  bibliothek.gui.dock.common.intern.CommonSingleDockableFactory

All Implemented Interfaces:

DockFactory<CommonDockable,String>, DockConverter<CommonDockable,String>

public class CommonSingleDockableFactory
extends Object
implements DockFactory<CommonDockable,String>

This factory is used to create new SingleCDockables using various SingleCDockableBackupFactorys. This factory is accessed when a single dockable is missing in the cache of its owning CControl.

Constructor Detail

CommonSingleDockableFactory

public CommonSingleDockableFactory(CControl control)

Creates a new factory.

Parameters:

control - the owner of the factory, the factory will add SingleCDockable to this control

Method Detail

add

public void add(String id,
                SingleCDockableBackupFactory factory)

Registers a new factory that will load SingleCDockables with the unique id id.

Parameters:

id - the unique id of the dockables which factory will create

factory - the new factory

remove

public void remove(String id)

Removes a factory from this.

Parameters:

id - the name of the factory to remove

getFactory

public SingleCDockableBackupFactory getFactory(String id)

Searches the factory which was registered for id.

Parameters:

id - the name of a factory

Returns:

the factory or null

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<CommonDockable,String>

Returns:

the id

listFactories

public String[] listFactories()

Gets a list of keys for all factories known to this.

Returns:

the list of keys

getFactoryIds

public Set<String> getFactoryIds()

Gets the set of keys for all factories known to this.

Returns:

the set of keys

estimateLocations

public void estimateLocations(String 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<CommonDockable,String>

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 String getLayout(CommonDockable element,
                        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<CommonDockable,String>

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 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.

layout

public CommonDockable layout(String layout,
                             Map<Integer,Dockable> children)

Description copied from interface: DockFactory

Creates a new DockElement and changes the layout of the new element such that is matches layout.

Specified by:

layout in interface DockFactory<CommonDockable,String>

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.

Returns:

a new element or null if layout can't be used

layout

public CommonDockable layout(String layout)

Description copied from interface: DockFactory

Creates a new DockElement and changes the layout of the new element such that is matches layout. This method should not add any children to the element.

Specified by:

layout in interface DockFactory<CommonDockable,String>

Parameters:

layout - the new layout

Returns:

a new element or null if layout can't be used

read

public String read(DataInputStream in,
                   PlaceholderStrategy placeholders)
            throws IOException

Description copied from interface: DockConverter

Reads a layout from a stream.

Specified by:

read in interface DockConverter<CommonDockable,String>

Parameters:

in - the stream to read from

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

Returns:

the new layout, can be null if the layout should be discarded

Throws:

IOException - if an I/O-error occurs

read

public String read(XElement element,
                   PlaceholderStrategy placeholders)

Description copied from interface: DockConverter

Reads a layout from an xml-element.

Specified by:

read in interface DockConverter<CommonDockable,String>

Parameters:

element - the element to read, should not be changed by this method.

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

Returns:

the new layout, can be null if the layout should be discarded

setLayout

public void setLayout(CommonDockable element,
                      String layout,
                      Map<Integer,Dockable> children)

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<CommonDockable,String>

Parameters:

element - 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.

setLayout

public void setLayout(CommonDockable element,
                      String layout)

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<CommonDockable,String>

layout - the new set of properties

write

public void write(String layout,

                  XElement element)

Description copied from interface: DockConverter

Writes the contents of layout into element.

Specified by:

write in interface DockConverter<CommonDockable,String>

Parameters:

layout - the layout to store
