  - getFixedSize
```
public int getFixedSize()
```
    Specified by:
    
    getFixedSize in interface Codec<T>
    
    Returns:
    
    -1 if the object do not always marshall to a fixed size, otherwise return that fixed size.
  - isDeepCopySupported
```
public boolean isDeepCopySupported()
```
    Specified by:
    
    isDeepCopySupported in interface Codec<T>
    
    Returns:
    
    true if the Codec.deepCopy(Object) operations is supported.
  - deepCopy
```
public T deepCopy(T source)
```
    Specified by:
    
    deepCopy in interface Codec<T>
    
    Returns:
    
    a deep copy of the source object. If the source is immutable the same source should be returned.
  - isEstimatedSizeSupported
```
public boolean isEstimatedSizeSupported()
```
    Specified by:
    
    isEstimatedSizeSupported in interface Codec<T>
    
    Returns:
    
    true if the Codec.estimatedSize(Object) operation is supported.
  - estimatedSize
```
public int estimatedSize(T object)
```
    Specified by:
    
    estimatedSize in interface Codec<T>
    
    Returns:
    
    the estimated marshaled size of the object.
