protected AbstractLayoutController()
```
- Method Detail
  - getParent
```
public LayoutController getParent()
```
    Retrieves the parent of this layout controller. This allows childs to query their context.
    
    Specified by:
    
    getParent in interface LayoutController
    
    Returns:
    
    the layout controller's parent to null if there is no parent.
  - initialize
```
public void initialize(java.lang.Object node,
                       FlowController flowController,
                       LayoutController parent)
                throws DataSourceException,
                       ReportDataFactoryException,
                       ReportProcessingException
```
    Initializes the layout controller. This method is called exactly once. It is the creators responsibility to call this method.
    Calling initialize after the first advance must result in a IllegalStateException.
    
    Specified by:
    
    initialize in interface LayoutController
    
    Parameters:
    
    node - the currently processed object or layout node.
    
    flowController - the current flow controller.
    
    parent - the parent layout controller that was responsible for instantiating this controller.
    
    Throws:
    
    DataSourceException - if there was a problem reading data from the datasource.
    
    ReportProcessingException - if there was a general problem during the report processing.
    
    ReportDataFactoryException - if a query failed.
  - clone
```
public java.lang.Object clone()
```
    Description copied from interface: LayoutController
    
    Creates a copy of this layout controller.
    
    Specified by:
    
    clone in interface LayoutController
    
    Overrides:
    
    clone in class java.lang.Object
    
    Returns:
    
    a copy.
  - getFlowController
```
public FlowController getFlowController()
```
    Specified by:
    
    getFlowController in interface LayoutController
  - getNode
```
public java.lang.Object getNode()
```
    Specified by:
    
    getNode in interface LayoutController
  - isInitialized
```
public boolean isInitialized()
```
  - createPrecomputeInstance
```
public LayoutController createPrecomputeInstance(FlowController fc)
```
    Derives a copy of this controller that is suitable to perform a precomputation.
    
    Specified by:
    
    createPrecomputeInstance in interface LayoutController
    
    Parameters:
    
    fc -
    
    Returns:
