Class AbstractCStation<S extends CommonDockStation<?,?>>

java.lang.Object
  bibliothek.gui.dock.common.intern.AbstractCStation<S>

Type Parameters:

S - the kind of station this CStation is built upon

All Implemented Interfaces:

CStation<S>

Direct Known Subclasses:

CExternalizeArea

public abstract class AbstractCStation<S extends CommonDockStation<?,?>>
extends Object
implements CStation<S>

A simple implementation of CStation. This class adds a install(CControlAccess) and uninstall(CControlAccess) method, subclasses do not have to track or store the CControlAccess that is given in setControlAccess(CControlAccess).

Constructor Summary

protected	AbstractCStation() Creates a new station but does not yet initialize its fields.
	AbstractCStation(S station, String id, CLocation location) Creates a new station.

Method Summary

CDockable	asDockable() If this station is a CDockable as well, then this method returns the representation of this station as CDockable.
protected CControlAccess	getControl() Gets the currently used CControlAccess.
CLocation	getDropLocation() Creates a CLocation that can be used to drop a new CDockable on this station or one of its children stations.
S	getStation() Gets the internal representation of this CStation.
CLocation	getStationLocation() Gets a location which represents directly CStation.getStation().
String	getUniqueId() Gets a unique and constant identifier for this station
protected void	init(S station, String id, CLocation location) Initializes the fields of this station.
protected abstract void	install(CControlAccess access) Called when this station is added to a CControl.
boolean	isWorkingArea() Tells whether this station is a special working area or not.
void	setControlAccess(CControlAccess access) Called by CControl when this CStation is added or removed.

Constructor Detail

AbstractCStation

public AbstractCStation(S station,
                        String id,
                        CLocation location)

Creates a new station.

Parameters:

station - the internal representation of this station

id - the unique id of this station

location - a location that points directly to this station

AbstractCStation

protected AbstractCStation()

Creates a new station but does not yet initialize its fields. Subclasses should call init(CommonDockStation, String, CLocation).

Method Detail

init

protected void init(S station,
                    String id,
                    CLocation location)

Initializes the fields of this station.

Parameters:

station - the internal representation of this station

id - the unique id of this station

location - a location that points directly to this station

getStationLocation

public CLocation getStationLocation()

Description copied from interface: CStation

Gets a location which represents directly CStation.getStation().

Specified by:

getStationLocation in interface CStation<S extends CommonDockStation<?,?>>

Returns:

the location that will always represent the station

getDropLocation

public CLocation getDropLocation()

Description copied from interface: CStation

Creates a CLocation that can be used to drop a new CDockable on this station or one of its children stations. This method returns the "optimal spot", where the definition of "optimal spot" is up to the station itself. The default implementations however call CLocationModeManager.getDropLocation(CStation).

Specified by:

getDropLocation in interface CStation<S extends CommonDockStation<?,?>>

Returns:

the optimal spot for dropping a new CDockable or null if this station is not able to calculate the optimal spot (e.g. because the station is not visible)

getUniqueId

public String getUniqueId()

Description copied from interface: CStation

Gets a unique and constant identifier for this station

Specified by:

getUniqueId in interface CStation<S extends CommonDockStation<?,?>>

Returns:

the unique identifier

getStation

public S getStation()

Description copied from interface: CStation

Gets the internal representation of this CStation.

Specified by:

getStation in interface CStation<S extends CommonDockStation<?,?>>

Returns:

the internal representation

setControlAccess

public void setControlAccess(CControlAccess access)

Description copied from interface: CStation

Called by CControl when this CStation is added or removed. There are two actions which most stations might want to do:

• Call one of the add methods for ModeAreas accessible through the CLocationModeManager. That will ensure that the station can be used as minimize/normalize/... area.
• Add a ResizeRequestListener to CControl in order to be informed when resize requests are to be handled.

Specified by:

setControlAccess in interface CStation<S extends CommonDockStation<?,?>>

Parameters:

access - access to the internals of the CControl that uses this station or null to remove all ties from a control

getControl

protected CControlAccess getControl()

Gets the currently used CControlAccess.

Returns:

access to the current CControl, can be null

isWorkingArea

public boolean isWorkingArea()

Description copied from interface: CStation

Tells whether this station is a special working area or not. It is not possible drag a child from a working area if it is registered there, or to drop a child onto a working area if it is not registered there.
Working areas must either be registered as root-station (see CControl.addStation(CStation, boolean)) or must be a SingleCDockable.

Specified by:

isWorkingArea in interface CStation<S extends CommonDockStation<?,?>>

Returns:

true if this is a working area, false otherwise

asDockable

public CDockable asDockable()

Description copied from interface: CStation

If this station is a CDockable as well, then this method returns the representation of this station as CDockable.

Specified by:

asDockable in interface CStation<S extends CommonDockStation<?,?>>

Returns:

this as dockable or null

install

protected abstract void install(CControlAccess access)

Called when this station is added to a CControl.

Parameters:

access - access to the internals of the new owner

uninstall

protected abstract void uninstall(CControlAccess access)

Called when this station is removed from a CControl.

Parameters:

access - access to the internals of the old owner
