Constructor Detail

RegisteringDockFactory

public RegisteringDockFactory(DockFrontend frontend,
                              DockFactory<D,P,L> factory)
Creates a new factory

Parameters:
frontend - the frontend to which this factory will add new elements
factory - delegated used to read and create new elements
Method Detail

getID

public java.lang.String getID()
Description copied from interface: DockConverter
Gets the unique name of this converter. Please note that unique identifiers starting with "dock." should not be used by clients.

Specified by:
getID in interface DockConverter<D extends Dockable,P extends PerspectiveDockable,BackupFactoryData<L>>
Returns:
the id

estimateLocations

public void estimateLocations(BackupFactoryData<L> layout,
                              LocationEstimationMap children)
Description copied from interface: DockFactory
Tries to estimate the DockablePropertys of the children of the station which is represented by layout.
The children of this station accessible through children.getChild( ... ), this factory may also access the leafs in the tree of Dockables through children.getSubChild(...).
Note: this method must not set the successor of any DockableProperty, it is the callers responsibility to handle chains of stations.

Specified by:
estimateLocations in interface DockFactory<D extends Dockable,P extends PerspectiveDockable,BackupFactoryData<L>>
Parameters:
layout - this station
children - the children of the station, this method should call DockLayoutInfo.setLocation(DockableProperty) or LocationEstimationMap.setLocation(int, DockableProperty) and LocationEstimationMap.setLocation(int, int, DockableProperty) for as many children as possible

getLayout

public BackupFactoryData<L> getLayout(D element,
                                      java.util.Map<Dockable,java.lang.Integer> children)
Description copied from interface: DockConverter
Gets the layout of element. This method should create a new instance of the layout object, that new object should not be tied to element in any way. A layout can be living for a long period of time and might be used on another dockable object.

Specified by:
getLayout in interface DockConverter<D extends Dockable,P extends PerspectiveDockable,BackupFactoryData<L>>
Parameters:
element - the element for which a new layout should be created
children - a map containing unique identifiers for the children of the element. Children which are not in this map should not be stored in the layout.
The identifiers are in the range from 0 (incl.) to children.size() (excl.). The same identifiers will be used as indices by a LocationEstimationMap. See also DockFactory.estimateLocations(Object, LocationEstimationMap).
Returns:
the newly created, independent layout object.
