public interface Freezable
extends java.lang.Cloneable
```
Auto-serializer interface using a delegator pattern (the faster option is to byte-code gen directly in all Iced classes, but this requires all Iced classes go through a ClassLoader).
Freeazable is a marker interface, and Iced is the companion marker class. Marked classes have 2-byte integer type associated with them, and an auto-genned delegate class created to actually do serialization. Serialization is extremely dense (includes various compressions), and typically memory-bandwidth bound to generate.
H2O uses Iced classes as the primary means of moving Java Objects around the cluster.

- Method Detail
  - write
```
AutoBuffer write(AutoBuffer ab)
```
    Standard "write thyself into the AutoBuffer" call, using the fast Iced protocol. Real work is in the delegate Icer classes.
    
    Parameters:
    ab - AutoBuffer to write this object to.
    
    Returns:
    Returns the original AutoBuffer for flow-coding.
  - read
```
<T extends Freezable> T read(AutoBuffer ab)
```
    Standard "read thyself from the AutoBuffer" call, using the fast Iced protocol. Real work is in the delegate Icer classes.
    
    Type Parameters:
    T - Type of returned object
    Parameters:
    ab - AutoBuffer to read this object from.
    
    Returns:
    Returns a new instance of object reconstructed from AutoBuffer.
  - writeJSON
```
AutoBuffer writeJSON(AutoBuffer ab)
```
    Standard "write thyself into the AutoBuffer" call, using JSON. Real work is in the delegate Icer classes.
    
    Parameters:
    ab - AutoBuffer to write this object to.
    
    Returns:
    Returns the original AutoBuffer for flow-coding.
  - readJSON
```
<T extends Freezable> T readJSON(AutoBuffer ab)
```
    Standard "read thyself from the AutoBuffer" call, using JSON. Real work is in the delegate Icer classes.
    
    Type Parameters:
    T - Type of returned object
    Parameters:
    ab - AutoBuffer to read this object from.
    
    Returns:
    Returns an instance of object reconstructed from JSON data.
  - writeHTML
```
DocGen.HTML writeHTML(DocGen.HTML sb)
```
    Standard "write thyself into the AutoBuffer" call, using HTML. Real work is in the delegate Icer classes.
    
    Parameters:
    sb - target to serialize this object in HTML form
    
    Returns:
    Returns the original AutoBuffer for flow-coding.
  - frozenType
```
int frozenType()
```
    Returns a small dense integer, which is cluster-wide unique per-class. Useful as an array index.
    
    Returns:
    Small integer, unique per-type
  - clone
```
<T extends Freezable> T clone()
```
    Clone, without the annoying exception.
    
    Type Parameters:
    T - Type of returned object
    
    Returns:
    Returns this object cloned.
