```
  - getValueType
```
public ValueType getValueType()
```
    Description copied from interface: Value
    
    Returns type of this value. Note that you can't use instanceof to check type of a value because type of a mutable value is variable.
    
    Specified by:
    
    getValueType in interface Value
  - immutableValue
```
public ImmutableNilValue immutableValue()
```
    Description copied from interface: Value
    
    Returns immutable copy of this value. This method simply returns this without copying the value if this value is already immutable.
    
    Specified by:
    
    immutableValue in interface Value
  - asNilValue
```
public ImmutableNilValue asNilValue()
```
    Description copied from interface: Value
    
    Returns the value as NilValue. Otherwise throws MessageTypeCastException. Note that you can't use instanceof or cast ((NilValue) thisValue) to check type of a value because type of a mutable value is variable.

  - writeTo
```
public void writeTo(MessagePacker pk)
             throws java.io.IOException
```
    Description copied from interface: Value
    
    Serializes the value using the specified MessagePacker
    
    Specified by:

  - equals
```
public boolean equals(java.lang.Object o)
```
    Description copied from interface: Value
    
    Compares this value to the specified object. This method returns true if type and value are equivalent. If this value is MapValue or ArrayValue, this method check equivalence of elements recursively.
    
    Specified by:
    
    equals in interface Value
    
    Overrides:
    
    equals in class java.lang.Object
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class java.lang.Object
  - toString
```
public java.lang.String toString()
```
    Overrides:
    
    toString in class java.lang.Object
  - toJson
```
public java.lang.String toJson()
```
    Description copied from interface: Value
    Returns json representation of this Value.
    Following behavior is not configurable at this release and they might be changed at future releases:
    - if a key of MapValue is not string, the key is converted to a string using toString method.
    - NaN and Infinity of DoubleValue are converted to null.
    - ExtensionValue is converted to a 2-element array where first element is a number and second element is the data encoded in hex.
    - BinaryValue is converted to a string using UTF-8 encoding. Invalid byte sequence is replaced with U+FFFD replacement character.
    - Invalid UTF-8 byte sequences in StringValue is replaced with U+FFFD replacement character
