State (liblayout JavaDoc)

All Superinterfaces:

java.io.Serializable

All Known Implementing Classes:

AbstractRenderer.RendererState, AbstractStyleResolver.AbstractStyleResolverState, ContentNormalizer.ContentNormalizerState, DefaultRenderableTextFactory.DefaultRenderableTextFactoryState, InstantiationState, PaginatingRenderer.DefaultFlowRendererState, StreamingRenderer.DefaultFlowRendererState
```
public interface State
extends java.io.Serializable
```
As it is said. Its a state. A state object is created by a StatefullComponent and is used to save and restore the state of that component. The state object must be immutable - and the restore methods must make sure that the state object's contents are not modified in any way.

  - restore
```
StatefullComponent restore(LayoutProcess layoutProcess)
                    throws StateException
```
    Creates a restored instance of the saved component. By using this factory-like approach, we gain independence from having to know the actual implementation. This makes things a lot easier.
    
    Parameters:
    
    layoutProcess - the layout process that controls it all
    
    Returns:
    
    the saved state
    
    Throws:
    
    StateException
