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<FlapDockStation,FlapDockPerspective,FlapDockStationLayout>

Returns:

the id

getLayout

public FlapDockStationLayout getLayout(FlapDockStation 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<FlapDockStation,FlapDockPerspective,FlapDockStationLayout>

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.

setLayout

public void setLayout(FlapDockStation station,
                      FlapDockStationLayout layout,
                      PlaceholderStrategy placeholders)

Description copied from interface: DockConverter

Reads the contents of layout and changes the layout of element accordingly. This method should not add or remove children to or from element.

Specified by:

setLayout in interface DockConverter<FlapDockStation,FlapDockPerspective,FlapDockStationLayout>

Parameters:

station - 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.

setLayout

public void setLayout(FlapDockStation station,
                      FlapDockStationLayout layout,
                      Map<Integer,Dockable> children,
                      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<FlapDockStation,FlapDockPerspective,FlapDockStationLayout>

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.

layoutPerspective

public FlapDockPerspective layoutPerspective(FlapDockStationLayout layout,
                                             Map<Integer,PerspectiveDockable> children)

Description copied from interface: DockFactory

Creates an element that can be used by a Perspective to create a layout without creating any DockElements. This method may return null only if the client is guaranteed not to use a Perspective.

Specified by:

layoutPerspective in interface DockFactory<FlapDockStation,FlapDockPerspective,FlapDockStationLayout>

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.

Returns:

the new element, can be null, the return value of PerspectiveElement.getFactoryID() should be equal to DockConverter.getID()

layoutPerspective

public void layoutPerspective(FlapDockPerspective perspective,
                              FlapDockStationLayout layout,
                              Map<Integer,PerspectiveDockable> children)

Description copied from interface: DockFactory

Updates the contents of perspective such that it reflects the contents of layout.

Specified by:

layoutPerspective in interface DockFactory<FlapDockStation,FlapDockPerspective,FlapDockStationLayout>

Parameters:

perspective - the perspective that is to be updated

layout - the layout to apply

children - the new children of perspective, is null if the children of this station are going to be ignored.

getPerspectiveLayout

public FlapDockStationLayout getPerspectiveLayout(FlapDockPerspective element,
                                                  Map<PerspectiveDockable,Integer> children)

Description copied from interface: DockConverter

Gets the layout information that is associated with element. The layout information can be any Object. The only restriction of the object is, that the associated DockFactory understands how to read that object.

Specified by:

getPerspectiveLayout in interface DockConverter<FlapDockStation,FlapDockPerspective,FlapDockStationLayout>

Parameters:

element - the element whose layout information is asked.

children - a map providing identifiers for the children of this element. The identifiers are in the range from 0 (incl.) to children.size() (excl.), the exact same identifiers would be given to DockConverter.getLayout(bibliothek.gui.dock.DockElement, Map). Is null if the children of this station should be ignored.

Returns:

the layout information, may be null if this converter does not support perspectives

estimateLocations

public void estimateLocations(FlapDockStationLayout 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(...).

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
