Class ALcyCameraLinker
- All Implemented Interfaces:
ILcdPropertyChangeSource
- Direct Known Subclasses:
ALcyLspCameraLinker2D
,ALcyLspCameraLinker3D
Implementations of this class should do all that is necessary to set the tracking camera on the view, and/or enable a specialized controller, and be able to revert back to the state before the tracking was enabled. Implementations will typically need to know a list of objects, their models, and a map component.
For workspace support, a ALcyWorkspaceObjectCodec for each ALcyCameraLinker implementation should be created.
An ALcyCameraLinker is created by a ALcyCameraLinkerFactory

setLinked
public abstract void setLinked(boolean aLinked) Link or unlink the camera.- Parameters:
aLinked
- Whether or not to link the camera.
-
isLinked
public abstract boolean isLinked()Check if the camera is linked.- Returns:

addPropertyChangeListener
Description copied from interface:ILcdPropertyChangeSource
Registers the given
PropertyChangeListener
to be notified when this object's properties change.In case you need to register a listener which keeps a reference to an object with a shorter life-time than this change source, you can use a
ALcdWeakPropertyChangeListener
instance as property change listener.- Specified by:
addPropertyChangeListener
in interfaceILcdPropertyChangeSource
- Parameters:
aListener
- The listener to be notified- See Also:
-
addPropertyChangeListener
Adds the given listener to the list of listeners, so that it will receive notifications about changes inaProperty
.- Parameters:
aProperty
- The property to watch for changes.aListener
- The listener to add.
-
removePropertyChangeListener
Description copied from interface:ILcdPropertyChangeSource
De-registers the given
PropertyChangeListener
from receiving property change events for this object.If the listener was added more than once, it will be notified one less time after being removed. If the listener is
null
, or was never added, no exception is thrown and no action is taken.- Specified by:
removePropertyChangeListener
in interfaceILcdPropertyChangeSource
- Parameters:
aListener
- the listener that should no longer be notified of changes of this object's properties- See Also:
-
removePropertyChangeListener
Removes the given listener for the given property, so that it no longer receives those change events.- Parameters:
aProperty
- The property to stop listening to.aListener
- The listener to remove.
-
firePropertyChange
Fires the given event to the associated listeners.- Parameters:
aProperty
- The property that was changed.aOldValue
- The old value.aNewValue
- The new value.
