- Method Detail
  - freeze
```
void freeze()
```
    Freezes this component to prevent further changes. Override this to freeze internal data structures and dependent objects. Overrides must call super. Calling freeze on an already frozen class must have no effect.
  - isFrozen
```
boolean isFrozen()
```
    Inspect whether this object can be changed. If the object is immutable from construction, this should return true, even if freeze() never has been invoked.
    
    Returns:
    
    true if this instance is in an immutable state, false otherwise
