Method Detail

getID

public 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<StackDockStation,StackDockPerspective,StackDockStationLayout>

Returns:

the id

getLayout

public StackDockStationLayout getLayout(StackDockStation station,
                                        Map<Dockable,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<StackDockStation,StackDockPerspective,StackDockStationLayout>

Parameters:

station - 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.

estimateLocations

public void estimateLocations(StackDockStationLayout 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 are 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<StackDockStation,StackDockPerspective,StackDockStationLayout>

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

setLayout

public void setLayout(StackDockStation station,
                      StackDockStationLayout layout,

                      PlaceholderStrategy placeholders)

Description copied from interface: DockConverter

Reads the contents of layout and changes the layout of element accordingly. This method should remove all children from element and add new children.

Specified by:

setLayout in interface DockConverter<StackDockStation,StackDockPerspective,StackDockStationLayout>

Parameters:

station - the element whose content and children will be rearranged.

layout - the new layout of element

children - some children, note that the map may not contain all elements which were present when the layout was created.

placeholders - a strategy to detect invalid placeholders, can be null. Factories loading only Dockables but no DockStations can safely ignore this argument.

Specified by:

setLayout in interface DockConverter<StackDockStation,StackDockPerspective,StackDockStationLayout>

Parameters:

element - the element whose properties will be changed

layout - the new set of properties

placeholders - a strategy to detect invalid placeholders, can be null. Factories loading only Dockables but no DockStations can safely ignore this argument.

Specified by:

layoutPerspective in interface DockFactory<StackDockStation,StackDockPerspective,StackDockStationLayout>

Parameters:

layout - the new layout

children - some children, note that the map may not contain all elements which were present when the layout was created. Is null if the children of this station are going to be ignored.
